Rockpi4

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.

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.
