Let me start by saying that I am a long time user of this board. I have chained 6 of them to control a bunch of step motors in a robotic application.
However I just saw that you have created a new version now (v13). I have a suggestion for the next version and that is to please consider either selling a potentiometer that fits into the footprint or sell the board pre-mounted with the potentiometer. Controlling current is crucial and I don’t understand why the potentiometer is not there by default.

I am new to step motors and this board seems like a good option to start with.
I have two questions and I am hoping for some help here.
How should switch be activated, is it suppose to be set to 5v or 0V in order to activate a stop? I plan to connect HOME_REF_PIN to the board and I don’t know if I should connect it to 5V or 0V in order to activate a stop.
AutoDriver boardA(10, 6);
#define HOME_REF_PIN 4
Serial.println("Finding home reference...");
boardA.goUntil(RESET_ABSPOS, FWD, 50);
long currentPos = boardA.getPos();
Serial.print("Current position (should be zero) ");
Stall Detection is mentioned in the product description, but I can not find any proper references to in the git repository. How should stall be detected and handled? Can someone provide an example please?

Is it possible to connect a “Electret Microphone Breakout” such as https://www.sparkfun.com/products/9964 directly to this board? (I would like to skip the left/right input audio cables)
I don’t want to have a long audio cable coming to this shield. Does anyone know if I can directly connect the Audio-signal from “Electret Microphone Breakout” https://www.sparkfun.com/products/9964 to both the Right and Left of this shield?
No public wish lists :(
