Quick Overview
The DIYables 2WD Smart Robot Car Chassis Kit bundles a fully pre-assembled 2WD acrylic chassis with an L9110S Dual DC Motor Driver Module, giving you everything needed to build a programmable robot car. The chassis comes with two DC motors equipped with speed encoders, a battery holder, and pre-drilled acrylic plates — all assembled and ready to connect. No soldering is required as motor wires come pre-soldered and all mounting holes are standard size.
The included L9110S motor driver supports 2 DC motors or 1 four-wire two-phase stepper motor with a supply voltage of 2.5V to 12V and 0.8A maximum current per channel. Its compact 2.8 x 2.1cm PCB features 3mm mounting holes for easy installation on the chassis. The encoder feedback from both motors enables precise closed-loop speed and position control for accurate line following, obstacle avoidance, and autonomous navigation.
Ideal for STEM education, robotics learning, Arduino and ESP32 programming practice, line follower builds, RC car projects, and any beginner-to-intermediate robotics application using Arduino, ESP32, ESP8266, or Raspberry Pi.
