51 microcontroller Bluetooth car

Overview

This board, measuring 9.74*9.42cm, controls a small car via Bluetooth using a 51 microcontroller. Free prototyping is available from JLCPCB. All components are plug-in, making it easy to use and suitable for beginners. The core board uses an STC89C52RC controller; the motor control module uses two mini L298N modules for external connection; the Bluetooth module is external for controlling the car; and the buzzer module is external for sound output.
