System Overview

The M.2 – UPS & Power Management HAT is an Ultimate Power Management System HAT designed especially for Raspberry Pi® 5 that open the full functionality of their embedded PCIe M.2(NGFF) interface and adds a wealth of innovative powerful and development features to the Raspberry Pi® 5 microcomputer!

It has been designed especially for the Raspberry Pi® 5 and considers all enhanced power and cooling requirements of the Raspberry Pi® 5 models. It has been designed to work with Official Cooler exploring their enhanced cooling capabilities for Raspberry Pi® 5 as also for the added M.2 devices.

The core functionality of the M.2 – UPS & Power Management HAT is to provide an interface for M.2(NGFF) M-Key (2230, 2242 and 2280) and at the same time protect and automatically shut-down your Raspberry Pi® 5 if there is a cable power failure and can be set to automatically monitor and reboot your Pi once cable power has been restored!

However, it is only a small part of plenty and powerful functionalities that are implemented on this small HAT.  The new M.2 – UPS & Power Management HAT contains two selectable backup power sources that can be used (once at a time). The wide available on the market Battery 18650 Li-Ion or large selection line of XH-2.5 connector (600 mAh – 10 000 mAh) cover any extended Battery Backup request. In addition can be also powered with Super Capacitor of 4000F

The new M.2 – UPS & Power Management HAT is the only one that supplies the Raspberry Pi® 5 RTC with battery backup (J5) and eliminates the need to use an additional battery for this purpose.

Last but not least is that implemented M.2 interface is equipped with 32786 kHz clock, similar to the official Raspberry Pi® 5 M.2 HAT.

The new M.2 – UPS & Power Management HAT does not need any additional powering cable if system is powered via USB-C and thanks to the implemented proprietary monitoring algorithm monitors the and current consumption via GPIO and other powering sources.

The new M.2 – UPS & Power Management HAT offers an External Powering Input of 5V0 – 32V0 supply that can be easily used with any existing Solar Panel. Due to implemented Power Tracking and Dynamic Charging Algorithm, adopt the system power needs to the available Solar Power!

The External Powering Input and the GPIO Powering (via USB-C) can be connected at the same time and system decides what Power Source will be selected!

In addition to the listed powering sources an extra powering source has been implemented – the Passive PoE. Much simpler and much lower cost than the PoE/PoE+. The M.2 – UPS & Power Management HAT can be powered through the Ethernet without expensive equipment, just with a simple power injector that costs 2 EURO. This an ideal solution for a low-cost homemade PoE Systems based on the Raspberry Pi 5 and M.2 – UPS & Power Management HAT
