Keyestudio 4WD Bluetooth Multifunction Car Kit

Keyestudio 4WD Bluetooth Multi-functional Car is a learning application development system based on microcontroller and with ATmega-328 at its core.

It has line tracking, obstacle avoidance, IR remote control, Bluetooth remote control and distance detection functions.

This kit contains plenty of interesting programs and can extend an external circuit module to increase more functions of this car.

The kit aims to disengage users from boring theories and obtain capacity of system development when they are learning Arduino.


  • Motor: Voltage: 6-9V Reduction Ratio: 1:48
  • Choosing L298N driver module to control motor separate from the microcontroller
  • Three line tracking modules means higher precision when detecting white and black lines and is able to prevent falling
  • IR remote control module making up a remote control system of the car
  • Using ultrasonic module to realize obstacle avoidance
  • Pairing mobile phone Bluetooth with Bluetooth remote control module to control the car
  • Able to connect with external voltage at 7~12V ,and equipped with various sensors to complete different functions
