Description
Mini H-Bridge motor control
This is a mini H-Bridge.
The S8050 and S8550 are PNP, and NPN transistors to change the direction of the motor. They use the 550ohm, or similar, resistors.
The two BC546 transistors are used to make the inverters. They have the 10k and the 1k resistors. These are the ones at the bottom of the board.
