[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:
- Adds Battery Reverse Polarity Protection circuit & LED indiciators on v2.2
X728 V2.1, upated on Sept., 27th, 2021:
- New add a buzzer controled by CPIO20
- DC jack is changed from DC5525 to DC5521
X728 V2.0, updated on Aug., 2nd, 2021:
- Improve the power path function, the battery will only charge and not discharge when connected to the PSU.
- You can choose to charge when boot up by short "CHG EN" and stop charging at shutdown.
- Use ultra-low voltage MCU.
- Increase battery overcharge, overdischarge protection circuit, added power input surge protection circuit.
- Added power input connector, which can be used with X715 to achieve 6~60V wide voltage input.
- V2.0 PCB Size update to 87x63.5mm, the V1.3 PCB size is 85x63.5mm.
- The battery holder "+" and"-" mark direction has changed compare with X728 V1.3. Please pay attention and follow the directions to insert the batteries.
X728 V1.3, updated on February, 2021:
- V1.3 removes the ASD harware function and adds power surge protection function, but we new add the software shutdown python script when battery is low voltage, please rerfer to X728-Software
- The charging power indicator (LED1-LED4) is relatively brighter than V1.2.
