Robotics

To drive a motor with reverse motion, a circuit with 5 transistors, so called H Bridge. The H-bridge module om market usually support 2 outputs. The logical voltage is usually 3.3V/5V.

When using PWM to drive DC motor, do a high pass (of say 8 out of 255 with 8 bit resolution) on the duty cycle as the motor does not handle low voltage well and will squeak.

Do use a suppression diode to cross the load to protect the transistor from voltage spike.

Brushed motor will have spark, and is cheaper
BLDC = Electronic control unit (ECU) + permanent magnet three phase AC motor; it don't have spark and is lighter and more efficient

GPIO pin does not provide enough current to drive the motor, use transistor to draw current from main input.
