This diminutive dev board comes with our favorite lil chip, the SAMD21 (as made famous in our GEMMA M0 and Trinket M0 boards).\u003c\/p\u003e\n\u003cp\u003eThis time it comes with our favourite connector - the STEMMA QT, a chainable I2C port that can be used with any of our STEMMA QT sensors and accessories.\u003c\/p\u003e\n\u003cp\u003eOLEDs! Inertial Measurement 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 you’re ready to load up some software and measure some light.\u003c\/p\u003e\n\u003cp\u003eUse any SparkFun Qwiic boards! Seeed Grove I2C boards will also work with this adapter cable.\u003c\/p\u003e\n\u003cp\u003ePinout 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 a controllable power pin to allow for ultra-low-power usage), and a reset button (great for restarting your program or entering the bootloader)\u003c\/p\u003e\n\u003cp\u003eRuns Arduino like a dream, and can be used for basic CircuitPython projects. For more advanced usage like data logging or file storage, solder an SOIC SPI flash chip onto the bottom pads,\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eLooking for a case to keep your Qt Py safe? \u003c\/span\u003eClick here to find it in our shop\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSame size, form factor, and pin-out as Seeed Xiao\u003c\/li\u003e\n\u003cli\u003e\nUSB Type C connector - If you have only Micro B cables, this adapter will come in handy!\n\u003c\/li\u003e\n\u003cli\u003eATSAMD21E18 32-bit Cortex M0+ - 48 MHz 32-bit processor with 256KB Flash and 32 KB RAM\u003c\/li\u003e\n\u003cli\u003eNative USB supported by every OS - can be used in Arduino or CircuitPython as a USB serial console, MIDI, Keyboard\/Mouse HID, and even a little disk drive for storing Python scripts.\u003c\/li\u003e\n\u003cli\u003eCan be used with Arduino IDE or CircuitPython\u003c\/li\u003e\n\u003cli\u003eBuilt-in RGB NeoPixel LED\u003c\/li\u003e\n\u003cli\u003e11 GPIO pins:\n\u003cul\u003e\n\u003cli\u003eTrue analogue 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)\u003c\/li\u003e\n\u003cli\u003e9 x 12-bit analogue inputs (SDA\/SCL do not have analogue inputs)\u003c\/li\u003e\n\u003cli\u003e1 x Optional AREF on A1\u003c\/li\u003e\n\u003cli\u003e9 x PWM outputs (A0 is analog out, A1 is not PWM capable)\u003c\/li\u003e\n\u003cli\u003eHardware I2C port with STEMMA QT plug-n-play connector\u003c\/li\u003e\n\u003cli\u003eHardware UART\u003c\/li\u003e\n\u003cli\u003eHardware SPI\u003c\/li\u003e\n\u003cli\u003eHardware I2S\u003c\/li\u003e\n\u003cli\u003e6 x Capacitive Touch with no additional components required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e3.3V regulator with 600mA peak output\n\u003c\/li\u003e\n\u003cli\u003eOptional SOIC-8 SPI Flash chip on bottom\n\u003c\/li\u003e\n\u003cli\u003eReset switch for starting your project code over or entering bootloader mode\u003c\/li\u003e\n\u003cli\u003eReally really small\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eRevision History\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAs of May 14th, 2024\u003c\/strong\u003e - this version now comes with nicer tactile buttons.
