Adafruit Feather M0 Basic Proto - ATSAMD21 Cortex M0

Feather M0 Basic Proto is a compact development board that thrives on simplicity and power. Built on the ATSAMD21G18 ARM Cortex M0 processor, it offers a 48 MHz clock speed and 3.3V logic, ensuring robust performance. It matches the strength of the Arduino Zero with 256KB of FLASH memory and 32KB of RAM, catering to expansive project needs.

Designed with portability in mind, Feather M0 includes a built-in USB for program and debugging, eliminating the need for additional components. It supports 3.7V Lithium polymer batteries with inbuilt charging, seamlessly switching between USB and battery power, complete with battery voltage monitoring for timely rechargers.

Measuring a mere 2.0" x 0.9" x 0.28" and weighing 4.6 grams, it is compact yet feature-packed. It boasts 20 GPIO pins with hardware Serial, I2C, and SPI support, PWM outputs on all pins, six 12-bit analog inputs, and one 10-bit DAC output. A tiny prototyping area is perfect for bypassing a breadboard for small add-ons.

With a USB bootloader pre-installed, it integrates seamlessly with the Arduino IDE. The package includes headers for easy soldering and breadboard integration, though the Lipoly battery and USB cable are sold separately. Feather M0 Basic Proto is perfect for various applications, bringing dreams to life with its versatile functionality.
