PowerBoost Connections

Grab the bottom half of the enclosure and sit the PowerBoost 1000C on top of the four standoffs near the bottom left. Then, insert the slide switch into the bottom center. These two components should just snap fit into the case.

Next, we need to measure two 26AWG wires for connecting the slide switch. They'll be connected to the EN and GND pins on the PowerBoost 1000C. Once you've sorted out a good length for them, strip and tin the ends of each wire.

Prep Slide Switch

Now that we have our wires sorted out, we can prep the slide switch. First, we don't need three leads, so remove one using a pair of flush snips (it can be any of the leads on the far left or right, but not the middle). Then, trim the remaining two leads to about half their length. Now we can tin them by applying some solder.

Solder Wires to Slide Switch

With the leads tinned, solder both wires to the two leads. Pieces of shrink tubing will insulate the exposed connections. Simply apply heat to "shrink" the tubing.

Connect Switch to PowerBoost 1000C

Solder one wire to the EN pin on the PowerBoost 1000C and the other to GND.

Now you can plug in the JST connector from the 2000mAh battery into the JST port on the PowerBoost 1000C. The switch will allow you to power it on and off. The blue LED will light up indicating it's powered on.

Photos show a PowerBoost 500C, but you should use a 1000C. Pinouts are different, so read the pin labels on the PCB, don’t just follow the photos.

PowerBoost Wires 

Next, we need to sort out a set of two 26AWG wires for connecting the PowerBoost 1000C to the Raspberry Pi Zero. We can do this like we did for the slide switch. 

Once we have a good length, cut, strip and tin the wires. Then, solder them to the postive+ and negative+ pads on the PowerBoost 1000C.

Connect PowerBoost to Raspberry Pi

Now we can solder the positive and negative connections from the PowerBoost 1000C to the GPIO pins on the back of the Raspberry Pi Zero. Reference the photo for the right pins. Red is positive, and blue is negative.
