The present document provides all the information needed to rebuild an RC CAR from scratch using ESP32-based microcontroller units (MCUs), programmed in Arduino environment. The current project applies to the 1:16 Xinlehong (XLH)9136 model, but can be easily adapted to any RC Car model that incorporates:a) DC motor for the forward/backward (FW/BW) movement of the car,b) 3-wireServo Motor (operating at 5V) for the control of the steering wheel,c) 2S LiPo battery (of 7.4 nominal voltage or perhaps of higher voltage if taking into consideration the specifications and limitations of the boards held by the proposed system).
