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?
