Industrial LoRa Wireless Modules: Long-Range & Low-Power IoT Connectivity
Ebyte offers a specialized portfolio of high-performance LoRa wireless modules designed for robust and secure data transmission. Operating across global sub-GHz bands (433MHz, 868MHz, 915MHz) and 2.4GHz, our modules leverage Semtech’s advanced spread-spectrum technology to provide superior link budgets and exceptional interference immunity for long-range RF communication.
- Advanced Chipset Integration: Our series integrates industry-leading silicon, including the E22 series (SX1262) and the cost-effective E220 series (LLCC68), delivering communication distances of up to 10km+ with high receiving sensitivity.
- Versatile Hardware Interfaces: We provide flexible integration options including SPI modules for deep hardware customization and UART (TTL) modules with transparent transmission protocols for rapid development.
- Industrial-Grade Reliability: Engineered for harsh environments, these modules feature a wide operating temperature range of -40°C to +85°C, high-precision TCXO oscillators, and are compliant with CE, FCC, and RoHS standards.
- Ultra-Low Power Consumption: Optimized for battery-powered end-nodes, our low-power RF modules support multiple sleep modes and Wake-on-Radio (WOR) functionality to maximize field deployment lifespan.
1. How to Select LoRa Wireless Module?
You can quickly filter the most suitable LoRa module through the following 4 dimensions:
| Screening Dimension | Options & Corresponding Product Line |
|---|---|
| Interface Type | • UART Transparent → UART LoRa Series (plug-and-play, no RF development required)
|
| Frequency Band | • Sub-1GHz (433/470/868/915MHz) → Most long-range models, better wall penetration
|
| Transmission Range | • Short range (<3km) → E220, E53 and other low-power compact models
|
| Special Function | • Mesh self-organizing network → E52 LoRa Mesh Series
|
