Prototype Your 32-Bit Embedded Application at a Fraction of the Cost Using the SAM D21 Curiosity Nano
Jumpstart your next embedded product from proof of concept to production with our Arm® Cortex® M0+ based SAM D21 Curiosity Nano Evaluation Kit.
Most embedded starter kits try to demonstrate all the features of a microcontroller (MCU) family, requiring the kit to contain additional hardware like displays, communication buses, transceivers and more. This “one size fits all” approach ends up ballooning the cost of an embedded development platform. But Microchip’s Curiosity Nano embedded evaluation kit is a self-contained and modular board that interfaces with a range of mikroBUS™ and XPro expansion boards, allowing you to quickly scale and customize your development platform with relevant and re-usable add-on hardware — thereby reducing your prototyping efforts and costs. In addition, the same add-on hardware can interface with other Curiosity Nano embedded evaluation kits, allowing you to explore Microchip’s wide range of MCU offerings.
About the SAM D21 Curiosity Nano Evaluation Kit
Microchip’s SAMD21G17D Curiosity Nano evaluation kit (DM320119) is a hardware platform to evaluate the ATSAMD21G17D MCU, and it is supported by Microchip’s MPLAB® X Integrated Development Environment (IDE). This enables access to Microchip’s Embedded Software Development Framework, MPLAB Harmony v3, which provides flexible and interoperable software modules to help simplify the development of value-added features. The evaluation kit is compatible with Microchip’s Curiosity Nano Development Platform and provides easy access to the specific features of the SAMD21G17D relevant to your custom embedded application. The board comes with an on-board debugger which also features a virtual COM port (CDC) for serial communication to a host PC and a Data Gateway Interface (DGI) GPIO.
Features of the SAMD21G17D Curiosity Nano evaluation kit include:
> SAMD21G17D – Arm® Cortex® M0+ based 32-bit MCU
> One user LED (yellow) and user switch
> On-board Nano programmer / debugger
- Programming and debugging
- Board identification in MPLAB X IDE
- One green power/status LED
- Virtual COM port (CDC)

Demo Example without Expansion Board
Getting started with SAM D21 Curiosity Nano using MPLAB Harmony v3
This application demonstrates a periodic LED toggle and prints the LED toggling rate on the serial terminal. The periodicity of the timeout will change from 500 milliseconds to one second, two seconds, four seconds and back to 500 milliseconds every time you press the switch SW0 on the SAM D21G17D Curiosity Nano Development Board.
Demo Example with Expansion Board
This demo example demonstrates a SAMD21 based embedded application which sends a distress signal in the event of a personal emergency by sending a location-tagged SOS SMS. This application demo uses:
- SAM D21 Curiosity Nano Evaluation Kit (DM320119)
- GSM-GPS Click Board ( https://www.mikroe.com/gsm-gps-click )
- Curiosity Nano Base for Click boards (AC164162)
- Li-ion or LiPo Battery (optional)
The Mikroelektronika GSM-GPS click board, contains a hardware module that combines the GSM/GPRS and GPS functionality used for tracking the device and sending out the emergency or distress signal. The MCU is interfaced with the GPS module over the UART interface to perform the acquisition and tracking of GPS coordinates. It registers the event callbacks for location tracking of the GPS receiver.
The application arranges the GSM/GPRS module for sending SMS to a configured mobile phone number.
Once the GPS position is available, the application sends a location tagged SOS SMS to the configured mobile phone number when emergency switch is pressed. The application also provides feature to configure a cell phone number to send SMS every time the switch on the board is pressed for more than four seconds.
The SAMD21 Curiosity Nano evaluation kit quickly develops embedded applications ranging from simple timer-based tasks to complex communication tasks.
