Waveshare Core2021-LF Dual-Band LoRa Module, LR2021 Transceiver 410-510MHz

Description

The Waveshare Core2021-LF module integrates Semtech’s fourth-generation LR2021 multi-band transceiver, engineered for scalable LPWAN and industrial IoT systems. Its dual-band architecture supports the 410–510 MHz LF spectrum alongside 2.4GHz ISM bands, providing developers with frequency agility for global compliance and interference mitigation. The chip’s multi-protocol radio core handles LoRa, FLRC, FSK, BLE, and ZigBee modulation, allowing a single hardware platform to serve diverse wireless topologies from star networks to mesh.

Designed for low-power operation, the module delivers a maximum RF output of 22dBm in the Sub-GHz band while maintaining efficient current consumption, critical for solar-powered or battery-operated remote sensors. The integrated TVS protection and IPEX-4 connector with castellated pads ensure reliable antenna coupling and ESD resilience in harsh environments. With its compact 19x22mm footprint and comprehensive driver support for popular embedded platforms, the Core2021-LF accelerates development of telemetry, automation, and environmental monitoring solutions requiring kilometer-scale wireless reach.
