{"title":"Adafruit ItsyBitsy M0 Express - for CircuitPython  Arduino IDE","handle":"adafruit-itsybitsy-m0-express-for-circuitpython-arduino-ide","url":"/products/adafruit-itsybitsy-m0-express-for-circuitpython-arduino-ide","description":"The Adafruit ItsyBitsy M0 Express is a compact yet powerful microcontroller board built on the ATSAMD21 Cortex M0+ running at 48 MHz. At just 1.4\" × 0.7\", it delivers the same capability as the Metro M0 or Feather M0 Express in a fraction of the size — perfect for shrinking prototypes into final builds.\n\nShips with CircuitPython pre-loaded — plug it in, edit the Python code on the drive that appears, and your project runs immediately. No IDE or compiler installation required. It also works with the Arduino IDE for C/C++ development.\n\nKey Features\n\n\nATSAMD21G18 Cortex M0+ – 48 MHz, 32-bit processor with 256 KB Flash and 32 KB RAM\n\n2 MB SPI Flash – Onboard storage for CircuitPython code, data logging, and files\n\nCircuitPython & Arduino – Ships with CircuitPython; also programmable via Arduino IDE\n\nNative USB – Serial console, HID keyboard/mouse, MIDI, or small disk drive\n\n23 GPIO Pins – 11× 12-bit analogue inputs, 1× true analogue output, 13× PWM, 7× capacitive touch\n\nVHigh Output Pin – Outputs higher of VBAT or VUSB; Pin 5 is level-shifted to high voltage\n\nDMA NeoPixel Support – Drive NeoPixels on the VHigh pin without processor overhead\n\nBuilt-in RGB DotStar LED – Plus a red Pin 13 LED for status indication\n\n3.3V Logic, 48 MHz – Hardware SPI, I2C, and serial\n\nAutomatic Power Switching – Runs from USB or battery with seamless switchover\n\n\nIdeal For\n\nCompact CircuitPython projects — no IDE installation needed\nShrinking Metro M0 or Feather M0 prototypes into tiny builds\nUSB HID devices, MIDI controllers, and data loggers\nNeoPixel and DotStar LED projects with DMA support\n\n\nPackage Contents\n\n1× Adafruit ItsyBitsy M0 Express (with CircuitPython pre-loaded)\n1× Header Strip (unsoldered)\n\n\nResources\n\nAdafruit ItsyBitsy M0 Express Guide\nCircuitPython.org\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":8231,"title":"Default Title","sku":"AF-3727","price":24.44,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
