  "textContent": "Last year, Semtech released the Semtech LR2021 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 the LR2021 LoRa Plus development Kit targeting 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 with Arduino Uno, STM32 Nucleo, and Nordic DK [...]\n\nThe post LR2021 LoRa Plus board combines Semtech LR2021 and Nordic nRF54L15 for high-speed FLRC and LoRa connectivity appeared first on CNX Software - Embedded Systems News.",
