RaspberryPiAdapter Board

Abstract

The Raspberry Pi is very popular and you can barely get around it. That is why I build an adapter board that can be used to connect the different boards together, including the Raspberry Pi, to form a full console. I made it to be very flexible. It has an ICE40 FPGA, for those who have a Raspberry Pi 1..3, with only one serial port or would like to have the FPGA do the DMX512/RDM transfers or would like to connect 8 DMX512/RDM level shifters to the Raspberry Pi. Those who would like to use the UARTs or the Raspberry Pi4, can leave the FPGA unpopulated and place other 0R resistors. This board is work in progress and thus is not complete. For example the 1.2V for the ICE40 is completely missing.
