The SoM2 board has been updated to make a break out prototyping PCB.
This is work in progress for anyone wanting to take it and improve on
it. The design takes on board contributions about pinouts for the A10,
and also Luke's KiCAD files about A10. Luke's footprint for A10 has
Please check it and give feedback to repair mistakes.
The design should fit on a 4 layer board - but as I say its work in
progress for anyone wishing to improve on it.
The aim of the board is to allow a slow speed operation of the A10 as a
standard microprocessor with some 400 GPIO pins to hand. Many items such
as SDCard, real time clock, RS232, and LCD should work
at low speeds if you were to add it on by connecting it from a
breadboard to this board. Linux won't run without a lot of RAM, so you
may be able to wire something up and run
it at low speeds if you plan running Linux from say the SDCard.
(A future derivative will have the RAM chips to eliminate the wiring.)
An ideal situation is to get something to boot from SDCard and flash a
simple LED. Providing that part is fully documented, the software
together with this board becomes a useful stepping stone to
learn to build more complex derivative projects like the EOMA.
