DT-06 WiFi to TTL Serial Transparent Transmission Module (ESP-M2, HC-06 Footprint)

The DT-06 WiFi to TTL Serial Transparent Transmission Module is a compact wireless bridge built around the ESP-M2 (ESP8285) WiFi chip, designed to convert any UART serial connection into a WiFi link. It drops straight into projects that already use an HC-06 Bluetooth module, since it shares the same pinout and physical footprint.

Key features:

• ESP-M2 WiFi Core: Built on the ESP8285-based ESP-M2 module, supporting 802.11 b/g/n on the 2.4GHz band.
• Transparent Transmission: Built-in firmware forwards serial data over WiFi in real time with no extra coding required.
• HC-06 Pin-Compatible: Matches the classic Bluetooth module footprint, so it can drop into existing HC-06 wiring.
• Flexible Network Modes: Supports AP, STA, and combined AP+STA modes with a built-in web configuration page.
• Status Indicator: Onboard LED and STATE pin report the current connection status at a glance.
• Wide Input Tolerance: Operates from 4.5V to 6V while keeping TTL logic at a safe, 5V-tolerant 3.3V.

Ideal for adding WiFi control to Arduino, robotics, and IoT projects that need wireless serial communication without redesigning existing Bluetooth wiring.
