As well as announcing the availability of their new Crickit robot development board, Adafruit has also announced the availability of its new ItsyBitsy M4 Express featuring ATSAMD51. The new hardware is smaller than a Further but slightly larger than a Trinket offering hobbyists, makers and developers a small, powerful, microcontroller equipped with a ast ATSAMD51 Cortex M4 processor running at 120 MHz.
Adafruit explains a little more about the small form factor development board. “This Itsy is like a bullet train, 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.”
The ItsyBitsy M4 Express development board measures just 1.4 x 0.7 inches in size and as equipped with 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. The same chip is used on the Adafruit Metro M4 allowing you to quickly prototype your project on the larger Metro M4 or (the upcoming) Feather M4 and simply transfer it to the smaller form factor ItsyBitsy M4 Express when finished. The development board is also equipped with 2MB of SPI Flash built in, for data logging, file storage, or CircuitPython code.
