Introduction

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.

Getting started

Refer the ROCK Pi 4 getting started page for how to start with ROCK Pi.

Refer Installation for how to install images on ROCK Pi.

Hardware

Sweet tips about ROCK Pi 4 Board

  • 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 3.3V supply through a 4.7K pull-up resistor.
  • Pin 19, 21, 23, 24 are laid out directly to the pins of SPI device on board.
  • Pin7 is laid out directly to the pin of MIPI CSI on board.
