on the UBEC, where the wires are already attached.

Connecting the UBEC to the Raspberry Pi in order to

supply power will be covered in the next step.

>STEP-03

Powering the Raspberry Pi

In order to supply power to the Raspberry Pi Zero,

the UBEC can be connected to your Pi in two different

ways: either by soldering the connections directly

to the GPIO, or by attaching the three-pin socket on

the UBEC to the Pi via a pre-soldered header. The

photos show the output wires from the UBEC soldered

directly onto the Pi’s 5V and GND pins (pins number 2

and 6). Alternatively, you could solder a GPIO header

onto the Pi and simply plug the UBEC’s three-pin

socket into the GPIO header – pins 2, 4, and 6 –

making sure the black wire is connected to pin 6.

>STEP-04

Connect the power circuit

The two input leads of the UBEC should be screwed

into the corresponding terminals on the female barrel

jack adapter, as well as two jumper wires connected to

the correct terminals on the male barrel jack adapter.

Using a hot glue gun, the female barrel jack socket can

be attached to the hole that was drilled in the rear of

the casing. Secondly, the UBEC can be attached to the

inside of the casing in the same way. Finally, the male

barrel jack adapter can be attached to the opposite

side of the casing as the UBEC (see photos) to later be

attached to the infrared illuminator.

>STEP-05

Mount the IR illuminator

Using a few small dots of hot glue, the infrared

illuminator can be fixed to top of the case’s lid, as
