Adafruit Feather 32u4 Bluefruit LE MCU Development Board 2829

Feather is the new development board from Adafruit, and like its namesake, it is thin, light, and lets you fly! We designed Feather to be a new standard for portable microcontroller cores.

This is theAdafruit Feather 32u4 Bluefruit LE MCU Development Board 2829- our take on an all-in-one Arduino-compatible + Bluetooth Low Energy with built-in USB and battery charging. Its an Adafruit Feather 32u4 with a BTLE module, ready to rock!

Bluetooth Low Energy is the hottest new low-power, 2.4GHz spectrum wireless protocol. In particular, its the only wireless protocol that you can use with iOS without needing special certification and its supported by all modern smartphones. This makes it excellent for use in portable projects that will make use of an iOS or Android phone or tablet. It also is supported in Mac OS X and Windows 8+.

At the Feather 32u4s heart is at ATmega32u4 clocked at 8 MHz and at 3.3V logic, a chip setup weve had tons of experience with asits 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.

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 dont 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 analogue pin, so you can measure and monitor the battery voltage to detect when you need a recharge.

Its portable!
You have the option to use either a 3.7V Lithium polymer battery or connect to a PSU via micro USB. If you choose to power your board by battery, it makes it portable. So you can take it with you, wherever you need to. If you need to recharge it at any point, just plug it in via the micro USB and it will recharge.

TheFeather 32u4 Bluefruit LEuses the extra space left over to add our excellent Bluefruit BTLE module + two status indicator LEDs.
