DT-06 WiFi Serial TTL Module — Transparent Transmission, HC-06 Compatible, ESP-M2

The DT-06 is a compact WiFi serial transparent transmission module built on the ESP-M2 (ESP8266) chip. It is designed as a drop-in replacement for the Bluetooth HC-06 module — sharing the same 4-pin footprint (VCC, GND, TX, RX) and transparent serial bridge behavior, but transmitting data over WiFi instead of Bluetooth. This makes it ideal for upgrading existing HC-06 Arduino projects to WiFi without code changes.

DT-06 vs HC-06 — WiFi Upgrade Path

Feature	DT-06 (WiFi)	HC-06 (Bluetooth)
Protocol	WiFi (TCP/UDP)	Bluetooth Classic
Range	Up to 100m (WiFi)	~10m
iOS Compatible	✅ Yes (via TCP)	❌ No
Pin Layout	Same as HC-06	Standard
Configuration	AT commands / web page	AT commands

Why Choose DT-06?

✅ HC-06 pin compatible — swap into existing HC-06 socket without PCB changes
✅ WiFi range — up to 100m vs 10m for Bluetooth
✅ iOS compatible — connect from iPhone via TCP socket app
✅ 3.3V / 5V supply — onboard LDO, works with 5V Arduino directly
✅ Web configuration — set SSID/password via browser, no AT commands needed
