The follow-up to my previous SBC based on AT91SAM9260, enhancing the board specs in computing power and flexibility. The board is smaller 60x40mm now (SAM9260 was 80x40mm) while keeping the same amount of supported RAM and interfaces. AT91SAM9G20 boosts core speed to 400MHz and bus speed to 133MHz.
Board overview (draft): [TBD]
| Characteristic | Description |
