Seeeduino Xiao + nRF24L01+2.4G + MPU6050

Hello
I’d like to connect Seeeduino Xiao with nRF24L01+2.4G and MPU6050
to send x, y, z sensor values via nRF24L01 communication
I was doing it successfully with the code below, when I was testing with Arduino Nano boards
But I don’t have any idea where should I plug the pins with Seeeduino Xiao

Is there anyone who can explain the Pinouts?

Is it a connection problem? Can you provide a photo? I can check it for you.

Thanks for your reply
Actually I was running Seeeduino xiao board and Arduino Nano Board
But I tried to run 2 Seeeduino Xiao board
And fortunately everything works fine
:slight_smile:
