M5Stack同时可连接多少IO设备

请问M5Stack同时可以连接多少外部设备？比如我想控制4个麦克纳姆轮和多个舵机，并且同时连接巡线传感器、超声传感器、颜色识别传感器等。

Use the unit sensors with have a i2C connection. As long as they have different addresses you can hook up up to 127 different sensors/ actuators on the same bus. With the PaHub you can hook up 6 units having the same I2C address. For analog sensors you can use the PbHub ... So sticking to the I2C bus the limit of devices you can use is probably the power source you are using ......
