Description: 1. TTL-WiFi module is developed based on ESP-M1 WiFi module, which leads to serial port TTL, EN, STATE and other pins. 2. The latest version of Serial Port Transfer Firmware built in the product can complete the real-time data transmission from TTL port to WiFi/cloud, with low power control, status indication and other functions. 3. This module can directly replace the original wired serial port to realize data acquisition and control of embedded devices. 4. It is fully compatible with the existing electrical and physical interfaces of the bluetooth transmission module. 5. Optimized the web page configuration interface, supports AP, STA, AP+STA configuration mode, supports serial port baud rate from 300bps to 3686400bps, supports TCP Server/Client, UDP Server/Client, UDP LAN broadcast and other functions. At the same time compatible with AT command configuration, it is the most cost-effective WiFi transparent transmission product on the market. 6. The serial port receiving and transmitting performance is greatly optimized. The reconnection mechanism in WiFi STA mode and the reconnection mechanism in TCP Client mode are specially designed to ensure stable connection and transmission of the data link.
