Assembly of the Bluefruit TV Zapper is plug-and-play, thanks to the 3-pin STEMMA port and alligator clip cable.

Case

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.

Cable

Next, plug the JST 3-pin 2mm cable into the IR Emitter board.

Connections

Connect the alligator clips to the following pins on the Circuit Playground Bluefruit:

  • black to GND
  • red to 3.3V
  • white to A2

Battery

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.

Stack It

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.
