Frequently Asked Questions
Q: Is the DT-06 WiFi module a direct replacement for the HC-06 Bluetooth module?
A: Yes — the DT-06 is designed with an HC-06-compatible pinout, so it can be used as a hardware drop-in replacement. You may need to update your software to connect via WiFi instead of Bluetooth, but the physical wiring remains the same.
Q: What microcontrollers is the DT-06 TTL WiFi module compatible with?
A: The DT-06 uses a standard TTL UART interface (TX, RX, VCC, GND) and is compatible with Arduino, Raspberry Pi, STM32, AVR, and virtually any microcontroller or development board that supports serial UART communication.
Q: How do I configure the DT-06 WiFi serial module?
A: The DT-06 supports AT command configuration via its serial interface. You can set parameters such as WiFi SSID, password, baud rate, and operating mode (STA/AP/STA+AP) using a serial terminal or your microcontroller's UART port.
