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.
- You must read these safety instructions and warnings before charging your batteries.
* Lithium Polymer and Li-ion batteries are volatile. Failure to read and follow the below instructions may result in fire, personal injury and damage to property if charged or used improperly. * Never make wrong polarity connection when charging and discharging battery packs. Always double check polarity of battery's connector to make sure "+" to "+" and "-" to "-". * Do not mix and use old batteries and new batteries, or batteries with different brand names. * Lithium batteries has it's cycle life, please replace old battery with new one when it reaches it's service life or when it is two year old, whichever comes first. * When charging Battery Pack, please put battery in a fire proof container. Please don't leave the X720 on the wood material or carpet and unattended. * Must keep the X720 away from children.
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
