[Overview]
The X728 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 8000mA Power Backupfor even the most demanding Raspberry Pi set ups, intelligent and safe power management, safe shutdown, auto power-on, full poweroff from software, battery reverse polarity protection circuit, and a real- time clock.
The X728 reserves the 40-pin header that can be stacked with other Raspberry Pi accessory boards for enhanced applications. The X728 can also be used with the (2.5" HDD/SSD Shield) and / (MSATA/M.2 NGFF SSD shield) for safe data backup.
[Updateion History]
X728 V2.2, upated on July 7th, 2022:
