Hi,
I have a Enviro HaT mini from Pimorini. I wanted to use only sensor like BME280 and LTR559 for my project with Pico Hat mini connections so that I can plug in Automation Hat with main header.
When I connect enviro hat with the main header then light-procimity sensor works fine but if I want to use only 4-wire I2C connection then I get the error while accessing LTR sensor. The BME works though.
"OSError error 121 remote I/O error".
Are there some more pins the sensor could be using? The following link shows that the Hat uses 16 pins in total. I had tried connecting all 16 of them with wire but still the LTR sensor did not work. Does someone has an idea?
