We're comparing different single board computers, the BeagleBone Black and ODROID-C2, as these are most wide-spread, have the largest communities and offer most features and power for the price.
Conclusion so far: For the CCGX to run, both the ODROID-C2 and the BeagleBone Black could be used.
Both are very similar in cost, for the BBB a USB hub must be added, for the ODROID-C2 a CAN controller.
The BBB has 1 clear advantages over the ODROID-C2 for this application:
- 4x UART
The BBB sports 2 PRU's, that are like seperate 32bit µC's that can be used for real-time control.: PRU's
Comparison table
| Feature | BeagleBone Black | ODROID-C2 |
|---|---|---|
| USB | 1USB (Hub needed $2.50?) | 4USB (Internal hub, GL852) |
| Storage | Onboard storage 4GB flash. eMMC flash is as fast as class 10 SD cards. Also microSD | Onboard EMMC and microSD slot (simultaneous use possible) |
| UART | 4 freely available UARTS and 1 for console. CAN bus on SOC. Performance should be way better that an external SPI CAN. Needs transceiver just as with Rpi. | 2 UART freely available via GPIO header, 1 additional UART for console |
| LAN | 100Mbit LAN | 1000Mbit LAN |
| GPIO | 65 GPIO | 40GPIO |
| Open-source | Open source hardware | Schematics/datasheet available |
| Power consumption | Lower when idle (300...500mA) | ? |
| Quantity sold | 0.25mln pcs sold | ? |
| RAM | 512MB RAM | 2GB RAM |
| GPIO Expansion | over 100 “capes” available (DCAN, RS485, USB.) Not all open source. | Please note that pins #37, #38 and #40 are not compatible with Raspberry Pi B+ 40pin header. |
| LCD | (touch) LCD Addon available" | ? |
| Price | $55 | $40 |
| VE.bus | VE.bus via MKIII (like CCGX) (Needs UART) | ? |
| PMIC | Internal PMIC can handle safe shutdown in case of power failure. Prevention of Flash corruption should be done in the file system | Yes, additionally a (UPS with build-in LiPo available from manufacturer for $49) |
| Additional µC | 2 PRU’s (µC's for real time applications) | ? |
| RTC battery | No | Yes |
| Datasheet | available | available |
2016-06-10: added some more intesting boards:
- vibe and vibe2 Indian company making a AM335x Sitara ARM Cortex-A8 processor based board with lots of IO, including 2G /3G (!) etc.
- C.H.I.P. -> Allwinned based 9 USD board including Wifi and BLE.
