Hi,<br>
<br>
KiCAD based A10 break out / prototyping PCB is finished.<br>
<br>
This is a 6 layer A10 prototyping / break out board with all the pins<br>
except ground lines brought out to pads from where it can be wired to<br>
make any kind of device.<br></blockquote><div><br>Great work. Would it be better to have the power supply controller, like AXP209, also onboard. In fact I do not whether we can power A10 without something like that.<br><br>

The Gerbers are included, but you can modify and generate your own from<br>
KiCAD. If you build and try to use it, the ground at the back needs a<br>
direct connection with a thick wire as there is not enough ways to get<br>
fat tracks into that region with this arrangement of wiring.<br>
<br>
The aim of the board is to allow a slow speed operation of the A10 as a<br>
standard microprocessor with some 400 GPIO pins to hand. Many items such<br>
as SDCard, real time clock, RS232, and LCD should work<br>
at low speeds if you were to add it on by connecting it from a<br>
breadboard to this board.<br>
Linux won't run without a lot of RAM, so you may be able to wire<br>
something up and run<br>
it at low speeds if you plan running Linux from say the SDCard.<br>
(A future derivative will have the RAM chips to eliminate the wiring.)<br>
<br>
An ideal situation is to get something to boot from SDCard and flash a<br>
simple LED. Providing that part is fully documented, the software<br>
together with this board becomes a useful stepping stone to<br>
learn to build more complex derivative projects.<br>
