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 […]

$200 Swarm M138 kit enables two-way satellite connectivity for IoT projects

Sparkfun has launched a Satellite Transceiver Kit based on the Swarm M138 satellite and GNSS modem that allows low-bitrate two-way connectivity for IoT projects anywhere on earth. Remote IoT applications have benefited from LPWAN standards such as LoRaWAN and NB-IoT, but in some extreme cases coverage may still be challenging, so satellite communication may be the only practical option. It used to be really expensive, but Swarm makes this more affordable, and companies like SigFox and Semtech also have (or had?) plans to use low-earth orbit satellites for their respective LPWAN technologies. Swarm M138 kit content and specifications: Swarm M138 mini PCIe satellite modem and GNSS receiver module MCU – Arm Cortex-M4 microcontroller Up to 1 Kbps data rate, up to 912 bytes packet size Frequency 137-138 MHz (downlink) 148-150 MHz (uplink) Dimensions – 51.0 x 30.0 x 5.3 mm Weight – 9.6 grams Temperature Range – -40°C to +85°C […]

DeNova Detect natural gas alarm works with Amazon Sidewalk network

Denova Detect Amazon Sidewalk natural gas alarm

New Cosmos’ DeNova Detect is a wireless natural gas alarm that works with the Amazon Sidewalk network designed for low-power, low-bandwidth IoT devices in and around the house, benefiting from free connectivity thanks to the installation base of Amazon devices such as the Echo Show acting as gateways. DeNova Detect does not require wiring to mains, and the device is expected to achieve an extended battery life of seven years, so customers can choose the optimal location for a gas alarm in their homes without needing to be close to an electrical outlet. There’s no need to have an additional gateway such as with LoRaWAN solutions as well as the customer owns one or more Sidewalk-compatible device. Note that Amazon Sidewalk is currently deployed in the US only with global expansion planned for later. Amazon Sidewalk relies on Bluetooth LE inside the home, Sub-GHz GFSK on the sidewalk/around […]
