  Brief introduction  

MAKER-ESP32-PRO is a signature product for maker education developed based on

Espressif Systems' ESP32-WROOM-32 module, featuring 4MB Flash and a single-chip

solution integrating 2.4 GHz Wi-Fi + Bluetooth dual-mode.

Onboard, it supports 4-channel encoder motors and DC motors with a maximum driving

current of 3A. The encoder/DC motors share the same driver pins the same port cannot

drive encoder and DC motors simultaneously.
