Our Review
After integrating the 433MHZ SX1278 LoRa Module 433M 10KM Ra-02 Wireless Spread Spectrum Transmission Board 2.4G IPX Antenna for Smart Home into several test builds, we found it to be a capable component for the price. Key specs include Frequency: 433MHZ, Range: up to 5km, TX Power: +20 dBm max.
Range testing in a suburban environment reached approximately 3km with clear line of sight using the stock PCB antenna. Switching to an external SMA antenna extended this significantly.
The LoRa modulation provides excellent noise immunity, making it ideal for sensor networks spread across a farm, campus, or building complex.
For the price point, the 433MHZ SX1278 LoRa Module 433M 10KM Ra-02 Wireless Spread Spectrum Transmission Board 2.4G IPX Antenna for Smart Home delivers what you need without unnecessary complexity. Recommended for hobbyists and engineers working on projects where communication modules components are essential.
