* 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

* <span style="color:red;">Procedure to enable ASD function --IMPORTANT</span>
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.
* Open - Automatic shutdown disabled
