Description
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]

Questions
How big is the Sbc PCB?
It measures 60 × 40 mm and has 4 copper layers, 0.99 mm thick.
What parts does the Sbc use?
119 parts, built around the MT48LC16M16A2P-6A:G, AT91SAM9G20-CU, USBLC6-2P6 and BSS84. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Sbc KiCad files?
From the Gidronaft/tst repository on GitHub, at the commit this page was made from: the board is sbc.kicad_pcb and its schematic cpu.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sbc design in my own project?
Its repository states no licence, so its author keeps all rights: ask Gidronaft before reusing the design.
