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.\u003c\/p\u003e\n\u003ch4\u003eQ: Is the HC-14 module compatible with Arduino and Raspberry Pi?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the working frequency range of the HC-14 module?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I use one module as a transmitter and one as a receiver?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
