Other Extensions: control of direction indicators, the logic part of the plate to take power interface.
An external transistor or mosfet is a best choice to drive a 12 volt motor using stm32 microcontroller. The six-channel Micro Maestro raises the performance bar for serial servo controllers with features such as a native USB interface and internal scripting control. The L298N driver module, using ST’ L298N chip, can directly drive two 3-30V DC motor, and provide a 5V output interface, power for 5V single-chip circuitry, support 3.3VMCU control. Transistor or Mosfet as external circuit to drive, control the speed and direction of DC motor.
