So, I'll explain my problem, which I've been struggling with for a while (about 3 weeks). I have a Raspberry Pi 4 B connected to a Pironman board (inside the case https://www.sunfounder.com/products/ras ... 587c&_ss=r ).
I'd like to connect the other component, Waveshare Power Management HAT (B), to automatically start the Raspberry Pi. I've already managed to install it on the Raspberry Pi, and it was visible on the I2C, but I can't seem to update the system time. Digging around on the component's page https://www.waveshare.com/wiki/Power_Management_HAT_(B), and trying with the AI, I realized I might be missing some connections. I can get by with the software, but the connections are my nemesis.
Thanks to anyone who will have the patience to reply.
