MOTOR DRIVER VERY HIGH POWER max 43A
The first and only motor control for Arduino that gives users the ability to control up to 30A of current at up to 28V. That's over 800W of power! At last Arduino users can easily control high-
It is a dual half-
The module is built on 2 nos. BTS7960 .Recent boards use BTN7960 , both are same.
Each BTS7960 chip is only half-
The BTS7960B's got a thermal protection circuit, that's even better than your motors. So if you are lucky your drivers will actually protect your motors if wheels gets locked.
A2630 8pin IC is opto coupler ( optically coupled logic gate that combines a GaAsP light emitting diode and an integrated high gain photo detector). An enable input allows the detector to be strobed. The output of the detector IC is an open collector Schottky-
The opto coupler saves the controlling Microcontroller by isolating it from the high current side.
The small heatsink may need some other cooling technique (e.g. air flow, etc) if you use it for high current applications.
The board has 78M05 regulator chip, with power indicator light.
