This can take 120v input and convert it down to 28v or as low as 2v @ 1.5A. Typically used to power 12v or 5v LED strips, it has an enable line that plugs into the 5v header of the lilfoccer right next to the CAN connector. This will automatically turn on the output when the lilfoccer turns on. It is delivered with the voltage potentiometer turned all the way down so you will need to solder on your preferred high voltage input and output connectors and apply power to the input and then give it 5v via the enable line and tune the potentiometer to your desired output voltage. There is a screw hole for mounting via an m2 screw, and our V1 flowglider mod print has 2 spots for these. We recommend using 388 silicone underneath the pcb during install as well as against the caps, resistor, wires, and inductor after install for vibration resistance.
