KiCAD based A10 break out / prototyping PCB is finished.
This is a 6 layer A10 prototyping / break out board with all the pins
except ground lines brought out to pads from where it can be wired to
make any kind of device.
The Gerbers are included, but you can modify and generate your own from
KiCAD. If you build and try to use it, the ground at the back needs a
direct connection with a thick wire as there is not enough ways to get
fat tracks into that region with this arrangement of wiring.
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.
