*The SOM-RK3399v2 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 4GB LPDDR4 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-RK3399v2 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-RK3399v2 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.

==More OS Support==
===DietPi_NanoPCT4-ARMv8-Stretch===
DietPi is a light-weighted system. Its image file can be as small as 345M bytes. It takes much less resources. It has a DietPi-RAMlog utility. These features allow users to exploit its huge potentials.<br />
FriendlyElec doesn't provide technical support for DietPi.<br/>

Here are some steps to boot a DietPi:<br />
* Download DriverAssitant_v4.5.tgz, extract it and install it on a Windows PC;
* Download DietPi_NanoPCT4-ARMv8-Stretch [https://dietpi.com/downloads/images/DietPi_NanoPCT4-ARMv8-Stretch.7z DietPi_NanoPCT4-ARMv8-Stretch], extract it, enter "Image_and_Tools" and run "AndroidTool.exe" as administrator 
* It is assumed that the section configuration(parameter.txt) is imported and here is a table:
[[File:AndroidTools_DI_02.png|Download DietPi_NanoPCT4 Image|800px|]]
* Connect a 12V/2A DC power cord and an HDMI monitor to your T4, connect your T4 to a PC with a Type-C cable. Press and hold the Recovery button and the Power button for at least 1.5 seconds AndroidTools will prompt that a LOADER device is found
<br/>a)If eMMC hasn't been flashed with an image or the image inside is removed or damaged this eMMC will be recognized as a MASKROM device; 
<br/>b)You can hold both the BOOT button and the Power button for at least 5 seconds to force the board to enter the MASKROM mode; 
<br/>c)If your system shows "no device is found" you need to check if you have installed a driver or if your Type-C cable works and then try it again; 
<br/>d)If your system is booted successfully you can run "reboot loader" on your board via adb or SSH and force your board to enter the LOADER mode.<br/> 
* Click on "Run" to download your wanted image to eMMC. A while later after the image is flashed successfully your board will be rebooted automatically.<br/>
