Amos Joseph’s MIDI Shield is a project we’ve mentioned before, as a prototype. Well, he got his test PCBs back from BatchPCB and overall is happy with them. There are a few things he wants to change before producing a larger batch:
MIDI requires the use of the Arduino serial port pins, which are also used by the on-board USB programmer. With my current design the MIDI Shield has to be unplugged before the Arduino can be programmed, which is a pain in the ass. Instead, I’m going to add a jumper to the MIDI Shield. Remove the jumper, program the Arduino, then put the jumper back on. Much better than pulling the whole shield off every time you need to upload code.
