RPi Power HAT with built-in DVM, current & temperature measurement, CPU statistics, + much more.

Unique power HAT provides stable and accurate power while measuring voltage, current, ambient temperature, CPU temp, clock speed, and core voltage. The monitored parametric data is displayed on a small OLED display. Integrated active cooling varies fan speed using ambient or RPi CPU temperature. Saf...

Re: RaspberryPi 4: heatsink or fan

Here's what the Raspberry folks have to say on the subject of cooling: The Pi4B will operate perfectly well without any extra cooling and is designed for sprint performance - expecting a light use case on average and ramping up the CPU speed when needed (e.g. when loading a webpage). If a user wishe...

Hi, 1st post here. I want to implement some form of safe power removal on the RPi 4 and I thought I could make use of the GPIO POWEROFF overlay feature. I have read that this works on the RPi 3/3B but does not work on my RPi 4. My environment: RPi 4, 2GB ram. Installed latest <recovery> bootloader r...
