QT Py
- 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
- 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 AP2112
- Optional SOIC-8 SPI Flash chip on bottom
- Reset switch for starting your project code over or entering bootloader mode
- USB Type C connector
- Really really small
CircuitPython
- QT Py Haxpress used with 2MB Flash EEPROM
- blink.py for QT Py
Flash EEPROM 2 MB
