Product Introduction
TTL-WiFi is designed and developed based on E SP-M2 WiFi module which is extracted the TTL, EN, STATE and other pins. Importantly, the TTL-WiFi is already built-in the serial transparent transmission firmware and programmed, which can realize the transparent transmit the data to the cloud on the real-time, together with low-power control, status indictor. This board can replace the old wiring serial WiFi device to realize the data collection and control.

Usage of Web configuration
This module is already built-in the HTTP Server. Thus, it can configure the parameters by the browsers on PC or mobile phone or other smart devices, without of need of any other tools or Apps. In the factory settings, the module works in AP mode, and the signal is ‘Doit_WiFi_xxxxxx’, where, ‘xxxxxx’ is the last 6 number of the M AC address of this module. Then, one can connect this WiFi hotspot by PCs or phones, and other smart devices (supportable Android and Ios, Windows) with no password.
Package included
3 x DT-06 Wireless WiFi Serial Port Transparent Transmission Module
