Feather is the new development board from Adafruit, and like it's
namesake it is thin, light, and lets you fly! We designed Feather to
be a new standard for portable microcontroller cores.
This is the Feather 32u4 Basic Proto, it has a bunch of prototyping
space built right in.
At the Feather 32u4's heart is at ATmega32u4 clocked at 8 MHz and at
3.3V logic, a chip setup we've had tons of experience with as it's the
same as the Flora. This chip has 32K of flash and 2K of RAM, with
built in USB so not only does it have a USB-to-Serial program & debug
capability built in with no need for an FTDI-like chip, it can also
act like a mouse, keyboard, USB MIDI device, etc. This chip is well
supported in the Arduino IDE and can run just about every
sensor/library out there.
To make it easy to use for portable projects, we added a connector for
any of our 3.7V Lithium polymer batteries and built in battery
charging. You don't need a battery, it will run just fine straight
from the micro USB connector. But, if you do have a battery, you can
take it on the go, then plug in the USB to recharge. The Feather will
automatically switch over to USB power when its available. We also
tied the battery thru a divider to an analog pin, so you can measure
and monitor the battery voltage to detect when you need a recharge.
Here's some handy specs!
* Measures 2.0" x 0.9" x 0.28" (51mm x 23mm x 8mm) without headers
* Light as a (large?) feather - 4.8 grams
* ATmega32u4 @ 8MHz with 3.3V logic/power
* 3.3V regulator with 500mA peak current output
* USB native support, comes with USB bootloader and serial port
* You also get tons of pins - 20 GPIO pins
* Hardware Serial, hardware I2C, hardware SPI support
* 8 x PWM pins
* 10 x analog inputs (one is used to measure the battery voltage)
* Built in 100mA lipoly charger with charging status indicator LED
* Pin #13 red LED for general purpose blinking
* Power/enable pin
* 4 mounting holes
* Reset button
The Feather 32u4 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!) … more
