The “Power Distribution” is the electronic board that takes the battery power as input and distributes it to the various modules of the robot. The components of the board are sized to be connected to the Lipo 4S 30C battery and is protected by power inversion and by power spikes thanks to an automotive 15A fuse and a 1.5KE18A Transil. The power is filtered by a 3rd order Pi Filter in order to decouple the powering of the motors by the powering of the logic modules.
The PCB of the board is made on two layers, the top layer is the power distribution plane, the bottom layer is the ground plane and soldering plane.
The circuit is not too much complicated, but the PCB has been studied such to decrease any potential rising of the temperature and to eliminate potential noises.
The CLC filter is designed to support continously assorbtions up to 10A, enough to connect the logic modules that are mounted on MyzharBot.
