LoRa Modules — Long-Range Wireless for Arduino, ESP32 & IoT
Build wide-coverage wireless networks using LoRa (Long Range) technology. Perfect for IoT, environmental monitoring, agriculture, telemetry, and remote sensor networks where WiFi and cellular are impractical.
LoRa • SX1276/SX1278 • RA-02 • Long Range • IoT • LPWAN
Why choose LoRa
- Extreme range: up to kilometers in open areas
- Ultra-low power: ideal for battery-powered IoT
- Reliable: robust modulation for noisy environments
Popular uses
- Remote weather stations
- Agricultural monitoring
- Smart city sensors
- Asset tracking & telemetry
- Long-range automation systems
Recommended add-ons

LoRa chooser (quick guide)
| Need | Best module | Notes |
|---|---|---|
| General long-range IoT communication | SX1276/SX1278 | Most common, reliable, and well-supported. |
| Small form factor + easy integration | RA-02 (Ai-Thinker) | Compact, ESP32-friendly, strong community support. |
| Maximum signal distance | LoRa + high-gain antenna | Best for farms, mountains, long corridors, etc. |
| Battery-powered sensors | Low-power LoRa modules | Ideal for multi-year deployments. |
| Dual LoRa nodes (send/receive) | Two SX127x/RA-02 units | Point-to-point or mesh networks. |
Before buying, check your local regulatory frequency band (PH commonly uses 433MHz or 915MHz LoRa modules).

FAQ
What is LoRa?
LoRa is a long-range, low-power wireless protocol used for IoT and remote sensors over 1–10 km depending on conditions.
Does LoRa need the internet?
No. LoRa is point-to-point or mesh. LoRaWAN requires a gateway but is optional.
What is the difference between SX1276 and SX1278?
The main difference is frequency band: SX1276 handles 868/915MHz; SX1278 handles 433MHz.
Do you ship nationwide?
Yes—fast PH shipping with same-day processing.
