This X729 is an ultra-compact advanced uninterruptible power supply expansion board for all current models of the Raspberry Pi using a 40 pin header.
It provides Max. 5.1V 6000mA Power Backup for even the most demanding Raspberry Pi set ups, intelligent and safe power management, safe shutdown, auto power-on, battery reverse polarity protection circuit, AC power loss detection, battery capacity reading, low battery automatic shutdown, real- time clock(RTC), OLED display, Buzzeralarm, PWM Fan and Wide Voltage 6-24V Input.
The X729 reserves the 40-pin header that can be stacked with other Raspberry Pi accessory boards for enhanced applications. The X729 can also be used with the [[X825]] (2.5" HDD/SSD Shield) and [[X857]] / [[X862]] (MSATA/M.2 NGFF SSD shield) for safe data backup.

A: YES. You can connect X708-A1 / X728-A2 battery holder via [BAT: XH2.54 Port to External Battery] of X729 board. But please pay attention to the correct wiring method, if it is reversed, it will burn the X729. <span style="color:red;font-weight:bold">The polarity of the 2pin red and black wire of X708-A1/X728-A2 is opposite to that of X729 BAT XH2.54 port.</span> Q2: Does the X729 support SSD1327 OLED Display or LCD 12864? A:NO, the X729 does not support SSD1327 OLED Display or LCD 12864, only support ssd1306 OLED.
