LR2021 LoRa Plus board combines Semtech LR2021 and Nordic nRF54L15 for high-speed FLRC and LoRa connectivity

Semtech LR2021 LoRa Development Board

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. 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 boards. […]

LilyGO T-Display S3 Pro LR1121 devkit adds Sub-GHz and 2.4GHz LoRa, audio support

T Display S3 Pro LR1121

LilyGO has recently released the T-Display S3 Pro LR1121, a new ESP32-S3 development kit with a Semtech LR1121 transceiver for universal LoRa connectivity across the sub-GHz and 2.4GHz bands. The board is an update to the earlier T-Display S3 Pro, which features a slimmer design and a 2.33-inch touchscreen display, but this new LR1121 variant adds sub-GHz and 2.4 GHz LoRa/(G)FSK support along with a voice communication kit that includes a MAX98357A I2S speaker amplifier, a PDM/I2S digital microphone, vibration motor, and a RTC. There are also programmable buttons, Qwiic connectors, and a 1/4-inch tripod mount, as well as a 2000 mAh Li-ion battery, USB-C for power, and ultra-low sleep current. These features make it suitable for applications such as LoRa walkie-talkies, Meshtastic nodes, voice-enabled IoT devices, portable dashboards, and experimental long-range wireless systems. T-Display S3 Pro LR1121 specifications: Wireless MCU – Espressif ESP32-S3R8 CPU – Dual-core Tensilica LX7 microcontroller […]

LILYGO T-Beam 1W – An ESP32-S3 + SX1262 high-power LoRa dev board with 32 dBm output, GNSS support

LILYGO T Beam 1W

The LILYGO T-Beam-1W is an ESP32-S3-based high-power LoRa development board featuring an SX1262 RF transceiver, an onboard 1W power amplifier (32 dBm), a L76K GNSS module, a 1.3-inch SH1106 OLED, a microSD slot, USB-C, Qwiic connectors, and an AXP2101 PMU. The board runs on a 7.4V battery and includes a cooling fan for high-power RF operation. We first wrote about the original LILYGO T-Beam (then branded as TTGO) in 2018, and since then, the company introduced various revisions of the T-Beam as it became popular. The T-Beam 1W is the most powerful version so far, with a built-in 1 Watt amplifier that allows the board to transmit data over longer distances without needing to buy separate, bulky amplifiers. LilyGO T-Beam-1W Specifications: Core module – Espressif Systems ESP32-S3-WROOM-1 SoC – ESP32-S3 CPU – Dual-core LX7 processor with up to 240MHz Memory – 512KB SRAM, 8MB PSRAM Storage – 384KB ROM Wireless – […]

LoRa, BLE, and GNSS tracker supports open-source software, solar charging, outdoor and indoor tracking

Ruictec's TD04 Asset Tracker

Designed by Ruictec in China, the TD04 is a LoRa-based low-power tracker that also features BLE and dual-band GNSS. It supports both indoor and outdoor positioning, and is suitable for fleet management, asset tracking, and geofencing over public or private LoRaWAN networks with minimal maintenance. The device combines GNSS (L1/L5) for outdoor positioning with BLE-based indoor tracking. It automatically switches between the two to optimize accuracy and power usage, delivering around 1–2 m accuracy outdoors and 2–4 m indoors. It is LoRaWAN 1.0.3-compliant, supports OTAA and ABP, and operates across multiple regional bands (EU868, US915, IN865, AS923, and others). Other features include a built-in motion sensor (G-sensor), configurable reporting and heartbeat intervals, iBeacon support, optional Bluetooth gateway mode, BLE-based configuration, OTA updates, and batch firmware upgrades. The device is powered by a 6000 mAh rechargeable battery and support 1.3 W solar panel input, enabling up to six months of standby […]

Giveaway Week 2025 – RAKwireless Blues.ONE LoRaWAN, LTE-M, and NB-IoT devkit

Blues.ONE LTE-M NB-IoT devkit

It turns out we don’t have two, but three companies offering free samples on CNX Software this year. The last one is a regular, and RAKwireless joins us for the fifth year running with a Blues.ONE LoRaWAN, LTE-M, and NB-IoT devkit that can be useful for industrial automation and asset-tracking applications. Regular readers may recall that it is the same prize as last year. While I usually prefer getting a new devkit, the company didn’t launch any this year (just some Meshtastic kits). The good news is that if you missed out last time around, you have a chance to give it another go. Here’s what the winner will get as a reminder: RAK4631 WisBlock Core Module based on Nordic Semi nRF52840 Arm Cortex-M4F microcontroller @ 64 MHz with 1 MB Flash, 256 KB RAM, Bluetooth Low Energy 5.0 protocol stack Semtech SX1262 LoRa Transceiver with LoRaWAN 1.0.2 protocol stack […]
