    ROCK Pi 4 >  Hardware >  Hardware Revision

There are three models of ROCK Pi 4, model A, model B and model C. Model A is a stripped down version of model B. Model C is an enhanced version of model B. The differences are:

  • Model A vs. Model B
    • Model A doesn't have wifi/bt model(ap6256)
    • the RJ45 connector on model A doesn't support PoE
    • Model A doesn't have the 4Pin PoE header
  • Model B vs. Model C
    • Model C adds one additional mini DP port based on model B
    • Model C changes the HDMI connector from type A to type D(micro HDMI)

Change lists

Model A | B

V1.3

This is the first MP version, the key features are:

  • User type C for power, adds QC&PD trigger IC
  • LPDDR4 for 1/2/4GB ram
  • Use odroid compatible eMMC socket as storage
  • On board wifi antenna

V1.4

V1.4 is a slightly updates based on the V1.3, solves the issues reported by users. The schematic is the same as V1.3.

  • Changes the USB3 OTG label to simple L/H for Host/Device
  • Add external wifi antenna option, not soldered by default
  • Change the headphone footprint to through hole leg one
  • Change user status LED from red to blue(blinking red led is confusing for some user)
  • A 4MB(32Mbit) SPI flash is pasted by default, for future SPI booting support

V1.6(4B+)

  • Add USB C input voltage measure from SoC ADC
  • Add EEPROM (BL24C16A) for mac address and serial no.
  • eMMC socket changed to on board chips
  • Three buttons are soldered by default.(1: Maskrom 2: Reset 3: Recovery) See [picture here].

Model C

v1.2

  • change to a more tight micro HDMI connector
