Drone power distribution board open source

Power distribution board design:
The output current of our power distribution board is mainly divided into 4 parts.
The first part is the battery power output:
Since the current output to each motor on the voltage board, the current output for the 12v voltage conversion, the 5v voltage conversion, and the 19-24v voltage part are in parallel, we directly use two layers of PCB to conduct the current.
The second part is the 5v voltage conversion
to convert the voltage of the 4s aircraft model battery to 5v voltage. We use the MP1584EN chip solution for voltage output.
(To be supplemented)
The third part is the 12v voltage conversion
to convert the voltage of the 4s aircraft model battery to 12v voltage. We use the MP1584EN chip solution for voltage output.
(To be supplemented)
The fourth part is the 12v voltage conversion
to convert the voltage of the 4s aircraft model battery to 19-24v voltage. We use the LM5122MHX chip solution for voltage output.
