This is a small switching power supply rated for up to 3A. We recommend keeping it under 1.8A without reasonable cooling.  It has an adjustable voltage level so will handle the usual 3.3v, 5v, 6v, 12v etc required to power your flight controller, receiver, camera and VTX.  

This is ideal for mini fpv rotors running 4S and opto ESCs.  It is not recommended for planes, please see the ZTW - 6A UBEC for this.  

We have included a free 220 electrolytic capacitor which will reduce ripple by at least half. It is not required, however, for noise sensitive applications, it may be useful.  Solder the longer wire to the positive output and the shorter wire to the negative output. Keep wire as short as possible and cut any excess.
