'''[NOTE]''': X728 supports also Raspberry Pi 5 hardware, the installation script is updated. Refer to [[X728-script]]
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 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, battery capacity reading, and a real- time clock(RTC), buzzer alarm.
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 [[X825]]/[[X828]]/[[X829]] (2.5" HDD/SSD Shield) and [[X857]]/[[X862]]/[[X872]] (MSATA/M.2 SSD shield) for safe data backup.

==Update History==
* You can choose to charge when boot up by short "CHG EN" and stop charging at shutdown.
* Added power input connector, which can be used with X715 to achieve 6~60V wide voltage input.
* PCB Size change: 87x63.7mm
'''
* Remove the hardware ASD function and change it to software implementation
* The charging power indicator (LED1-LED4) is relatively brighter than V1.2.
