Introduction

The multifunctional driver board specially designed for robots provides more possibilities for robots. Based on the ESP32-WROOM-32 module, Arduino IDE can be used for development, and it supports a variety of wireless communication methods, including WIFI, Bluetooth, and ESP-NOW.

Onboard versatile commonly used robot component interfaces, including DC motor interface with encoder, DC motor interface without encoder, bus servo interface, IIC interface, Lidar interface, PWM servo interface, SD card slot, etc.

A variety of resources are on board, which is convenient for robot project construction, including a 9-axis IMU, temperature sensor, automatic download circuit, Lidar serial port to USB circuit, bus servo control circuit, etc.

Features

• Based on the ESP32-WROOM-32 module, supports wireless communication methods such as WIFI, Bluetooth, and ESP-NOW.
• Onboard motor control interface for 2x DC motors with encoder or 4x DC motors (two groups) without encoder.
• Onboard serial bus servos control interface for controlling up to 253 ST3215 serial bus servos and obtaining servo feedback.
• Onboard 9-axis IMU can obtain attitude and heading information at any time.
• 7~13V voltage input can be powered directly by 2S or 3S lithium battery.
• Automatic download circuit for easy uploading demos.
• Support input voltage and current monitoring.
• Onboard TF card slot.
• Onboard Lidar interface and integrated UART to USB function.
• IIC interface for expanding other peripherals such as OLED, IMU, and other IIC communication protocols.
• Multi-functional extended interface, adapting to remaining interfaces for additional functions, such as controlling servos or relays.
• 40PIN extended header for connecting to Raspberry Pi, Jetson Nano, and other host computers, communicating via serial port or IIC, and powering the host computer.
• Provides open-source demos for onboard resources, and detailed tutorials for beginners to get started.
