• [FAQ]

  1/ What do you need to use Raspberry Pi X400 V3.0 Audio Expansion Board?

  (1) A Raspberry Pi board

  (2) Power supply: 6-26V DC，2A-3A recommended(We have 24V 2A power supply recommand)

  (3) A X400 V3.0 use matching case (optional)

  
  

  
  

  2/ Why the power switch is not work normally? 

  
  There is a jumper cap on the PWR (on the X400 board beside the 3.5mm jack headphone), when using an external power switch to control power on/off, please remove the jumper cap. Please refer to the picture
