  Products Paramenters: Microprocessor CH340G ATMEGA328 Power supply 2 removable 3.7v lithium batteries Input  Infrared sensor (four-channel infrared sensor module) Motor  DC geared motor Motor drive  L9110S module Input  Ultrasonic module (HC-SR04) Product Features： 1. The main control board: CH340 development board.  2. The motor drive module uses a typical L298N module to drive a DC motor. 3. The infrared signal detection module uses four infrared light pairs to detect the black line and realize the tracking function. 4. The ultrasonic sensor module: HC-SR04 module, through which the distance is measured, so as to realize the ultrasonic obstacle avoidance function.
