(+1Month Warranty) Ra-01 SX1278 LoRa Module AI Thinker 433MHz Long Range SPI Wireless Transceiver for Arduino IoT

Anxinke LoRa Series Modules (Ra-01 / Ra-02)

The Anxinke LoRa series modules are designed and developed by Anxinke Technology. These modules use the SX1278 RF chip, which integrates a LoRa™ long-range modem for ultra-long-distance spread spectrum communication. The modules offer strong anti-interference capabilities and minimize power consumption.

Leveraging SEMTECH’s patented LoRa™ modulation technology, the SX1278 features:

High sensitivity: up to -148 dBm

Output power: +20 dBm

Long transmission distance and high reliability

Compared with traditional modulation technologies, LoRa™ provides better anti-blocking and selectivity, solving the common trade-offs between distance, anti-interference, and power consumption.

Frequency: 433 MHz (Ra-01, Ra-02), mainly for 433 MHz networks in China and Southeast Asia.
