Short System Overview

UPS PIco HV4.0B/C PPoE is an Ultimate Power Management System HAT that adds a wealth of innovative powerful and development features to the Raspberry Pi® microcomputer! It has been designed especially for the Raspberry Pi® 4, and taking into account all enhanced power and cooling requirement of the Raspberry Pi® 4 models, however in addition it is still compatible with all former Raspberry Pi models. The core functionality of the UPS PIco HV4.0B/C PPoE is to power, protect and automatically shut-down your Raspberry Pi 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 implement on this small HAT. Due to its design, allows to power your Raspberry Pi® directly via PoE Pins and offer low cost solution of Passive PoE of 24V. In addition both powering inputs can be used at the same time GPIO 5V and PPoE. Independent of Passive PoE of 24V cable powering input, there is additional EPR 5.5-28V DC power input capability. One of them (PoE of 24V or EPR 5.5-28V) should be choose.
