Welcome to the Jorne keyboard hardware wiki!

Jorne is an extended Corne with extra keys for brackets and international layouts (100% original Corne if keys snapped off).

Also check out nRFMicro wiki. Also see MechDB, Awesome Split Keyboards, Dao, Nijuni (RT-22), Chokofi, Khonsu and Mriya.

TL;DR

Download PCB gerbers here: jorne-classic-2.1-gerbers.zip Upload to JLCPCB (default settings, 1.6mm 2-layer PCB, 5 or 10 pcs), pay something. Order parts on Aliexpress. Read this wiki for two weeks. Get the mail. You can snap off pinky keys and use standard Corne case, if needed. How to order PCBs if you are in the sanctioned countries: https://t.me/devAlphaSierra/359

Disclaimer

Like I said, you can go to the moon without a computer, so, you know, the thing we are talking about is 40% keyboard, which means only 40 keys. It's very hard to type Chinese, Japanse, Russian with 40% keyboard. It's like doubling your work. Yeah, you can. But if you need to type that two hours a day you gonna see a doctor within a month.

Versions

There are 3 base versions of Jorne (all versions are 44 keys, RGB, MX spacing):

The main idea behind Jorne is that it turns into Corne (same schematic/dimensions) if you snap off the extra keys.

2.1 vs 3.0

3.0 was added as a courtesy to Foostan just to have an option. I strongly recommend 2.1.

  • 3.0 is more expensive, 3.0 PCB is not reversible so you need two different designs, it's about 2x the price.
  • 3.0 needs two LED types which is also more expensive. SK6812MINI-E are easier to solder, but not by much.
  • 3.0 south-facing switches are questionnable. Most RGB caps have legends on top so they don't work with south facing switches. Using opaque caps with RGB is dumb (they block 90% of the light). Front-printed RGB caps are pretty rare.

Bill of Materials

Aliexpress Saver shipping is combined with the Standard shipping now, so use Saver where possible to get everyhing at once.

Picture Component name, description and buying instructions Need Store
Pro Micro Pro Micros (18mm wide, need 2). Black MicroUSB (recommended) and blue USB-C are compatible with the Spring pin headers, purple USB-C and blue MicroUSB are not (holes >0.85mm). Large blue USB-C don't support C-C cables. 2 Aliexpress
OLED White OLED screens, 128x32, cost about $1.50 a pcs. 2 Aliexpress (Great-Wall)
Headers 3.5mm pin headers to hotswap displays and Pro Micros. Optional. Also see Sockets. 2 Aliexpress ($2.99/5) Aliexpress ($4.99/10)
1N5819 SOD-123 1N4148 diodes (LL4148 substitute in SMD package). I use small 1N5819 in SOD-323 both in Jorne and nRFMicro, they work fine. You can use large 1N4148 in SOD-123, they're much easier to solder. 44 Aliexpress (Yanxy)
TRRS TRRS sockets, PJ-320A. About $1.32/20. See pinout here: TRRS. 2 Aliexpress (black) Aliexpress (white)
Buttons DIP 3x6x4.3mm tactile button. Also side buttons if you prefer those. 2 Aliexpress (black/white)
TRRS Cable TRRS Cable, Angled, 30cm, $0.69 a pcs (15 cm may be a little bit too short). Note that any TRS 3-pin audio cable is ok, so this is optional. 1 Aliexpress (30cm) Aliexpress (15cm)
Bumpons Black 3m bumpons for legs (height 3mm), also clear ones, they sell for about $1.30/100 pcs. 10 Aliexpress (black) Aliexpress   (clear)
M2 screws Cap head hexagon screws. Use M2 6mm (28 pcs) for the keyboard. Optional screws for tilting/tenting are M5 (2x30mm + 2x16mm). 28 Aliexpress ($1.70/50) Chrome Countersink Laptop
M2 standoffs M2 Standoffs, 8mm for 1.5mm plate (or 6mm for 3mm plate) - 10 pcs, 10mm for OLED - 4 pcs. Nylon hexagonal standoffs are too thick for PCBs, don't buy nylon. 14 Aliexpress ($1.24/20) Aliexpress (inserts)
SK6812MINI Jorne V2.1 only. Small 3.5x3.5 mm 3535 LEDs SK6812MINI. Pinout is NOT compatible with reverse mount SK6812MINI-E (rotated by 90). 56 Aliexpress ($9.54/100)
SK6812MINI-E Jorne V3 only. Small 3.5x3.5 mm SK6812MINI-E 3535LEDs (reverse mount). Per-key only (need 44). 44 Aliexpress ($7.68/50)
WS2812B Jorne V3 only. Large 5x5mm WS2812B 5050 LEDs (planar SK6812MINI-E like pinout). Ambient only (need 12). 12 Aliexpress ($3.45/50)
Kailh Kailh hotswap sockets for the hotswap version. Optional, Cherry (hotswap) versions only. Jorne doesn't support Choc sockets, only MX ones. Cost $0.10 a pcs. 44 Aliexpress (black) Aliexpress (white)
Cheapest silent 3-pin switches (I only use silent ones) by Outemu (180 CNY ~ $27 for 200 pcs ~ 13 cents a switch on Taobao, $45/200 ~ 22 cents a switch on Aliexpress). Silent grey is tactile, silent white is linear (recommended). 44 Reddit Taobao Aliexpress Aliexpress (cheaper)
Cheapest non-silent 3-pin MX switches ever, marked YUSYA. $6.15/110 ~ 5 cents a switch. Price may vary. There are other cheap noname switches, like CONTENT. 44 Aliexpress (YUSYA) Aliexpress (CONTENT)
Cheap Kailh LP (Choc, CPG1350) switches. I like red ones (yellows are too heavy, browns are too scratchy considering reduced travel). They costed $0.35 back in 2018, now the price is $0.55-0.75. They need 1.2 mm top plate to snap onto (or no plate). 44 Aliexpress KPRepublic MKUltra Aliexpress (superlight)
ABS Cheapest backlit MX keycaps, white and black, you can buy them in bulks for about $5 a 104-key set (order by price and free shipping) 1 Aliexpress (direct) Aliexpress (search)
Optional DSA MX keycaps (Cool Jazz), many colors including translucent black, ~$0.20 a cap 44 Aliexpress (color) Aliexpress (black)
Optional expensive MDA VoID, MX keycaps with 1u Raise/Lower, made especially for 40% keyboards, $78 + shipping (use https://zenmarket.jp for shipping) 1 Booth.pm
Cheap Kailh LP Keycaps from Kailh, they sell in bulks, $15.99 a 60 pcs/lot ~ $0.26 a cap. Transparent choc keycaps are more comfortable but they're NOT Choc spacing (larger than 18x17 mm), so they won't fit Ferris etc. Buy black or white keycaps for Choc spacing (white are rather yellow-ish so maybe only buy black ones). 44 Aliexpress (various) Aliexpress (backlit)
Optional expensive MBK choc (LP) keycaps (Corne-ish Zen uses them). Choc spacing (17.5x16.5 mm). 44 SplitKB Littlekeyboards Boardsource
MBK Clone choc keycaps (Chocfox), Cost $25/50 pcs. Official dimensions are 16.5x16.5mm so they DO fit choc spacing boards (18x17mm PCBs), see chocfox site. They are square, so there are 1mm horizontal gaps on choc spacing, a bit worse than MBK. 1 Aliexpress Chosfox

Note you cannot hotswap Chocs (Kailh LP) switches on Jorne, there's no PCB for Choc sockets, so soldering only.

If you want Space Invaders switches, someone discovered 2408 new old stock NMB keyboards in Germany, bought out the lot for 2408 eur. All keyboards except ~2% use Hi-Tek 725 Space Invaders (2 and 3 generation). Shipping space invaders keeb to europe starts from 30 EUR + 20 EUR for the keeb ~ 50 EUR total (GH), join discord here: https://discord.gg/9FTQhfV7uq

Equipment

See https://github.com/joric/nrfmicro/wiki/Soldering

Side View

PLEASE REFER TO THIS PICTURE BEFORE ASKING QUESTIONS, GRID IS 1x1 mm.

jorne_standoffs

  • WARNING! Don't use 1.5mm acrylic for the top plate, it's too fragile. Use FR4, steel or aluminum.
  • Don't use 6mm standoffs for 1.5mm plate because they are too short! Use 8 mm standoffs.

Build guide

See Corne (Helidox) build guides (the PCB is the same, except pinky key that can be snapped off).

Diodes

Diodes are polarized components, they have a specific orientation that has to be connected properly in order to work.

Untitled-1

The key (a spot or a line) on the diode should match the key on the footprint, e.g. for LL4148 diodes:

diodePosition

Pro Micro

TL;DR: footprints are ASYMMETRICAL. One of the pro micros is shifted one row of pins closer towards the edge.

assymetry

Solder OLED jumpers from the face side only. Do NOT solder OLED jumpers from the back side, this is the same as shorting VCC and GND together.

LEFT half is different from RIGHT half. LEFT half is flush with the edge, RIGHT half is shifted 1 row of pins to the right. Controllers must be installed face down.

Untitled-1

Remember, desoldering is much harder than soldering, so think twice before you solder something with many legs.

TRRS

MJ-4PP-9 (TRRS socket, I use PJ-320A as a substitute) pinout is counterintuitive, so here is a picture:

trrs

On some Ergogen keyboards (e.g. A.Dux) TRS cables short VCC and GND together, there's no fix because the narrow (symmetric) footprint used there already shorts Sleeve and Tip so we only get 2 usable pins on TRS. See issue #15.

QMK uses single-wire duplex serial since Helix so you can use TRS (3-wire stereo cables) and don't need to solder i2c resistors and lose OLED. TRS connectors short together DATA (RX) pad and I2C (floating) pad, but it doesn't affect data transfer.

Note that TRS/TRRS don't support hotplug, there's no safe way to reorder the pins so just power off the keyboard beforehand.

RGB LEDs

You need different LEDs for different versions (you have to solder ambient LEDs first, they use the same strip):

  • Jorne V2.1: all leds are the same SK6812-MINI, you need 56 (12 ambient + 44 per-key).
  • Jorne V3: 2 types of LEDs: 12 WS2812B (ambient) + 44 SK6812MINI-E (per-key)

LEDs are chained, order can't be skipped without a jumper wire. Jorne adds LED 28 on the pinky key, LED mapping:

Use 220-230C for soldering or you overheat and kill the LEDs. Educational video:

There are also reverse mount SK6812MINI-E (with E) - they are easier to solder but they won't work on Jorne 2.x. You WILL however need them for Jorne V3 (the version with two non-symmetrical PCBs laid out on a single sheet). Also Jorne V3 needs large planar 2812B LEDs for backlighting.

SK6812MINI

Jorne V2.1 only. Note reversible PCBs are much cheaper than 2 different PCBs for V3.

  • SK6812 3535 BL 3.5mm LEDs, 12 (6 per half) for ambient, 56 for full RGB ($9.74 for 100 pcs)

SK6812MINI pinout is different from WS2812, it's rotated by 90 and pins don't reach the pads in this position. Here's how SK6812MINI looks on a WS2812 footprint (flipped to see the pads):

image

SK6812MINI-E

SK6812MINI-E is much closer to WS2812B than SK6812MINI, the pinout is the same, there's no 90 degree rotation.

Jorne V3-only (version with 2 different PCBs, left and right, laid out on a large sheet).

  • SK6812MINI-E Reverse-mount LEDs for switches, need 44 (Jorne V3 only)

You may also use SK68128MINI-E to replace large WS2812s but you'd need a lot of solder because there's about 1 mm gap from the pins to the board (or just bend the legs):

image

WS2812B

  • WS2812B large 5mm LEDs for ambient, need 12 (Jorne V3 only)

Don't overheat top-mount WS2812 if you're using a fan either, or you end up with something like this (it still works, but it doesn't look too well, maybe just use an iron, pins stick out a little bit).

image

Use brackets on the PCB to determine the LED key position:

1_dyQd48yS4ZIOwrYtzsgOBQ

Note that old LEDs with a large chip may light up if there's no data so better buy new ones (video):

PCB Manufacturers

JLCPCB

Upload the selected gerber file, 5 pcs, black mask, default settings for the rest (FR4, 1.6 mm, 1 oz).

Costed $13.15 total for 5 pcs ($4.00 PCB + $4.80 fee + $8.73 shipping - $5 coupon) in late 2019 ($9.88 in early 2019).

Costed $13.96 total for 5 pcs ($4.00 PCB + $4.70 fee + $10.26 shipping - $5 coupon) in late 2019.

Costs 13.50 + $14.98 for shipping for 5 pcs. Also they ask for extra money: "The order info shows that there is one design, but actually, there are 2 different designs in your file". Note you will need reverse mount MINI-E LEDs for this one (and WS2812B for backlighting).

You may select panel by customer, 2 designs so you will be charged extra $4 automatically without emailing back and forth (Feb 2021):

It's cheaper to order 10 reversible PCBs (2.1) than 5 paired ones (Feb 2021):

5 reversible PCBs cost just $9:

Issues

Since Mar 9 2021 they ocassionally want charge extra $6 for "3 designs", depending of the reviewer:

Don't pay them! Say there's one design, and they need to look once more, it usually helps. They can't charge money if there are common connections between segments.

FR4 plates

You can also order FR4 top and bottom plates in the same order, it's probably the cheapest way to make a hotswap version (ambient won't be as bright as with acrylic but still shines through the sides).

WARNING. As of 14 May 2020, JLCPCB occasionally fails audit on FR4 top plates ("Hi Sir , please kindly note the space between with slot need 3mm at least , thanks"). They complain about these connections:

Note if you cancel the order you lose the shipping coupons "So sorry to bother you, if the coupon was canceled, we can't refund it".

To fix that, they suggest attaching a note "please process my order with the connection less than 3mm, i will not make the complaint if there are any problem after it finish" in the PCB ordering form before putting it into the basket. I just asked them to proceed by email and it worked but it's better to attach the note beforehand.

Plated cutouts

You can modify the plate to make plated cutouts for switches using JLCPCB, if you convert them to oval slots.

Plated cutouts are much more durable than exposed FR4 and generally look nicer.

It's been confirmed a few times that it works with JLCPCB. You'd still have to break off the tabs though.

Upd. It doesn't work anymore. They want slots to be 6 mm max, it's 13 mm. They don't even want to charge extra.

AllPCB

Makes aluminum plates for cheap ($1.7 a pcs plus shippping). Read more about aluminum PCBs here: https://www.allpcb.com/pcb/aluminum_substrate.html

New! You can now order aliminum plates on JLCPCB!

It's the very same material keeb.io used in nyquist plates. They are NOT REVERSIBLE so you'd have to order left and right plates separately (they are 1.5mm raw aluminum on one side and 0.1mm dielectric layer with copper and mask on the other side). I only have design files for the FR4 substrate so you'd have to do the aluminum version yourself.

Factory-made Cases

If you break extra keys off you get 100% original Corne, then it can use Corne cases from these manufacturers:

It's also fully firmware-compatible with the original Crkbd (the extra key is on the thumb row so it doesn't change the matrix).

Kunai

The Kunai - Corne Case, Ergonomic Corne case designed to work with acrylic and FR4 Cornes plates by mell0w.

20230625_160027

There's an also an open source attempt to fix the (severely broken) Kunai:

The original model is a great design, thank you for mell0w's design sharing. However, there are many broken surfaces. Some of the broken surfaces, especially the large gap at the top, have been repaired based on the original model.

Chinese case

There's a Kunai-shaped closed source case sold by Xianyu (Taobao second hand market) user @wellxx. If you know where to get a model of that case, let me know. I'm not quite sure what case was first this one or Kunai, because these posts are more recent than the Kunai publishing date.

Nusumu is a new case, made from scratch, with Kunai used as an inspiration. The model is free and the shape and the topology is better than Kunai.

Tilting/Tenting

What is tilting/tenting (from https://docs.splitkb.com/hc/en-us/articles/360019770320-What-are-tenting-and-tilting-):

tilting-tenting

I do NOT recommend tiliting/tinting acrylic cases, they are prone to cracking. If you want to try them you'll need more screws:

3mm acrylic case, M2 countersink screws and 6mm standoffs, tenting made of M5 screws (2x30mm and 2x16mm).

jorne-tenting

You may use Chicago screws to lay the case flat (screws are M5x10 mm, acrylic case 3 mm):
