Dual-band LoRa communication module based on the LR1121 transceiver, supporting Sub-GHz 410-510MHz and 2.4GHz bands, with SPI interface, AES-128 encryption and integrated TCXO. LF version without pre-soldered pin headers, intended for soldered mounting. Waveshare Core1121-LF
Description
The Waveshare 31901 Core1121-LF LoRa module is designed for low-power wireless communication in LPWAN networks, for IoT applications requiring long range, high reliability and operation across multiple frequency bands. The design is based on the third-generation low-power LR1121 transceiver, enabling transmission in Sub-GHz and 2.4GHz ISM bands, allowing flexible adaptation to local radio regulations and deployment scenarios.
The module supports LoRa, (G)FSK and LR-FHSS modulation schemes, ensuring compatibility with earlier solutions based on SX126X, SX127X and SX128X series transceivers. Communication with the host microcontroller is handled via the SPI interface, enabling integration with popular platforms such as ESP32, Raspberry Pi, STM32 and Raspberry Pi Pico.
The integrated TCXO oscillator improves frequency stability across a wide temperature range, while the hardware AES-128 encryption engine enhances data security in LoRa and LoRaWAN networks. The version without pre-soldered pin headers is intended for direct PCB mounting or applications requiring a custom connector selection.
