- None
- Updated Neotron Common Hardware (the library of symbols and footprints we use) to v2.0.0
- Updated to KiCAD 7.0.11
- Replaced MCP23S17 DIP with SOIC (#176)
- Fixed DAC output resistor (#177)
- Split microphone audio / bias (#132)
- Added more GND vias near power vias
- Minor adjustments to schematic labels
- DNF components now not shown on iBOM
- J901 is a header not a socket
- External LED drive is 5V 20mA
- Moved passives clear away from expansion slot legs
- Updated STEP model
- Added new top-down view to README.
- Set BMC part as being STM32F030K6T6 (F031 is unavailable)
- Switch to DIO2663 video buffer
- Specify THS7316 as default video buffer (TPF133A and DIO2663 should also work)
- Stitching vias for ground planes, and wider traces between vias and pads
- Re-arranged top-sheet
- Two PSU control BJTs are now surface mount
- Support 5V DS1307+ as well as 3.3V MCP7940N Real Time Clock
- Use 200mA Holtek HT7533-1 stand-by regulator
- Swapped MCP23S17 for MCP23S18 (because that's what's available)
- Added internal 12V input header
- Changed inner layers to both be GND
- K7805-3AR3 control pin is protected with a zener (allows higher input voltages)
- HDD LED is driven from I/O mux, not BMC
- Relaid out board
- Replaced 12 MHz Crystal with JLCPCB basic part (#103)
- Replaced SD Card with Amphenol part (#99)
- Redesigned audio paths (#93)
- Replaced decoupling with single 10uF (#92)
- Added PC speaker output (#87)
- Changed K7805-3AR3 to have ceramic output cap (#84)
- Remove all the Octopart CPL references (#83)
- Increased VGA DAC current (#77)
- Replace 74HC245 with 74HC138, plus five LEDS for the now spare pins (#65)
- Added missing I²C pull-ups (#61)
- Change I²S pinout to match Raspberry Pi demo board (#60)
- Pulled CODEC's CS pin (#59)
- Added pull-ups to all SPI CS lines (#58)
- VGA ESD protection chip has bypass pins for when not fitted (#51)
- Case LEDs driven from 12V supply (#46)
- Fixed dead short through PSU Control BJTs (#43)
- Adds 6mm switches for power and reset (#42)
- Added internal 5V/3.3V output header (#41)
- Reverse polarity protection on the input (#40)
- Tweaks to the BOM outputs, including an HTML format BOM
- Revised voltages for each capacitor, specifying the minimum acceptable
- Most parts still specify a component that is better than the minimum, because of availability or price.
- Moved BOOT0 silkscreen
- Moved labels for BMC SWD and UART ports
- Moved some vias near the BMC to improve the ground pour
- Added version numbers to the release outputs
- Added PNG, SVG and STEP releaseoutputs
- Sent to JLCPCB to assembly.
- Note that C901 and C902 part no.s were wrong and were manually fixed before ordering.
- Replaced SIP resistor array for PS/2 ports with four SMD resistors
- Swap fill on bottom layer to be 3.3V not Ground
- Replace RTC with DIP package due to availability
- Increase size of electrolytic capacitor footprint, to better suit size of common parts
- Replaced VGA connector - in-stock ones have the pins set back from the board edge
- Adds via stitching around the edge of the board
- First complete PCB layout
