ESP32 Robotics Driver Board

This driver is based on the ESP32-WROOM-32 module and supports wireless communication such as WiFi, Bluetooth and ESP-NOW. It's suitable for different types of robots e.g tracked robots, robotic arms, and many more!

The board features onboard motor control interfaces for 2x DC motors if you're using the encoder, and 4x DC motors without it.

A 40-Pin GPIO extended header is onboard to directly connect the Raspberry Pi and other development boards. You can extend the outer side 40-Pin header for connecting other HATs with cables. 

It features serial bus servos control interfaces, for controlling up to 253 ST3215 serial bus servos with servos feedback. With a multitude of additional peripheral connections (MicroSD card slot, WiFi antenna, external power supply, laser lidar and many more), voltage & current monitoring, onboard 9-axis IMU (QMI8658C + AK09918) and online open-source demos and detailed tutorials for beginners to easily get started, this is a great driver board that is versatile and can be used with lots of different robot projects!
