![]() This bridge chip is an 8 DIP package so it's easy to fit onto any breadboard or perfboard. Basically, the p-type MOSFETS go in the upper side of the circuit and the n-channel go at the bottom. If Switch 1 and 4 are closed, then the current will flow from the left to right on this image: Full H-bridge circuits capable of a few Amps can be purchased in convenient IC packages (see PWM and H Program example: Switching the direction of rotation with H-bridge. Because switching the wrong thing at the wrong time could cause a short circuit, the switches of an H-bridge are generally controlled by internal circuitry, and driven by two logic pins. MicroPython is available also for STM32F4xx (STM32F4-DISCOVERY), see here. With MicorPython user can write clean and simple Python code to control hardware. I aim at reducing the size and weight of the board as much as I can, so I implemented this design so that the input signals are from an arduino uno.
