Frequently Asked Questions
Q: What communication protocol does the HC-14 LoRa wireless module use?
A: The HC-14 uses transparent serial (UART) communication. This means it acts as a wireless serial wire — data sent to one module's TX pin is received at the other module's RX pin, requiring no special protocol or complex coding on your microcontroller.
Q: Is the HC-14 module compatible with Arduino and Raspberry Pi?
A: Yes. The HC-14 operates on DC 3.0–5.5V, making it fully compatible with both 5V Arduino boards and 3.3V Raspberry Pi GPIO pins. Simply connect it to your serial UART interface to get started.
Q: What is the working frequency range of the HC-14 module?
A: The HC-14 operates within the 415–450 MHz frequency band, commonly referred to as the 433 MHz LoRa band. It transmits at 100 mW (20 dBm) for reliable longer-range wireless data transfer.
Q: Can I use one module as a transmitter and one as a receiver?
A: Yes. Since this listing includes 2 modules, you can configure one as a transmitter and the other as a receiver, or use them in a bidirectional transparent serial link — perfect for point-to-point wireless communication projects.
