|
||
## 描述
|
||
|
||
**COMMU** 是M5Stack堆叠模块系列中的一款，通信转换模块.其内部集成了2个**I2C**接口、1个**TTL**接口、1个**CAN**接口、1个**RS485**接口.能够满足开发时遇到的各种通信转换需求.
|
||
|
||
默认连接:TTL - UART0，RS485 - UART2.ESP32允许引脚映射重分配，所以你可以将TTL或是RS485接口重新定义到其他引脚.
|
||
|
||
## 产品特性
|
||
|
||
- 支持I2C,TTL,RS485,CAN等多种通讯协议
|
||
|
||
## 包含
|
||
|
||
- 1x M5Stack COMMU 通信转换模块
