The LK COKOINO 4WD Robot Control Board is very powerful, it not only has the function of Arduino UNO R3, but also expands the interface for infrared receiver, ESP - 8266 module, DRV8833 motor driver, etc.
It can be used as a UNO board for some sensor module experiments, and also as a control board to drive a 4-wheel car. Alternatively, you can DIY more interesting projects with ESP - 8266 on the 4WD Control Board
Use DC to DC 5V power supply regulator system, make it not easy to heat up and save more power, and it can reach a maximum output 5A current.
Use more powerful DC3.3V voltage regulator chip, its maximum load up to 3.3VŀmA
Add A6 analog input port, it can be connected to analog signal module. Add two DRV8833 motor driver chips, it can drive four motors
