    ROCK Pi X >  Hardware >  Hardware Revision

There are two models of ROCK Pi X, model A and model B. Model A is a stripped down version of model B. The differences are:

  • Model A doesn't have wifi/bt model(ap6255)
  • the RJ45 connector on model A doesn't support PoE
  • Model A doesn't have the 4Pin PoE header

Change lists


  • This is the first public batch, full working with all functions
  • eMMC socket on the PCB with eMMC module support
  • Use external WiFi antenna with additional u.FL stick antenna by default


  • Wifi antenna circuit layout is tunned to improve signal strength/sensitivity
  • eMMC is now soldered on board!
  • Add label/silkscreen for all connector/ports
  • Slightly adjust the USB/RJ45 connector position to support SATA HAT. Note: USB/RJ45 connector position is not compatible with v1.3 or earlier.
