I have 8 complete kits for the I/O board available here. These include all parts needed to build your own IO board, for $18. I will be posting a guide shortly to help out with some of the trickier bits. If you’ve assembled PCBs before this should be easy enough, but if you don’t have much soldering experience I suggest finding a modder to assemble this for you (I can ship direct to them if you put in their address, talk to them first) or look for a pre-assembled board from another seller.
RAM kits coming soon!
