Wiring BLE Feather
Next we’ll wire up the Adafruit Feather. I used a stick vise to secure the PCB while soldering wires.
Solder JST Cable
We’ll solder the JST cable female to ground, voltage and any of the available data pins. In this project, the code is set to Pin #6. If you decide to change this, you will need to reflect that in the code.
