Compute Module • Re: DS3231 in place of PCF8053

I’ve been inundated by a bout of Covid. I’ve not managed to bridge the ina219 resistors yet. I’ll run some tests after I bridge those

Those two pull-up resistors should be removed not bridged. Bridging them would connect SCL/SDA directly to 3.3V. I don’t think that is the reason why the INA219 isn’t detected though.

Hope you feel better soon.

Hi Trejan,

Thanks so much for your help. It turns out my hierarchical labelling was the issue and the SCL and SDA lines on the INA219 weren't connected to the CM4. have bought a nickel pen and when I connected these lines the INA219 is detected.

Would you still recommend removing the SDA and SCL pull-ups. If so, does this look right (ignore my odd SDA0 and SCL labelling)
