Develop Smart IoT Devices with Our SAM D21 Curiosity Nano Evaluation Kit and Amazon’s Alexa Connect Kit (ACK)


Quickly build Internet of Things (IoT)-enabled smart devices controlled by Amazon’s Alexa service via voice commands and mobile applications. The combination of Amazon’s Alexa Connect Kit (ACK) and our SAM D21 Curiosity Nano Evaluation Kit provides an easy, cost-effective solution to bring your product to market rapidly.

ACK is a managed service that makes it easy to integrate Alexa into your product. It eliminates the need to create an Alexa skill, manage a cloud service or develop complex network and security firmware to connect your product to Alexa. You simply pay a one-time fixed cost to integrate the ACK module into your product and provide your customers with an exceptional voice-controlled user interface.

The SAM D21 is a low-power 32-bit Arm® Cortex®-M0+ based Host Microcontroller (HMCU) that is ideal for use in a wide range of home automation, consumer, metering and industrial applications. Its key features include:

  • Flexible package options ranging from 32–64 pins
  • 256 KB Flash and 32 KB SRAM
  • Maximum operating frequency of 48 MHz
  • Flexible SERCOM modules and intelligent peripherals such as an Event System for inter-peripheral signaling without using CPU bandwidth
  • Supported by MPLAB® Harmony v3 software framework and MPLAB X Integrated Development Environment (IDE) for rapid prototyping

SAM D21 Curiosity Nano Evaluation Kit

Part Number: DM320119

Featuring a SAMD21G17D MCU, the SAM D21 Curiosity Nano Evaluation Kit is a low-cost solution for taking your 32-bit embedded application from proof of concept to production. It features a virtual COM port (CDC) for serial communication to a host PC and a Data Gateway Interface (DGI) GPIO. Because it includes an on-board Nano Debugger, no external tools are necessary to program the MCU.
