Holybro Power Distribution Board with Integrated UBEC and OSD (V1.1)
The Holybro PDB has been designed with the FPV drone enthusiast in mind. It is not just a PDB but comes with a 5V UBEC integrated into the board. The UBEC can be used to power up the flight controller, camera and video transmitter. All power outlets are conveniently positioned for ease of use.
There is even more with a built-in OSD, which comes with MWOSD firmware already loaded. This provides critical information (such as battery voltage), via the VTx, direct to your goggles or monitor.
This is a great package for FPV drone racers as it is built onto a board that easily stacks below your FC on most racing drones.

Seems to be a good PDB for quadcopter. Supplied cables and power connectors suited Pixfalcon without any modification.
There's solder pads to join ESC inputs and server outputs from a flight controller, keeps wiring reasonably tidy, especially for a pixfalcon.
Current and voltage sensors calibrated OK with normal arducopter proceedures.
There's 5Vdc , 0v and vid-in and vid-out solder pads on the underside for the OSD.
The OSD can be programmed with a USB FTDI (5volts) but pay close attention to connections.
The OSD worked for a while after I updated the firmware, but has now stopped for some unknown reason.
I got the updated OSD firmware from:
