Full support for Amazon Sidewalk
Quectel’s KG100S is a low-power, cost-effective module in an LGA form factor which is developed specially to support Amazon Sidewalk applications. Amazon Sidewalk is a shared wireless network that uses Amazon Sidewalk Bridges, such as compatible Amazon Echo and Ring devices, to provide cloud connectivity for IoT devices. Amazon Sidewalk enables reliable, low-bandwidth, and long-range connectivity at home and beyond, using Bluetooth® Low Energy for short-distance communication and LoRa® and FSK radio protocols at 900MHz frequencies to cover longer distances.
The KG100S is equipped with a built-in SX1262 transceiver supporting LoRa® and FSK and a high-performance, energy-friendly Silicon Labs EFR32BG21B microcontroller with a 2.4GHz radio transceiver for Bluetooth® Low Energy 5.1 and 80MHz ARM Cortex-M33 microcontroller core. With a compact profile of 15mm × 15mm × 2.25mm, 96KB of RAM and 1MB Flash, the module has a 3.3V and 1.8V power supply and is suitable for connecting low data rate applications such as sensor networks and smart home devices.
The KG100S integrates all the hardware and software resources required for Amazon Sidewalk. The module is designed to support either a hosted or hostless system architecture where developers can customize the provided sample applications to support a multitude of sensors, actuators and use cases such as smart locks, door sensors, gas and water leak detection, pet tracking, connected appliances, indoor air quality sensors, HVAC monitoring, smart parking and traffic monitoring, utility metering, waste management, air quality monitoring, flood management, and tracking assets such as pallets and returnable packaging.
