Adafruit ItsyBitsy M0 Express

Adafruit ItsyBitsy M0 Express is a microcontroller board based on the Microchip Technology SAM D21 Arm® Cortex®-M0+ Microcontroller and offers multiple connectivity options. The M0 express microcontroller features a 32-bit processor running at 48MHz, six power pins, 23 digital GPIO pins, and a 2MB SPI flash chip. The built-in 2MB SPI flash chip can be used for file storage, data logging, and CircuitPython code storage. The M0 Express does not require compilers or installation as it can be used on any computer to build projects using Python programming. The ItsyBitsy M0 Express is ideal for driving NeoPixels or DotStars on any pins.
