- Soldering the Pogo Pin is necessary if the Raspberry Pi is using soft shutdown.
- The pogo pin is only compatible with Raspberry Pi 4.
- If soft shutdown is done(POWER LED of the RPi remain on in this case), the Raspberry Pi still consumes some energy compared to hard shutdown(where the 5V cuts out). The current consumption in this case is around 250mA for Raspberry Pi 4.
If your project does not have the soft shutdown scenario, you may avoid soldering the pogo pin.
