XCVR LoRa-based IoT development board & reference design features SX1261, SX1262, or LLCC68 chip

Semtech Corporation and “Connected Development” engineering firm have launched the XCVR development board and reference design based on Sentech SX1261, SX1262, or LLCC68 transceivers with the last one targeting Smart Home applications. The XCVR development board is actually an Arduino shield that’s been tested with Nordic nRF52840-DK board, but should work with most boards equipped with Arduino Uno headers. It can be used for the design of LPWAN IoT applications using SX1262x transceivers such as smart meters, industrial controllers, asset tracking, building automation, smart agriculture, etc… while the LLCC68 model is more useful for Smart Home applications and consumer devices. XCVR shield specifications and features: LoRa and FSK Modem Programmable bit rate up to 62.5 kbps LoRa and 300 kbps FSK External antenna Link budget 163 dB maximum for SX1261 170 dB maximum for SX1262 configurations. Tx Power +15 dBm high-efficiency PA for SX1261 +22 dBm or +15 dBm high-efficiency […]

HARDWARIO CHESTER – A configurable Zephyr OS LPWAN IoT gateway with LoRaWAN, LTE IoT, GNSS connectivity

HARDWARIO CHESTER platform is a configurable LPWAN IoT gateway whose main function is to connect as many devices and environments as possible to the Internet using connectivity such as LoRaWAN, LTE Cat M1, or NB-IoT, as well as GNSS for geolocation. Contrary to most IoT gateways, it does not run Linux on an application processor, and instead, the “brain” of the CHESTER IoT gateway is a Raytac Bluetooth 5.0 module based on a Nordic Semi nRF52840 Arm Cortex-M4 microcontroller running Zephyr real-time operating system, which connects to LTE IoT modem and a LoRaWAN module through UART, and expansion modules through I2C, 1-wire, and GPIO interfaces. HARDWARIO CHESTER specifications: Wireless modules/chips Raytac MDBT50Q-P1MV2 Bluetooth 5.0 module based on Nordic Semi nRF52840 Arm Cortex-M4F MCU with 1MB Flash memory, 256kB RAM Nordic Semi nRF9160-SICA-B1A-R7 LTE-M/NB-IoT system-in-package (SiP) with Arm Cortex-M33 MCU, 1024 KB flash, 256 KB SRAM Murata CMWX1ZZABZ-078 LoRa module as […]

Embit EMB-LR1280-mPCIe-4x is a 2.4GHz LoRa mPCIe module based on Semtech SX1280 chipset

Embit EMB-LR1280-mPCIe-4x is an mPCIe (mini PCIe) module based on four Semtech SX1280 2.4 GHz LoRa transceivers and designed for OEM gateways that can work worldwide thanks to the use of the 2.4GHz ISM band and supports ranging. We first covered 2.4GHz LoRa and the SX1280 transceiver two years ago as a solution to design region-independent products specially suited to maritime and intercontinental logistics applications. We haven’t seen it used that much although we covered an ESP32 board with SX1280 last year, and it turns out that Italian company Embit has also made a mPCIe module based on the SX1280 chipset. Embit EMB-LR1280-mPCIe-4x specifications: LoRa connectivity Chipsets – 4x Semtech SX1280 transceiver with 3x LoRa Rx Channels + 1x LoRa Tx Modulation – LoRa Spread Spectrum Frequency – 2.4 GHz ISM band Frequency Range – 2400 to 2500 MHz RF Output power – Up to +12 dBm Sensitivity -129 dBm […]

433 MHz is not dead! Using an ESP32 board with LoRa module to talk to 433 MHz sensors

CNXSoft: This is a guest post by Florian Robert (1technophile) of the OpenMQTTGateway project about using a 433 MHz LoRa transceiver on an ESP32 board for home automation, specifically to talk to 433 MHz sensors Everyone is talking about Matter, Bluetooth, Zigbee, and Zwave, but before these complex communication technologies, we had one simple, robust one that our sensors and devices used to leverage: 433MHz. It may be too simplistic to talk about 433 MHz as a technology as there are different and various usages of this frequency. You can find it being used in numerous devices around your home, from your outdoor temperature sensors, and security sensors to the tire pressure sensors in your car. If we want to be specific, we can talk about the different radio frequencies (433 MHz, 915MHz, 868MHz, 315MHz, or 350MHz) and signal modulations OOK, ASK, FSK that we encounter behind the keyword 433MHz.
