ROCK Pi 4 is a Rockchip RK3399 based SBC(Single Board Computer) by Radxa. It can run android or some Linux distributions. ROCK Pi 4 features a six core ARM processor, 64bit dual channel 3200Mb/s LPDDR4, up to 4K@60 HDMI, MIPI DSI, MIPI CSI, 3.5mm jack with mic, 802.11 ac WIFI, Bluetooth 5.0, USB Port, GbE LAN, 40-pin color expansion header, RTC. Also, ROCK Pi 4 supports USB PD and QC powering.
ROCK Pi 4 comes in two models, Model A and Model B, each model has 1GB, 2GB or 4GB ram options. for detailed difference of Model A and Model B, please check Specifications.
ROCK Pi 4 comes in three models, Model A and Model B has 1GB, 2GB or 4GB ram options, Model C has 4GB ram only. For detailed difference of three models, please check Specifications.

- UART2 is enabled as U-boot and Linux serial console by default. Check Rockpi4/dev/serial-console to use. Check Rockpi4/hardware/devtree_overlays to disable serial console on UART2.
- UART2 & UART4 support a wide range of baud rate. It includes but not is not limited to the following baud rates. For instance, 115200bps. 500000bps, 1500000bps and so on.

- Function marked with color orange is the default function of this pin.
- Except Pins for power supply, all pins are laid out directly to Soc RK3399.
- For pin 3, 5, 27, 28, 29 and 31, each pin is connected to the 3.0V supply through a 4.7K pull-up resistor.
