Pico Plus 2w - QW/ST issue

Support
1

I’ve just received a brand new Pico Plus 2w, which I’d planned to connect to a number of I2C sensors (Adafruit boards) using QW/ST and then use python (either micro or circuit) to upload the data to an Influx database on my network.

The issue I’m having is, whatever I do, I can’t seem to get any life out of the QS/ST interface.
I’ve tried both Micropython and Circuit python, but however I try to connect to my sensors (I’ve tried multiple, and multiple QW/ST cables) or scan the I2C bus, I get nothing.

The same sensors on a Raspberry Pico 2w, with a QW/ST cable connected to a breadboard, work perfectly.

Am I don’t something wrong or do I have a faulty Pico Plus 2w? Or is this a firmware issue?

Thanks!
Richard

What GPIO Pins are you using in your code?
It uses GP4 for SDA and GP5 for SCL.
This is the code I’m using on mine.

import pimoroni_bus
from pimoroni_i2c import PimoroniI2C
i2cbus = PimoroniI2C(4, 5)
