Works with Amazon Sidewalk

Amazon Sidewalk is a secure wireless community network that uses Amazon Sidewalk Gateways (also called Sidewalk Bridges), such as compatible Amazon Echo and Ring devices, to provide cloud connectivity for IoT endpoint devices.
Amazon Sidewalk enables 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 XIAO nRF52840 is a wireless module qualified for Amazon Sidewalk, providing IoT device connectivity via Bluetooth Low Energy radio technology on Amazon Sidewalk network.

?Ultra-small Size?21 x 17.5mm, Seeed Xiao series classic form-factor for wearable devices. Part List: Seeed XIAO BLE nRF52840*1/7 Pins Header*2. ?Ultra-low Sleep Power?5 µA, deep sleep model with battery charging chip: BQ25101 chip supported lithium battery charge management. ?Rich Interface?Firstly, the Near Field Communication(NFC) is functional on the board. Secondly, there is a tiny and elegant reset button on one side of the Type-C interface. On the other side, it is designed in a three-in-one LED along with power LED. It supports UART, IIC, and SPI all three common serial ports. Same as Seeed XIAO RP2040, it has an onboard 2 MB flash which means it can also be programmed by Arduino, MicroPython, CircuitPython, or other program languages. ?Wireless Capabilities?XIAO nRF52840 has Bluetooth 5.0 NFC module with an onboard antenna. With the capabilities of wireless connection, it still remains the Seeed XIAO series classic form-factor of small and exquisite which can be used for wearable devices and Internet of Things projects. ?Powerful CPU?As the first wireless product in the Seeed XIAO family, Seeed Studio XIAO nRF52840 has equipped a powerful Nordic nRF52840 MCU which is designed in a Bluetooth 5.0 module, built around 32-bit ARM Cortex-M4 CPU with Floating-Point Unit(FPU) operating at 64Mhz.
