ESP32 Driver Board for Robots, WIFI, Bluetooth and ESP-NOW

The robot-specific multifunctional driver board offers greater possibilities for robots, designed to work with the ESP32-WROOM-32 module and can be programmed using Arduino IDE. It supports various wireless communication methods such as WIFI, Bluetooth, and ESP-NOW.

The driver board features commonly used robot component interfaces including DC motor interfaces with and without encoders, bus servo interfaces, IIC interfaces, Lidar interfaces, PWM servo interfaces, and an SD card slot.

Additionally, the driver board offers a range of on-board resources for convenient robot project construction, such as a 9-axis IMU, temperature sensor, automatic download circuit, Lidar serial port to USB circuit, and bus servo control circuit.

• 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.

General Driver For Robots

Rich Peripheral Interfaces
Suitable For Different Types Of Robots

ESP32 Main Controller
Rich Resources For Secondary Development

Built-In WiFi And Bluetooth, As Well As ESP-NOW Support, For Wireless Communication

Support Multiple Peripheral Connections

40PIN GPIO Extended Header

The inner side 40PIN header is for directly connecting to the Raspberry Pi or other host boards. And extend the outer side 40PIN header for connecting with other HATs via cables

Serial Bus Servo Control

Allows Controlling Up To 253 ST3215 Serial Bus Servos At The Same Time

Note: One channel UART can control up to 253 bus servos, but due to the high power of the servos, it is necessary to consider whether the power supply solution is enough when using too many servos.
