Hello everyone,
I am trying to design a low cost open source programmable guitar/microphone effect pedal with my Teensy 4.0 + Audio Shield.
I have tested the circuit on breadboard (Except the mic phantom power) with a vocoder effect and it worked fine except some noise that i expect to disappear on the actual circuit.
The EAGLE for the PCB are on my github:
https://github.com/VasileiosVasilopoulos/GuitarPedalPcbs/tree/master/DeepSpace
The complete PCB fits in a 1590BB enclosure.
I am currently soldering the PCB in order to test it.
I would like to ask a question: My teensy is soldered with the Audio shield and i do not have a desoldering station at the moment.
Can i power the Teensy over USB to flash the code, and then power over the +5V from the PCB as long as i don't do them simultaneously?
(Without cutting the trace on teensy)
Also does anyone have any suggestions to improve the pcb? Any obvious mistakes?
