Overview
  • The SOM-RK3399 is a 260-pin high performance ARM module designed and developed by FriendlyElec. It is based on Rockchip’s 64-bit hexa-core RK3399 SoC. The regular version has 2GB DDR3 RAM, 16GB Flash, onboard 2x2 MIMO dual-antenna WiFi module. Its dimension is 69.6 x 50 mm. It has a TypeC power port and USB-C display port, and can work by itself without a carrier board.
  • The SOM-RK3399 module has various interfaces and ports. It can drive a 4-channel NVMe high speed SSD hard disk by working with a carrier board and the read/write rate can reach up to 1GB/s. It can drive dual-MIPI WDR cameras. It has an eDP interface, MIPI interface, USB 3.0, two USB 2.0 interfaces and other interfaces such as I2C, I2S, SPI, PWM, GPIO, serial and etc.
  • The SOM-RK3399 can run popular OS systems such as Android 8.1, Ubuntu 18.04, Armbian and Buildroot smoothly. It has well established software support. Especially it has NN SDK packages for neural networks in Android 8.1, VPU hardware encoding/decoding in Qt-5.10, and GPU graphic acceleration. It supports development of dynamic GUI with Qt Quick. It is a perfect platform for startups to develop applications and prototypes in facial detection, machine vision, VR, autonomous-driving, deep learning, AI and etc.
