I have question about the exposed pins on this shield.
For example, in the Board Overview section, what does “D6 + -” mean.
I assume D6 is for pin D6 on the arduino. What is the “+” and “-” pins. My guess is that is power / ground?

Sorry for the late response. "D6" refers to pin D6 on the Arduino board, which is a digital input/output pin. "+/-" represents the power pins on the module. Typically, the "+/-" pins are used to connect the power and ground (GND).

I tested this out and the “+” and “-” do appear to represent power and ground respectively.
