Just realised that when I bought my pixelblaze for some reason I ordered two boards but only one sensor board. I’ve left it too late to order a second sensor board before my event. I can’t share the audio data between them as they will be in use on different stages.
Any way I can attach a digital mic directly to the main board or is my only option to have second micro controller with the mic and try and output the serial data as if i were the official sensor board. If so is the FFT and mic related code somewhere public and in a form that would work on something like an ESP32?
