Product Description

Introduction

1.jpg

WRTnode, which is based on Wi-Fi AP-Soc, is an open source development board hardware. There is a mediatek MT7620n chip in it.

It is mini, cheap and has pretty low power consumption and reasonable capability of computing. Besides, It is born to high speed of Wi-Fi network exchange.

What does WRTnode aim for? Maybe different people have different opinions. Our team considers it as a high speed and digital version of "Arduino". Since it could connect and interact with USB devices like camera and sound card, we can collect images and voices at the same time and stream out multimedia stream in real time. After a layer of A / D converter, It could directly interact with physical world like all kinds of sensors and motors.

OpenWrt, which is a distribution of embedded Linux, is the system of WRTnode. When multimedia information and various of input and output control focus on a Linux system which has small volume, low power consumption and enough computing capacity, after porting and optimizing the existing pattern recognition, artificial intelligence and other applications, we may setup a series of interesting "smart" devices. And they are supplemented by powerful network capabilities. we may get a structure of MATRIX and NODE. This is where the node in WRTnode comes from.

We pronounce WRTnode as what-node.

As an OpenWrt supported device, WRTnode applies everything on wiki.openwrt.org. We highly recommended take wiki.OpenWrt.org as the trusted reference.

Starting guide

What you will get?

5.jpg

You get the WRTnode in a very nice transparent plastic box, inside the box you get WRTnode stickers too. The box is useful to store various small items useful for WRTnode (USB memory stick, I2C port expander module, jumpers and so on).

The micro USB standard plug will be connected to the WRTnode board and to power the board itself. The USB standard type A plug will be connected to any USB wall adapter, any PC USB port, any USB 5Vdc power supply (at least 500mA (0,5A) current). The USB standard type A receptacle can connect any USB device to the WRTnode board, for example can connect a USB memory stick:
