ROCK Pi 4 > Hardware > Hardware Revision
There are two models of ROCK Pi 4, 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(ap6256)
- the RJ45 connector on model A doesn't support PoE
- Model A doesn't have the 4Pin PoE header
Change lists
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
