Description
The EByte E220-400M30S is a professional-grade, surface-mount LoRaWAN RF module engineered for demanding IoT deployments requiring extended range and robust communication. Its architecture centers on the Semtech LLCC68 chip, a modern LoRa transceiver known for improved power efficiency and speed over previous generations like the SX1276. The module’s integrated PA and LNA significantly boost both transmit power and receiver sensitivity, ensuring reliable data links over distances up to 10 kilometers in clear line-of-sight conditions.
Designed for industrial environments, it operates across an ultra-wide 410-493MHz spectrum, supporting global license-free ISM bands at 433MHz and 470MHz. Power management is a key strength, with a wide 3-5.5V supply range and deep sleep currents as low as 1 microampere, enabling multi-year operation on battery power. The module requires an external microcontroller for configuration and data handling via its SPI interface, offering developers full control over LoRa spreading factors, bandwidth, and coding rate for optimal network performance.
