Frequently Asked Questions

Q: Is the RA-01 LoRa SX1278 433MHz module compatible with Arduino?

A: Yes! The RA-01 module communicates via a standard SPI interface, making it fully compatible with Arduino (Uno, Mega, Nano, etc.), Raspberry Pi, ESP32, ESP8266, and most other popular microcontroller platforms. Many open-source libraries such as RadioHead and LoRa.h support this module out of the box.

Q: What is the maximum transmission range of the RA-01 433MHz LoRa module?

A: In ideal open-air conditions with no obstructions, the RA-01 LoRa SX1278 module can achieve wireless transmission distances of up to 10 kilometres. Real-world range will vary depending on obstacles, antenna quality, spreading factor settings, and local RF interference.

Q: Does the RA-01 module require a licence to operate on 433MHz?

A: The 433MHz ISM (Industrial, Scientific, and Medical) band is licence-free in most countries, including much of Europe, Asia, and Australia. Always check your local regulations before deploying a wireless device, as rules can vary by region.

Q: Can I use two RA-01 modules together to create a point-to-point link?

A: Absolutely. Two RA-01 modules configured with the same frequency, spreading factor, and bandwidth settings can establish a reliable bidirectional point-to-point wireless link. They can also be used in a star or mesh network topology with appropriate firmware.
