• Last year, Semtech released theLR2021 LoRa Plus transceiver chip, designed to address the low data-rate issue associated with LoRa, but surprisingly, they didn’t release a development board for the chip. • Now, almost a year later, Seeed Studio and Semtech have partnered to introduce theLR2021 LoRa Plus development kittargeting long-range high-speed LoRa and FLRC applications up to 2.6 Mbps. • Not only does the board support LoRa Gen 4 technology, providing Sub-GHz, 2.4 GHz ISM, and S/L-band operation, but a XIAO nRF54L15 board also adds dual-core processing (Arm Cortex-M33 + RISC-V) and supports other short-range protocols, including NFC, Bluetooth LE 6.0, Matter, Thread, and 2.4 GHz proprietary protocols. • The development board also features a 0.96-inch 128×64 OLED, three Grove connectors for expansion, a USB Type-C for power, SWD debugging, and two Sub-GHz and 2.4 GHz SMA connectors. • It is compatible withArduino Uno,STM32 Nucleo, andNordic DKboards. • It also features Fast Channel Activity Detection (CAD) for lower power consumption during channel sensing, making it suitable for global asset tracking, high-speed OTA updates, converged short- and long-range networking, as well as low-power audio and image transmission use cases.
Article Summaries:
- Seeed Studio and Semtech have launched a new LR2021 LoRa Plus development kit that pairs Semtech’s LR2021 transceiver with Nordic’s nRF54L15 SoC. The board supports high‑speed LoRa and FLRC up to 2.6 Mbps, plus Sub‑GHz, 2.4 GHz ISM, and S‑band operation. Dual‑core processing (Cortex‑M33 + RISC‑V) enables short‑range protocols such as Bluetooth LE 6.0, Matter, Thread, NFC, and proprietary 2.4 GHz modes. Features include a 0.96‑inch OLED, Grove connectors, USB‑C power, dual SMA antennas, and low‑power Fast CAD. It targets global asset tracking, OTA updates, converged networking, and low‑power audio/image transmission.
