Raspberry Pi 4B/3B+/3B X708 V2.0 UPS HAT & Power Management Board with Cooling Fan

Update:

• Added protection circuit and alarm function when the battery is reversely connected (RESERVED will be on)
• Supports the control of two fan speeds
• Solved the problem that the old version can't charge when the battery is exhausted
• Improved AUTO ON function
• Added battery over-discharge function
• Improved power path management function: when external AC power is supplied, the AC PSU supplies power to the UPS shild and also charges the battery.

Note: The X708 is compatible with the X857-C3/X857-C1/X829-C1/X825-C7 Case, but X708 do not support the X825-C1 to X825-C6 case.

Overview
The X708 is an advanced uninterruptible power supply expansion board for all current models of the Raspberry Pi using a 40 pin header. It provides 5.1V Max. 6000mA Power Backup for even the most demanding Raspberry Pi set ups, intelligent and safe power management, safe shutdown, AC power loss/ power adapter failure detection , auto power-on, full poweroff from software, and a cooling fan.

The X708 reserves the 40-pin header that can be stacked with other Raspberry Pi accessory boards for enhanced applications. The X708 can also be used with the X825/X828/X829 (2.5" HDD/SSD Shield) and X857/X862/X872/X873(MSATA/M.2 SSD shield) for safe data backup.
