Anyone know what this is?

This arrived in the post with a pixhawk 2.4.8 I just ordered.

I didn’t order it and I have no idea what it is. There are no markings on it except what you can see.

Anyone know what it is or what it’s for?


it could be a dual brushed ESC. If you remove the heatshrink, it might be easier to identify the part.

Heatshrink removed

One of the leads would have to have 3 wires for it to be an ESC wouldn’t it?

It looks like a voltage regulator. But the adjustable potentiometer has been replaced with a fixed resistor.

Connect the side that says in to a battery and measure the output.

You’re correct. It appears it’s a DC - DC Stepdown converter with connectors that do not fit into the pixhawk anywhere. Useless to me. Oh well.
