X725

Description

The X725 is a multifunctional expansion board for all current models of the Raspberry Pi using a 40 pin header.
It provides intelligent and safe power management, remote power on/wake on lan, safe shutdown and full poweroff through software, an advanced uninterruptible power supply, 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.

Note & Warnings

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.

Compatibility

  • Raspberry Pi 1 Model B+ /2 Model B/3 Model B/3 Model B+/3 Model A+/4 Model B
  • OS: Raspbian Stretch
NOTE: Safe shutdown function tested for Raspbian, other operating systems to be tested and advised
