This is a pretty well spec'd power distribution board for multirotors (quadcopters or tricopters) from Volo. It contains two voltage regulators (UBECS), reverse polarity protection, LEDs to indicate that the outputs are functioning within acceptable limits and a 4-layer PCB for maximum current handling. The conformal coating also makes this board highly resistant to high levels of humidity or even direct water splashes.
I put it through its paces and it works exactly as advertised.
My only criticism would be the inability to switch the 6V output to 5V in order to support any devices (such as older Naze32 boards and helicopter tail-rotor servos which aren't rated for 6V operation.
