Pic based electronics.
by volunteerlabrat, published
I have designed my own reprap electronics based on a PIC18F2620 micro controller and A3982 stepper drivers.
It has been designed to be as cheap as possible. If you can etch the board yourself it should cost no more than 40 euro (55 usd) to build.
It all fits onto a 160x100 eurocard sized PCB and is currently running on two repraps.
I am happy to share the firmware source and the PCB layout. As for now however I'd like to run more tests with it before I release it.
Why not share it now? Take just a week before posting this. I was forced to solder some capacitors to the rear side of the PCB to remove EMF. I have yet to add those to the schematic.
