RP2040-Zero (WS-20187)

Hi,

The pinout diagram for the RP2040-Zero MCU board on your web site shows I2C1 SCL on pin 14 and SDA on pin 15. When wired like that I’ve been getting all zeros from the I2C sensor I’m using. I double checked the Waveshare web site and their pinout diagram for the same board has the 2 pins swapped ie SCL is on pin15 and SDA is on pin 14. When I swap the wires it works correctly.

So your pinout diagram needs to be corrected.

best regards

Peter

Hi @Peter46549 ,

Thanks for bringing this to our attention. I can imagine that was a frustrating problem to solve.

I have passed this information on to our team, who should have the product page updated shortly.
