Overview

The X725 is an improved version based on the X720. We absorbed feedback from buyers and added the AUTO PWR ON/AUTO UPS function etc, remove the RTC function.

The X725 is suitable for all current models of the Raspberry Pi using a 40 pin header. Firstly, X725 is the UPS expansion board using 18650 lithium battery, supports power output up to 5.1V Max. 8A, and it also provides intelligent and safe power management, remote power on/wake on lan(WOL), safe shutdown and full poweroff through software, , and second 10/100M fast Ethernet. The X725 reserves the 40-pin header that can be stacked with other Raspberry Pi accessory boards for enhanced applications. The X725 can also be used with the X820, X825, X850, X855, X856, X828 (HDD/SSD Shield) for safe data backup.

Features

  • FOR USE WITH: Raspberry Pi 1 Model B+/ 2 Model B / 3 Model B / 3 Model B+ / 3 Model A+ / 4 Model B
  • OPERATING SYSTEM: Raspbian Stretch (Safe shutdown function tested for Raspbian, other operating systems to be tested and advised)

Key features

  • Smart Uninterruptible Power Supply (UPS), upto 5.1V Max. 8000mA Power Backup
  • Can work with single or dual 18650 Lithium Ion battery
  • Provides continuous operations for up to 10hours (depending on battery type used)
  • Supports 2A via micro-USB socket or 3A via DC jack fast charging
  • With battery protection circuit over current protection and over voltage protection
  • Integrated Maxim's fuel-gauge systems (Reading battery voltage and percentage via i2c)
  • With 10-A fully-integrated synchronous boost converter
  • Intelligent automatic charging and discharging
  • Automatic safe shutdown when battery low (voltage <3.0V)
  • On-board LED blinking when the battery condition low (voltage <3.0V)
  • On-board LEDs show the status of battery charging and discharging
  • On-board pin header to select auto power-on when power supplied or battery installed
  • With second 10/100M fast Ethernet, supports remote power on/wake on lan via Link-change, Magic packet, MS wakeup frame, on-board LED shows the status of power on/wakeup packet indication

Technical Specification

  • Terminal Battery Voltage : 4.2V
  • Recharge Threshold : 4.1V

On-board button operation

  • Intelligent and safe power management
  • Press the power button to turn on
  • Press the button and hold for 1~2seconds to reboot
  • Press the button and hold for 3~7seconds to implement safe shutdown
  • Press the button and hold for >8seconds to force shutdown
  • Supports safe shutdown and full poweroff through software
  • On-board LED shows the status of power on, reboot and shutdown

Note:

  • The on-board button switch is mometanary button switch.
  • The operation of using the external mometanary power switch from Geekworm is exactly the same as the operation of the on-board button switch.

Power Supply & OUT

  • On-board DC jack (5.5*2.5mm) and micro-USB socket convenient for power input.
  • Power supply via Micro-USB socket : 4.7~5.5Vdc, 2.5A, Via DC power jack : 4.7~5.5Vdc ±5%, ≥3A
  • UPS output : 5.1V ±5% Max 8A
  • UPS charging current: 2A via Micro-USB socket, 3A via DC jack
  • Powers the Raspberry Pi via the 40-pin header
  • Power management and second Ethernet can still work without battery (The premise is that you are using an external power supply to the X725 via DC socket or Micro USB socket)
  • On-board 2.54 port connector allowing to connect external power switch and DIY your perfect case

WARNING:

DO NOT APPLY POWER TO YOUR RASPBERRY PI VIA THE PI's MICRO USB or Type-C SOCKET.

DO NOT APPLY POWER TO X725 VIA THE MICRO USB SOCKET AND DC JACK AT THE SAME TIME.

DO NOT USE 18650 BATTERY WITH BUILT-IN PROTECTION CIRCUIT

Packing List

  • 1 * X725 Expansion Board
  • 8 * Screw M2.5 *6mm
  • 4 * Spacer F/F M2.5 *23mm
  • 4 * Spacer F/M M2.5 *23mm
  • 3 * Jumper link Pitch 2.54mm
  • 1 * USB to Micro USB 2.0 cable (for WOL)
