Prepare your battery pack

If your battery pack doesn't have a 2.1mm DC jack attached already, you'll need to add one. 

Three AA alkaline batteries are recommended to power CRICKIT. Alkaline batteries have a 1.5V max voltage, so 3 of them in series provides a steady 4.5V output. Perfect for CRICKIT! 

If your battery pack already has a DC jack attached, you can skip this step.

Remove batteries before hacking on your battery pack! Snip the JST connector off your battery pack. We won't be needing this.


Strip about 1/4" insulation off the end of the red and black wires.


Screw these wires into DC terminal block.


OPTIONAL: Peel back and remove the belt clip from back of the battery pack. This will make it easier to mount into your box.

Attach Servos

Connect servos to your CRICKIT board. 


Be sure the yellow wire faces the edge of the CRICKIT board and the brown/black wire faces the Circuit Playground Express.


Connect your DC plug to the power jack on your CRICKIT board.


Use double sided tape to stick your battery pack to the inside of the box and CRICKIT on top of that.


Connect Circuit Playground Express to your computer with micro USB cable.


Make sure the battery pack and Crickit switches are set to "ON"!

Once everything is connected you're ready to move on to The Code!

Let's stumble onwards!
