Our Review
The Comimark 2Pcs LoRa SX1278 Long Range RF Wireless Power Mental Module SX1276 5Km for Arduino delivers solid performance for its category. With Frequency: 433MHz, Range: up to 15km (open field), TX Power: +17 dBm, it covers the essentials that most makers and engineers need for their projects.
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.
Overall, the Comimark 2Pcs LoRa SX1278 Long Range RF Wireless Power Mental Module SX1276 5Km for Arduino fills its role well. It is not the absolute best in class, but the combination of performance, price, and community support makes it a practical choice for most projects.
