SparkFun Thing Plus – ESP32-C5 board offers dual-band WiFi 6, Adafruit Feather pinout, LiPo battery support
Espressif has recently released the ESP-IDF v6.0 framework with support for ESP32-C5 and ESP32-C61, so we can expect more ESP32-C5 boards. Following the launch of boards like DFRobot FireBeetle 2 and the Espressif DevKitC-1, SparkFun has now launched its Thing Plus – ESP32-C5, an Adafruit Feather-compatible board based on the ESP32-C5. The timing is no coincidence. Although the ESP32-C5 dual-band WiFi 6 SoC was announced back in 2022, hardware makers have been waiting for stable software support. With the release of ESP-IDF v6.0, the ESP32-C5 moves from “preview” to “stable” and adds key features, such as Safe Bootloader OTA updates. This enables the ROM bootloader to fall back to a recovery partition if an update fails, making it reliable enough for companies like SparkFun to launch hardware for remote deployments and Matter-compatible smart home applications. SparkFun Thing Plus – ESP32-C5 specifications: Wireless module – ESP32-C5-WROOM-1 SoC – Espressif Systems ESP32-C5 CPU Single-core […]

LR2021 LoRa Plus board combines Semtech LR2021 and Nordic nRF54L15 for high-speed FLRC and LoRa connectivity
Last year, Semtech released the 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.
