EByte E80-400M2213S LR1121 Dual-Band LoRa Module 433/868/915/2.4G SPI

Description

The EByte E80-400M2213S (LR1121) is a professional-grade, dual-band LoRa wireless module designed for developers requiring robust, long-range communication across multiple frequency spectrums. It integrates Semtech’s LR1121 transceiver, capable of operating on both Sub-GHz (433, 868, or 915 MHz) and 2.4 GHz bands, providing flexibility to meet regional ISM regulations and avoid congestion. The built-in SMD Temperature Compensated Crystal Oscillator (TCXO) ensures high frequency accuracy and stable RF performance across a wide operating temperature range, which is critical for reliable data links in outdoor or industrial environments.

Communication with a host processor is handled via a standard SPI interface, simplifying firmware development and integration with popular platforms like Arduino, ESP-IDF, or STM32Cube. The module’s compact form factor and IPEX stamp hole design facilitate direct antenna attachment or the use of a u.FL pigtail, optimizing the RF path for maximum range. With its low operating voltage and power-efficient LoRa modulation, this module is engineered for scalable IoT deployments in smart agriculture, industrial telemetry, asset tracking, and long-range sensor networks.
