SmartElex E220-400M30S 433MHz 1W LoRa RF Breakout Board

SmartElex E220-400M30S 433MHz 1W LoRa RF Breakout Board

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.

Features:

• The measured distance can surpass ten kilometers.
• Built-in PA+LNA, significantly enhancing communication distance and stability;
• The maximum transmission power is 1W, and the software has multiple levels of adjustment;
• Support the global license-free ISM 433/470MHz band.
• In LoRaTM mode, the data transmission rate is 1.76kbps to 62.5kbps.
• FSK mode provides up to 300kbps data transmission rate.
• FIFO has huge capacity and offers a 256-byte data cache.
• Support the spread spectrum factors SF5, SF6, SF7, SF8, SF9, SF10, and SF11;
• Support A power supply of 3 ~ 5.5V, or higher than 3.3V, provides optimal performance.
• The industrial standard design allows for long-term use at temperatures ranging from 40 to 85 degrees Celsius.
