Nice PDB with some well thought out features. BUT ...
For CleanHawk 250 Quadcopter Power Distribution Board
CONS:
Top of board: Spacing and size of ESC solder through holes are really poor. There's little soldering room to keep wires a "healthy" distance apart and the ESC power pads could do with being a LOT larger diameter with more copper around the periphery to make soldering more durable - as could the signal and ground pads... space them out more and make them larger. I resorted to having to use a multimeter to check for shorts - as these pads are so close to each other...
Bottom of board: Exposed solder joints and surface mount LEDS - seriously, why?Are ALL open to the elements and contact with nice wet shorting grass... and rocks and stuff... so either 3D print yourself some sort of transparent guard or just coat the entire underside in something like liquid electrical tape to help prevent damage to this pcb.
PROS:
PDB neatens and tidies wiring. Onboard BEC.
