IR LED Power Distribution Box

by iCON

A 3D printed IR LED power distribution box that houses current limiting resistors, micro USB input power connector and an optional integrated power switch. Includes terminals for wiring an external power switch and a power indicator LED (since you can’t see infrared light!). Wire connections are made using screw down terminals, zip-tie strain relief keeps the wires from pulling out. The cover snap fits into the box and holds the PCB in place without any screws.

The author marked this model as their own original creation.

Micro USB Breakout Board
Quantity: 1 (Required)

Supply 5v power to infrared LEDs


Prototype PCB: 2x8cm, 2.54mm 0.1″ pitch
Quantity: 1 (Required)

PC board that you solder your resistors, breakout board, connectors, etc. to


Resistor: 6.8 to 10.0 ohm, 1/4 watt
Quantity: 4 (Required)

Limits current through each IR LED assembly. The lower the resistance value, the more current will flow and the brighter infrared light. Just make sure your IR LEDs do not get hot, if so use a higher resistance value. The length and gauge of the wire used to connect the IR LED assemblies will have an affect on the amount of current that flows. Choose 1% tolerance if available, otherwise 5% will also work. In my experience, 8.2 ohm resistors will result in 100mA of current through 3 OSRAM IR LEDs but YMMV.


Resistor: 500 ohm to 50k ohm
Quantity: 1 (Optional)

Limits current and brightness of the indicator LED. If you are not using an indicator LED this part can be omitted. Before assembling the IR Power Distribution box, test your indicator LED brightness with different resistor values until the desired brightness is achieved. You should test brightness in a dark room if that is how you will be playing most of the time.


Rocker Switch
Quantity: 1 (Optional)

Use this switch when building a power distribution box with an internal switch. If using an external switch, any on/off switch will work.


Screw Terminals: 2 pin, 2.54mm 0.1″ pitch
Quantity: 6 (Required)


Solid copper wire: 22 gauge
Quantity: 1 (Required)

Used to connect components on the prototype board. Stranded wire will also work but is a little more difficult to use as a jumper.


Zip Ties: 4 inch / 10cm
Quantity: 6 (Required)

Keeps wires from pulling out of the screw terminals
