The SmartElex E220-400M30S is a high-performance 433MHz RF breakout board powered by the next-generation LLCC68 LoRa transceiver, making it an ideal LoRa module for long-range and interference-resistant wireless communication. Operating across an exact frequency range of 410–493MHz, this module supports a maximum transmission power of 1W (30dBm), achieved through its built-in power amplifier and low noise amplifier.
Compared to standard LoRa transceivers without PA and LNA, it offers significantly improved receiving sensitivity, communication stability, and anti-interference capability. Using an industrial-grade 32MHz crystal oscillator and original imported LLCC68 chip, the module outperforms traditional FSK and GFSK solutions in both range and reliability.
As a pure RF transceiver, it requires an external MCU driver or SPI debugging tool, making it suitable for custom IoT nodes, industrial wireless systems, and long-distance data transmission projects.
