4.Introduction to expansion board

Expansion Board Introduction

1. Expansion Board Introduction

The Dofbot-SE expansion board is compatible with multiple main controllers, but only one main controller can be connected to the expansion board at a time. It supports Raspberry Pi, Jetson Nano, STM32, and also has a reserved external I2C interface that can support other main controller boards with I2C functionality.

2. Component Locations and Functions on the Expansion Board

Special Note: The 22.04 version VM comes with a large model voice interaction module, replacing the voice recognition and voice broadcast module on I2C interface #9. If you purchased the module previously and want to experience ROS2 related cases, the voice-related cases are not universally applicable.
