16 Channel Wifi Relay Module

Control up to 16 Devices remotely using this Wifi & Ethernet capable 16 channel relay module.

Specifications:

Supports AP/STA
Supports TCP Server/TCP Client/UDP Server/UDP Client Modes
No driver required, just use as a normal serial port from your computer
Dimensions: 115mm x 130mm x 19mm
Low power Wifi Module
Compared with traditional dynamic domain name plus router port mapping this device has incomprable superiority by eliminating the need for users to apply for a dynamic domain name, it makes frequent operations, such as port mapping on the router, so the device has plug and play capabilities.

Usage:

When first powered up, the modue will setup an access point named HI-LINK_XXXX, where XXXX changes module by module. The default password to the SSID is 12345678. To configure the module, first connect the PC to the access point created by the module HI-LINK_XXXX, and then point the browser to: http://192.168.16.254/ser2net.asp.

The P2P device is referred by to the uuid and password. To find out the uuid and set the password, point your brower to: 192.168.16.254/p2p.asp when we connect the PC to the access point created by the module HI-LINK_XXXX. The browser will prompt for username and password to access the configuration page, where the default username 'admin', and password is 'admin'.

We can then control the relays using the app by referring to the uuid, and provide password.
