Hey!

Anyone who has tried using multiple qwiic rfid readers to only one microcontroller over one i2c?

Haven’t tried it and I don’t think we have code for using more than one, but as long as each board has a unique address (there are two addresses available) you can connect two up to the same I2C bus.

Anymore than two and you would need a [[Qwiic MUX](https://www.sparkfun.com/products/16784).]([SparkFun Qwiic Mux Breakout - 8 Channel (TCA9548A) - BOB-16784 - SparkFun Electronics](https://www.sparkfun.com/products/16784))
