Description

The Seeed Studio Wio-LR2021 wireless module enables data transmission and reception in the 863 MHz to 928 MHz Sub-GHz band and the 2.4 GHz ISM band. It uses the Semtech LR2021 transceiver, supporting LoRa, FLRC, (G)FSK, (G)MSK, 4-FSK, O-QPSK, and LR-FHSS modulation schemes. LoRa technology provides long-range communication with low power consumption, while FLRC modulation enables data rates of up to 2.6 Mbps. The module offers receiver sensitivity down to -141.1 dBm at Sub-GHz frequencies and transmit power up to +22 dBm. It is suitable for telemetry systems, wireless sensor networks, industrial automation, smart agriculture, and IoT devices requiring communication across multiple radio frequency bands.

The Semtech LR2021 chip features a Switchless Direct-Tie RF architecture, reducing the need for external RF switches. The module supports the physical layer of protocols used in LoRaWAN, Bluetooth LE 5.0, Thread, Zigbee, Wi-SUN, and Wireless M-BUS systems. Implementing the corresponding communication protocol stacks requires an external microcontroller. The transceiver is controlled through an SPI interface, while DIO pins provide interrupt handling and additional control functions. Current consumption is 583 nA in deep sleep mode and 960 µA in idle mode, making the module suitable for battery-powered devices.

The compact SMT design measuring 17.07 x 10.42 x 2.8 mm enables direct integration of the transceiver onto a custom printed circuit board. The module provides 22 terminals, including an SPI interface, RESET and BUSY control lines, and separate RF terminals for the Sub-GHz and 2.4 GHz bands. It operates with a supply voltage of 1.8 V to 3.7 V. The Tape Reel version is designed for automated surface-mount assembly during electronics manufacturing. The manufacturer provides technical documentation, reference schematics, mechanical models, and design libraries for integrating the module into custom devices.
