Just thought I would say I successfully got the boards made from seeedstudio.

I had one mistake, the diode silkscreen (maybe also in the schematic? - I should check...) is backwards. I discovered...

Okay updated the schematic to be for the 3.3v. (I assumed those resisters are in series)

3814

3815

3816

are the two 47ohm resisters in parallel or series?

Is the midi in 270 ohm resister the one on pin4 of the PC900?

Going to be a teensy 3.1 (it's so I can do work with the audio shield)

I guess I should add room for the two resistors on the midi out.

Room for a dip switch might be cute.

Okay I made the suggested changes (I think) annular rings should be bigger. I removed the 'extra pins' connectors which just added complexity. I sent the midi in shield to NC.

I also fixed a...

I thought the shield was supposed to be connected to ground?



Thanks, I'll look into it.



Good call didn't think of that!

Hello,

I'm making a stab at building my first PCB using GEDA. It's a copy of the schematic PJRC posted https://www.pjrc.com/teensy/td_libs_MIDI_sch.gif
so I can start mucking around with the...
