1.3 DC/DC Converter and e-Latching Power Switch
Witty Pi 4 comes with a DC/DC converter on board, which allows you to power your device with
6~30V power supply. You can also power your device with 5V via the USB type C connector.
Witty Pi 4 also implements an e-Latching power switch, which is very similar to the power switch on
your PC/Laptop computer. You can gracefully turn on/off your Raspberry Pi with a single tap on the
button. The software running in background will execute the shutdown command before the power
gets cut, and it avoids the data corruption caused by “hard” shutdown.
