Circuit Diagram

 

The 2-pin JST cable from the battery connects directly into battery port on the PowerBoost 1000C. Voltage and Ground wires from the PowerBoost 1000C connect to the 3-pin JST port on the PyPortal (doesn't matter which one).

  • 5V/VCC pin from PowerBoost 1000C to 3-pin JST(VCC) on PyPortal
  • GND from PowerBoost 1000C to 3-pin JST(GND) on PyPortal
  • EN from PowerBoost 1000C to switch
  • GND from PowerBoost 100C to switch

Slide Switch

Use a 2-wire cable (110mm long) to connect the slide switch to the PowerBoost. Remove a bit of insulation from the tips of the wire and tin them with a bit of solder. Connect the wires to the middle pin and either the far left or right pin on the switch. A third helping hand tool can hold the switch and wire in place while soldering.

Connect JST Cable

We'll use a 3-pin JST cable (9cm long) to easily connect the PowerBoost to the PyPortal. We only need two of the three wires, so you can remove the white wire. Using wire strippers, remove a bit of insulation from the tips of the wire and tin them with a bit of solder. Solder the wires to the voltage (+) and ground (–) pins on the USB output of the PowerBoost.
