Product Description

This is a TL-WR703N Clone. It is pre-flashed with OPENWRT, which has USB camera support. Morevoer, the TTL UART is connected to headers, so it can be interfaced to Arduino to control robot.


Explaination of the interfaces:


1. The functions of different ports and how to wire:


The USB host is connected to USB camera to capture the live video. The mini USB is used to power up the module. It's recommended to use power supply rated at 5V, 1A.

The RJ45 Ethernet port is flexible. It's default to be LAN port. User can browse to through LAN port to configure the module. User can also confgure the Ethernet port to be WAN port.


2. Why the serial port has no output?

The serial port is shown below.

During boot up process, ser2net has not started. The baud rate is 115200/8/1/N, and ASCII mode. It is used to display the startup messages. After around 30 seconds, ser2net will run. Now the baud rate is changed to 9600/8/1/N, which is used to communication with the Arduino or user's MCU.


4. What tool can be used to see the video?


The module will show up as an WiFi AP. Please connect your PC to the AO, and use firefox or Chrome, the URL is to see the video. Please don't use IE as it's NOT supported.


All socket data to port 2000 will be transparently move to the TTL UART.
