Schematics
The ESC center board contains all four Electronic Speed Control circuits of the quadcopter. Flight controller (also called Main Controller) is placed on a separate board, soldered at the top of the ESC center board. In P3C, the radio receiver board is soldered on the ESC center board too. This board also acts as a relay for connectors which link all other modules to the Flight Controller.
There are multiple versions of the board.
