QT Py! A new board from Adafruit! – CircuitPythonista Jepler requested that the QT Py have a spot for external flash chip on the bottom for expansion. Your wish is my command! Voila rev B, with a SOIC 8 on the bottom connected to a hardware SPI port. Not much else changed here, it is ready for another prototype revision and maybe a pretty silkscreen!
…and! here is the QT Py with lots of STEMMA QT devices: OLEDs and sensors – oh my! The QT Py is a SAMD21 board that can plug n play with any of our 50+ STEMMA QT boards, like this 128×128 OLED, PM2.5 Air Quality sensor, pressure/humidity/temp sensor and 9-DoF IMU. No soldering required, this is the easiest way to build electronics…coming soon to the adafruit shop! – video.
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 fire storage, solder an SOIC SPI flash chip onto the bottom pads:
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
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
USB Type C connector
Really really small
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
