A 36x36mm sized PDB with some extra goodies on board. Firstly is the BEC (battery eliminator circuit). It is actually two BECs in one, delivering both 5 and 12 volt outputs for powering your flight controller, camera, gimbal or other components that require specific regulated voltages. Another fun feature is the LED output. You can choose from steady on, or two different flash rates (1Hz and 3Hz). The flash state can be changed by pressing the momentary switch on the PDB or via your transmitter. Next on the list is the low voltage alarm. It can monitor 2s - 6s lipos and will alert you when the pack has been discharged to your specified voltage. Finally, a built in circuit to help you find your lost aircraft. When activated the LEDs and beeper will flash/beep at 2Hz to assist you in locating your model.
That's pretty much it. A very functional, lightweight PDB with a small footprint.
