X728 Expansion Board UPS Power Management Board Automatic Startup Safe Shutdown for Raspberry Pi

X728 Expansion Board UPS Power Management Board Automatic Startup Safe Shutdown for Raspberry Pi

Description:
-X728 is an advanced uninterruptible UPS power management expansion board, suitable for all Raspberry Pi with 40-pin connector.
-It provides 5.1V up to 8000mA power backup, smart and safe power management, automatic power-on, safe shutdown, power failure detection, power path management, RTC function.
-X728 retains the 40-pin connector, which can be stacked with other expansion boards of Raspberry Pi to enhance applications. X728 can also be used with X825/X828/X829 (2.5" HDD/SSD expansion board) and X857/X872 (MSATA/M.2 SSD expansion board) to ealize safe data backup.

Application: for Raspberry Pi 1 Model B+/2 Model B/3 Model B/3 Model B+/3 Model A+/4 Model B

Power Output:
Power supply through Type-C socket: 5Vdc±5%, ≥3A, through DC power jack: 5Vdc±5%, ≥4A
UPS output: 5.1V±5% max 8A
UPS charging current: 2.3-3.2A
Terminal battery voltage: 4.24V
Recharge threshold: 4.1V

Note:
-18650 batteries (not included) do not need to be equipped with a protective plate, otherwise the charging will be slower.
-Do not supply power through the Micro USB or Type-C port of the Raspberry Pi.
-Do not use 18650 batteries with built-in protection coils.

Function of Jumper Cap:

①ASD=Automatic shutdown
Short circuit-automatic shutdown when battery power is low (≦3V DC) (before enabling this function, the battery must be >3V and installed)
Open-short circuit-disable automatic shutdown
②Short circuit-automatically shut down after power on (there will be a delay of 3 seconds before turning on)
Turn on-disable automatic shutdown
③Short circuit-enable power failure detection (if the power adapter is not connected, it is active)
Turn on-disable power failure detection

Operating System:
-Raspbian Stretch
-Safe shutdown function test is Raspbian, other operating systems need to be tested

Uninterruptible Power Supply (UPS):
-Can work continuously for up to 10-30 hours (depending on battery type and number of use)
Maximum 5.1V 8000mA power backup, even the most demanding RPi settings.
-Can be stacked with X728-A2 (the battery base can hold two batteries) to increase battery capacity.
-Support 3000mA fast charging.
-Integrated overcurrent protection and overvoltage protection.
-Integrate Maxim's fuel gauge system (read battery voltage and percentage through i2c).
-Integrated 10A fully integrated synchronous boost converter.
-Intelligent automatic charging and discharging.
-Onboard 4 green LEDs to display battery charge and discharge levels of 25%, 50%, 75% and 100% respectively.

Smart and Safe Power Management:
-Equipped with a reset switch button for convenient power control.
-Press the button to turn on.
-Press the button and hold for 1-2 seconds to restart.
-Press the button and hold for 3-7 seconds to achieve a safe shutdown.
-Press the button and hold it for >8 seconds to force shutdown.
-Support safe shutdown and complete shutdown through software.
-The onboard blue LED displays the boot, restart and shutdown status.
-AC power loss or power adapter failure detection (LED and GPIO detection).
-The on-board pin header allows the power supply to be selected when automatic power is selected. The on-board pin header connector can select automatic power on when power is supplied.
-Automatic safety shutdown when the battery is low (voltage <3.0V).
-Ultra-low standby power consumption to maximize battery life.
-Can run in charging mode and boost mode to achieve comprehensive system management and battery power management.
-Integrated "system access" path, which transmits the input voltage to the system Integrated -IN-to-SYS through path, which can transmit the input voltage to the system.
-Advanced system power path management to avoid frequent battery charging and discharging.
-Advanced system power path management, allowing 3A fast charging and powering the Raspberry Pi at the same time.

Integrated hardware DS1307 real-time clock (RTC) and battery backup:
-When the Raspberry Pi is turned off, it will record the time
-After turning on again, the Raspberry Pi will synchronize the current date and time
-Use 18650 battery to maintain date and time-no additional battery required
-Power Raspberry Pi via 40-pin connector-no additional cables required
-Onboard DC power jack (5.5*2.5mm), Type-C socket, convenient for power input
-The PH2.0 connector on the board allows to connect an external power switch, DIY your perfect shell
-The onboard XH2.54 power output connector allows to supply power to other devices
-Keep 40 pins, can be stacked with other Raspberry Pi expansion boards

Package List:
-1 x X728 Expansion Board
-1 x Screw Pack

Note:
-Before charging the battery (not included), you must read the safety instructions and warnings.
-Lithium polymer and lithium ion batteries are volatile. Failure to read and follow the instructions below may result in fire, personal injury and property damage.
-Do not connect the wrong polarity when charging and discharging. Always check the polarity of the battery connector to ensure that "+" to "+" and "-" to "-".
-Do not mix old batteries with new batteries and batteries of different brands.
-Lithium batteries have a cycle life. When the old batteries have reached the end of their service life or have been used for more than two years, please replace them with new ones, whichever comes first.
-Please put the battery in a fireproof container when charging. Please do not leave X728 on wooden materials or carpets.
