PCB input board and case design Posted on March 12, 2013
A friend of mine can build PCBs for me, so I designed one for my input board with five MCP23017 port-expander and three HCT4051 multiplexer. Here is my design made with fritzing:
fritzing files on github (also created fritzing objects for MCP23017 and HCT4051)
I also printed my case design and bought wood to build it. The final order of turn-potentiometer, push-buttons and ic-sockets for the input PCB has also arrived. So it is just up to me to start building the final controller.
