Product description: ItsyBitsy M4 Express ATSAMD51 microcontroller board - Adafruit 3800
A small board with a powerful ATSAMD51 microcontroller with Cortex M4 processor, running at 120 MHz and equipped with 512 kB of Flash memory and 192 kB of RAM. The ItsyBitsy M4 Express has 23 digital GPIO (digital input/output) pins, including: 7 analog pins (inputs), 2 analog DAC outputs, and 18 PWM channels. There is also a microUSB port, battery connector, and reset button on the board.
The ItsyBitsy M4 can be used with the Arduino IDE, but the manufacturer ships it with CircuitPython by default. When the board is plugged in, a small disk appears with a main.py file to edit. It requires no installation, IDE environment or compiler. It can be used on any computer: on ChromeBooks or machines where you can't install software.
ItsyBitsy M4 Express ATSAMD51 microcontroller board - Adafruit 3800.
