Seeed Studio has introduced a compact yet powerful LoRa module—the Wio LR1121—that brings advanced multi-band capabilities to edge and IoT developers.
Built around the Semtech LR1121 radio transceiver chip, this new module is designed to support a wide range of frequency bands including Sub-GHz, S-band (2.1 GHz), and 2.4 GHz, expanding the possibilities for global LPWAN deployments.
A Compact Module for Global LoRa Connectivity
The Wio LR1121 measures just 15 x 12 mm, making it highly suitable for applications where space constraints are critical.
Despite its small size, it supports multiple frequency bands:
- Sub-GHz: 150 to 960 MHz
- S-Band: 2.1 GHz
- 2.4 GHz
This versatility makes the module ideal for use in various geographic regions and industries, including industrial IoT, smart agriculture, asset tracking, and smart metering.
Powered by Semtech’s LR1121 Chipset
The heart of the Wio LR1121 is Semtech’s LR1121 transceiver, which integrates multi-band capabilities in a single chip. This allows devices using the Wio module to operate seamlessly across different spectrum bands, ensuring reliable communication in diverse environments.
Key technical features include:
- LoRa, (G)FSK, and BPSK modulations
- High power efficiency for extended battery life
- Built-in temperature-compensated crystal oscillator (TCXO)
- Integrated RF switch for ease of design
Designed for Easy Integration
To simplify development, Seeed Studio offers the Wio LR1121 with a castellated pin design, making it easy to solder onto custom PCBs or development platforms. It supports AT commands via UART, allowing quick prototyping and integration without requiring deep RF knowledge.
Developers can also benefit from Seeed’s Grove ecosystem and Arduino compatibility. With comprehensive SDK and driver support, the Wio LR1121 is positioned as an excellent choice for engineers building next-generation LPWAN solutions.
Perfect Fit for Satellite IoT and Long-Range Applications
Thanks to its support for the 2.1 GHz S-band and 2.4 GHz frequency, the Wio LR1121 is particularly attractive for emerging satellite IoT applications and global asset tracking use cases. This multi-band support ensures devices remain connected whether they are in remote areas, urban environments, or crossing international borders.
Making Scalable LoRa Devices
The Wio LR1121 module represents a significant step forward for developers looking to build globally scalable LoRa devices.
With support for a broad range of frequencies in a tiny footprint, Seeed Studio continues to expand its suite of IoT solutions, making it easier for engineers to prototype and deploy reliable, long-range wireless communication systems.
