Assembly of the Bluefruit TV Zapper is plug-and-play, thanks to the 3-pin STEMMA port and alligator clip cable.
The first step here is optional -- if you want to snap the Circuit Playground Bluefruit into the case, go ahead and do so now, before connecting the alligator clips.
Connect the alligator clips to the following pins on the Circuit Playground Bluefruit:
- black to GND
- red to 3.3V
- white to A2
If using AAA x3 battery pack, plug the battery pack's 2-pin JST connector into the power port on the Circuit Playground Bluefruit.
If using a LiPo battery, plug its 2-pin JST connector into the power port on the Circuit Playground Bluefruit.
You can use the BLE TV Zapper as is -- which may be easier to hide in a drawer with just the IR LEDs peeking out -- or make the package a bit more compact with some adhesive squares.
Attach the battery to the case first, then attach the IR breakout as shown here.
