The DT-06 is a compact Wi-Fi-to-TTL serial module based on the ESP8285 — essentially an ESP8266 with 1 MB of built-in SPI flash. It provides a simple way to add Wi-Fi connectivity to any microcontroller project via a UART serial interface, using AT commands or custom firmware.

The module supports Station, SoftAP, and combined modes, and is fully compatible with ESP8266 development tools and libraries. Its extended operating temperature range (−40 to +125 °C) makes it suitable for industrial and harsh-environment applications.
