Amazon Sidewalk is a secure community network that uses Amazon Sidewalk Bridges, such as compatible Amazon Echo and Ring devices, to provide cloud connectivity for IoT devices. Amazon Sidewalk enables low-bandwidth and long-range connectivity at home and beyond using Bluetooth LE for short-distance communication and LoRa and FSK radio protocols at 900 MHz frequencies to cover longer distances. Quectel KG100S has an energy-friendly microcontroller with a high-performance 2.4 GHz radio transceiver for BLE, and a built-in long-range low power Sub-1 GHz CSS and FSK transceiver. A compact profile of 15.0mm × 15.0mm × 2.25mm and LGA form factor ensure that it can be easily embedded into size-constrained applications and provide reliable connectivity with these applications. Quectel KG100S integrates all the hardware and software resources required for Amazon Sidewalk applications. It is suitable for low flow control and data acquisition applications such as home intelligent terminal, industrial application.
