Hi to all, [PXL_20240209_182709045] As you can see from the picture, the TX and RX pins of this Arduino R4 Minima are on. Another strange thing is the ADC always shows 0 from every channel. Do you know why? I uploaded the Blink example and the built-in led works normally.

Strange behaviour of R4 Minima

Did the RX and TX LEDs remain on while the board was running the "Blink" sketch?
