Elecrow LR2021 LoRa Module-Frequency 850~930 MHz Sub-GHz Full-Band LoRa Module (MPN:LMM16121D)

Elecrow LR2021 LoRa Module-Frequency 850~930 MHz Sub-GHz Full-Band LoRa Module

LR2021 is a compact wireless communication module powered by Semtech’s 4th-generation LR2021 LoRa chip. It supports Sub-GHz, 2.4 GHz ISM, and S-band (1900–2200 MHz), enabling flexible terrestrial and satellite communication. With up to 2.6 Mbps FLRC, -141.5 dBm sensitivity, and +22 dBm Sub-GHz transmit power, LR2021 delivers reliable long-range and high-speed connectivity. Its single-antenna multi-band design reduces BOM cost and PCB space, while the 10×10 mm compact package makes integration easy. Supporting LoRaWAN, Amazon Sidewalk, Wi-SUN, W-MBUS, Z-Wave, Thread, and Zigbee, LR2021 is ideal for global IoT, smart metering, asset tracking, industrial automation, and satellite-enabled applications.
