Sourcing LoRa Modules from China
1 resources tagged with "Lora"
Chinese factories build most of the world's LoRa modules, almost all around Semtech's SX127x and SX126x chips — the SX1276 is the older workhorse, the SX1262 the newer low-power part with better sensitivity and lower receive current. The detail that trips buyers is regional frequency: a module is built for a specific band (868 MHz EU, 915 MHz US, 923 MHz AS923/Japan) and must carry the matching cert (CE/RED, FCC, or TELEC). Buy the wrong band and the radio is legally useless in your market.
LoRa is the physical-layer modulation; modules wrap a Semtech chip with an MCU or SPI interface. The pitfall is sourcing a single SKU for global use, since the RF front-end and certification are band-specific; specify your region's band and required certification (CE/RED, FCC, TELEC) up front.

FAQ
What's the difference between SX1276 and SX1262?
SX1262 is newer, with lower receive current, better sensitivity, and higher output power than the older SX1276. For battery-powered or long-range nodes the SX1262 is usually the better choice; SX1276 designs are mature and cheap.
What frequency band and certification do I need?
Use 868 MHz with CE/RED in Europe, 915 MHz with FCC in North America, and 920-923 MHz (AS923) with TELEC in Japan. The module hardware is band-specific, so order the band that matches your target market.
What MOQ is typical for OEM LoRa modules?
Certified OEM modules often start around 500 units per band. Custom firmware, antenna options, or shielding can raise the minimum, and CE/RED or FCC certification adds lead time if not already held.
