Product Description
"The Adafruit Feather are a complete line of development boards from Adafruit that are both standalone and stackable.
They're able to be powered by lipo batteries for on-the-go use or by their micro-USB plugs for stationary projects.
Feathers are flexible, portable, and as light as their namesake.
At the Feather M0's heart is an ATSAMD21G18 ARM Cortex M0 processor, clocked at 48 MHz and at 3.
3V logic.
This chip has a whopping 256K of FLASH (8x more than the Atmega328 or 32u4) and 32K of RAM (16x as much)! This chip comes with built in USB so it has USB-to-Serial program & debug capability built in with no need for an FTDI-like chip.
ATSAMD21G18 @ 48 MHz with 3.3 V logic/power 256 KB of FLASH + 32 KB of RAM No EEPROM 32.768 KHz crystal for clock generation & RTC 3.3 V regulator with 500 mA peak current output USB native support, comes with USB bootloader and serial port debugging 20x GPIO Hardware Serial, hardware I2C, hardware SPI support PWM outputs on all pins 6x 12-bit analog inputs 1x 10-bit analog ouput (DAC) Built in 100 mA lipoly charger with charging status indicator LED red LED for general purpose blinking 4 mounting holes Reset button Dimension: 51 x 23 x 8mm The Feather M0 Basic Proto has some extra space left over, so we give you a tiny little prototyping area.
If you just need to attach a button or sensor, you may be able to skip out on a breadboard and wire it directly on there.
Comes fully assembled and tested, with a USB bootloader that lets you quickly use it with the Arduino IDE.
We also toss in some header so you can solder it in and plug into a solderless breadboard.
Lipoly battery and USB cable not included (but we do have lots of options in the shop if you'd like!)"
