Produktbeskrivelse
This is the 1.5 release of Raspberry Pi 4 power management board called XPI – ready to use.
This board supply safe power off and power on via software or via an external push-button. Easy to install. Just power in and power out to the Pi and a 2-wire cable to the Pi’s GPIO pins are required to operate this board.
Well written guidelines and help are also available here on minibase.no. Raspberry Pi 4 power management board is fully assembled.
All components are soldered and it’s delivered with the latest firmware on the Microcontroller (MCU). This product is supplied with 2 x high current MOSFET switch transistors with no external cooling required.
How it works
With this power management board, you can push an external button to start the Raspberry Pi 4 or if the Raspberry Pi 4 is already running, the Raspberry Pi 4 will begin the shutdown process and after the shutdown is completed the power management board will turn off all power to the Raspberry Pi 4. Or you select shutdown in the Raspberry Pi OS, the signal will be sent to the power management board and the power management board will wait for the Raspberry Pi 4 ended all it’s activity and then turn off power to the Raspberry Pi 4. Safe and secure.
