1. Power Jack and Connectors
Power input | 5Vdc +/- 5% , ≥3A |
DC Power Plug Size | 5.5*2.5mm |
USB power in socket | Type-C |
UPS power output | 5.1Vdc 8A |
Power output connector | XH2.54mm 2pin |
- X708 powers the Raspberry Pi via the 40-pin header (Pin 2 & 4)
- Don't power the Raspberry Pi via the Pi's type-C USB socket
- X708 can be powered via the onboard DC jack or Type-C USB power socket
2. 6-Pin Function Header
Jumper Name | Usage |
---|---|
PLD
(Power loss detection) Pin 1&2 |
|
AON
(Auto power-on) Pin 3&4 |
|
ASD
(Auto shutdown) Pin 5&6 |
1. Battery voltage must be >3Vdc 2. Insert the battery into the holder 3. Wait 3 seconds then insert the jumper 4. If the jumper inserted before battery, remove battery & jumper then repeat step 1, 2 and 3.

4. Power button (Script for power mgnt installed)
Press and Release !! Raspberry Pi and X708 turn on Press and hold for 1~2 seconds Press and hold for 3~7 seconds Press and hold for >8 secondsSystem rebooting |
System shutting down |
Force shutdown |
5. Function LEDs
LED Name | Usage |
---|---|
BAT LOW |
LED red on indicates battery low (≤3.0Vdc) or blue power button pressed (Jumper for ASD inserted) |
5V OUT | LED green on flashing indicates 5V power out and UPS powered by battery |
AC FAIL | LED red on indicates AC power loss or PSU failure or PSU disconnected |
PWR |
LED blue indicates Stays on - Power on Blinks rapidly - system rebooting Blinks slowly - Shutting down |
