Basic Manual
DT-06 (TTL-WiFi module) is designed and developed based on ESP-M2 WiFi module from our company Shenzhen Doctors of Intelligence & Technology Co., Ltd., which is extracted the TTL, EN, STATE and other pins. Importantly, the TTL-WiFi is already built-in the serial transparent transmission firmware programmed by our company (SZdoit), 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. It has the following features.
- Fully compatible with the original electrical interface and physical interface for the serial transparent Bluetooth;
- Built-in the industrial transparent transmission firmware V3.0 with stability and reliability by using the Web Configuration;
- Built-in the high performance WiFi module ESP-M2 with size: 34mm17mm4mm;
- Working voltage: 4.5V~6.0V, TTL working voltage: 3.3V (compatible with 5.0V);
- Provided pins: STATE, TXD, RXD,EN;
- Average current: 80mA; when data sent, it is 170mA; but it is 20μA at deep sleep mode;
- Support serial AT command;
- Support re-programmable, OTA firmware update;
- Seamless transparent transmission between serial and WiFi;
- Built-in HTTP Web Server, support configure parameters by web page;
- Support re-connect automatically at WiFi STA mode and TCP Client;
- Support set baud rate, data bit, parity check, stop bits, and/or subcontracting time;
- Support baud rate (bps): 300/600/1200/2400/4800/9600/19200/38400/57600/74800/115200/
- 230400/460800/921600/1843200/3686400；
- Support AP enable, self-defined SSID/password, self-defined IP and network duration;
- Automatically scan the peripheral WiFi hotspot, support STA enable, DHCP, self-defined IP;
- Support TCP Server, TCP Client, UDP Server, UDP Client and UDP local broadcast;
- Support DNS resolution automatically for the remote sever address;
- Support checking the status by AT command;
- Provide IO4 to show the WiFi status;
- Working temperature: -40℃-125℃;
- Applications: smart home, wireless data connection and transparent transmission, smart car control, wireless serial printer, LED light industrial control etc.
