    Function Description        X710            
Power Jack, power input and power output
4-Pin Function Header
  Power input range  6~36Vdc , ≥ 2A
  DC Power Plug Size  5.5*2.5mm
Power input / output connector  XH2.54mm 2pin


1. X710 powers the Raspberry Pi via the 40-pin header (Pin 2 & 4)
2. Don't power the Raspberry Pi via the Micro USB or Type-C socket
3. XH2.54 power input connector connects to DC power jack directly.

4. Don't connect any 5V-powered device to XH2.54 power input

5. X710 can be powered via the onboard DC jack or XH2.54 power

   input connector.

Pin Number Usage
Pin 1 and Pin 3
 Short - Auto power-on when power applied
 Open - Power on when power button pressed 
Pin 2 and Pin 4
