Adafruit Feather M0 Basic Proto - ATSAMD21 Cortex M0

The Feather M0 Basic Proto is a compact and versatile development board from Adafruit, designed for portable microcontroller projects. Thin, lightweight, and packed with features, this board sets a new standard for portable development platforms. The Feather M0 is perfect for those looking to create small, battery-powered projects.

Key Features:

• Microcontroller: At its core is the ATSAMD21G18 ARM Cortex M0 processor, running at 48 MHz with 3.3V logic. It’s the same chip used in the Arduino Zero.
• Memory: The board offers a generous 256KB of FLASH and 32KB of RAM, giving you plenty of space for your projects.
• USB Native Support: Built-in USB-to-Serial capabilities mean no need for a separate FTDI chip, allowing easy program and debug capabilities.
• Battery-Friendly: A connector for 3.7V Lithium Polymer batteries comes standard, along with a built-in battery charger. When plugged in via USB, it automatically switches to USB power. You can monitor battery voltage via an analog pin to check when a recharge is needed.
• Prototyping Area: The Feather M0 includes a small protoboard space, making it easy to directly attach components without the need for a breadboard.

Specifications:

• Size: 2.0" x 0.9" x 0.28" (51mm x 23mm x 8mm) without headers
• Weight: 4.6 grams
• Processor: ATSAMD21G18 @ 48MHz, 3.3V logic
• Memory: 256KB of FLASH, 32KB of RAM
• Power: 3.3V regulator with 500mA peak current output
• GPIO: 20 pins, including hardware Serial, I2C, SPI, and PWM outputs on all pins
• Analog: 6 x 12-bit analog inputs, 1 x 10-bit analog output (DAC)
• Charging: Built-in 100mA LiPo charger with charging status LED
• Mounting Holes: 4 holes for easy mounting
• Reset Button: For quick restarts

Extras:

• USB Bootloader: Allows you to quickly upload code through the Arduino IDE.
• Pin #13 LED: A red LED for simple general-purpose blinking.
• Prototyping Area: Add your own components directly without needing a breadboard.

This board comes fully assembled and tested, ready to get started with your projects. It also includes some header pins so you can solder them and plug the board into a solderless breadboard. Please note: LiPo battery and USB cable are not included, but we offer them in our shop.

Perfect for portable and wearable projects, the Feather M0 Basic Proto combines ease of use, portability, and a wealth of features to help bring your ideas to life.
