Adafruit QT Py - SAMD21 Dev Board with Stemma QT

Key Features:

• Runs Arduino like a dream, and can be used for basic CircuitPython projects.
• Use any SparkFun Qwiic boards! Seeed Grove I2C boards will also work with this adapter cable.(not included)
• Same size, form-factor, and pin-out as Seeed Xiao
• ATSAMD21E18 32-bit Cortex M0+ - 48 MHz 32 bit processor with 256KB Flash and 32 KB RAM
• USB Type C connector

What a cutie pie! Or is it... a QT Py? This diminutive dev board comes with our favorite lil chip, the SAMD21 (as made famous in our GEMMA M0 and Trinket M0 boards).

This time it comes with our favorite connector - the STEMMA QT, a chainable I2C port that can be used with any of our STEMMA QT sensors and accessories.

OLEDs! Inertial Measurment Units! Sensors a-plenty. All plug-and-play thanks to the innovative chainable design: SparkFun Qwiic-compatible STEMMA QT connectors for the I2C bus so you don't even need to solder! Just plug in a compatible cable and attach it to your MCU of choice, and youre ready to load up some software and measure some light.
