[Nothinglabs] built this motor controller as an alternative to using an H-bridge. They call it the RAT controller which stands for “Relay and Transistors”. You can see above that two Darlington ...
The BA6920FP-Y is a DC brush motor driver. The device is a reversible motor driver in which the output could be set to four modes: normal, reverse, stop (idling), and braking respectively, in ...
With these mods, this circuit will last quite a long time, especially if you make things easier for the relay by turning off power to the motor before switching directions. It is simple and effective ...
