Adafruit QT Py - SAMD21 Dev Board

Description:

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).

Pinout and shape is Seeed Xiao compatible, with castellated pads so you can solder it flat to a PCB. In addition to the QT connector, we also added an RGB NeoPixel (with controllable power pin to allow for ultra-low-power usage), and a reset button (great for restarting your program, or entering the bootloader)


Runs Arduino like a dream, and can be used for basic CircuitPython projects. For more advanced usage like datalogging or file storage, solder an SOIC SPI flash chip onto the bottom pads,


Same size, form-factor, and pin-out as Seeed Xiao

USB Type-C connector - If you have only Micro B cables, this adapter will come in handy!

ATSAMD21E18 32-bit Cortex M0+ - 48 MHz 32 bit processor with 256KB Flash and 32 KB RAM

Native USB supported by every OS - can be used in Arduino or CircuitPython as USB serial console, MIDI, Keyboard/Mouse HID, even a little disk drive for storing Python scripts.

Can be used with Arduino IDE or CircuitPython

Built in RGB NeoPixel LED

11 GPIO pins:

True analog output on one I/O pin - can be used to play 10-bit quality audio clips in Arduino (CircuitPython does not have storage for audio clips)

9 x 12-bit analog inputs (SDA/SCL do not have analog inputs)

1 x Optional AREF on A1

9 x PWM outputs (A0 is analog out, A1 is not PWM capable)

Hardware I2C port with STEMMA QT plug-n-play connector

Hardware UART

Hardware SPI

Hardware I2S

6 x Capacitive Touch with no additional components required

3.3V regulator with 600mA peak output

Optional SOIC-8 SPI Flash chip on bottom

Reset switch for starting your project code over or entering bootloader mode

Really really small
