Adafruit ItsyBitsy M4 Express featuring ATSAMD51

The Adafruit ItsyBitsy M4 Express features the Microchip ATSAMD51! Small, powerful, with a ultra fast ATSAMD51 Cortex M4 processor running at 120 MHz - this microcontroller board is perfect when you want something very compact, with a ton of horsepower and a bunch of pins. This Itsy is superfast, with it's 120MHz Cortex M4 with floating point support and 512KB Flash and 192KB RAM. Your code will zig and zag and zoom, and with a bunch of extra peripherals for support, this will for sure be your favorite new chipset. ItsyBitsy M4 Express is only is only 1.4" long by 0.7" wide, but has 6 power pins, 23 digital GPIO pins (7 of which can be analog in, 2 x 1 MSPS analog out DACs, and 18 x PWM out). It even comes with 2MB of SPI Flash built in, for data logging, file storage, or CircuitPython code. The most exciting part of the ItsyBitsy M4 is that while you can use it with the Arduino IDE, it ships with CircuitPython on board. When you plug it in, it will show up as a very small disk drive w
