This is the BabyPDB, a 36x36mm (30.5mm hole spacing) power distribution board with an integrated current sensor and selectable 5/6/8/12V 3A Switching BEC.
The board has 4 voltage output pads large enough to allow for easy soldering of ESC power wires and 2 large input voltage pads for big gauge wires from the battery.
The built in current sensor is great for logging how much power your copter is drawing, but much more interesting is the monitoring of mAh drawn out of the battery. To me this is huge. It allows for a much more accurate way of knowing how much juice is left in your battery. This information can easily be relayed through telemetry to your RC transmitter together with the real time current draw. Just hook up the Isense pad to the appropriate analog input pad on your Flight Controller.
The built in BEC is of the switching type, meaning it’s super efficient and can deliver up to 3A. The output voltage is also easily set to either 5V, 6V, 8V or 12V by bridging 4 different solder pads. The board can easily power 50 5V RGB LED’s without breaking much of a sweat, or you can power FPV gear, servos, charging a GoPro or what ever you fancy.
To make wiring as simple as possible, the board has easily accessible pads for Isense, Vbat out, BEC and ground.
In cleanflight/betaflight use current scale 360 to get the correct current value.
