We designed Feather to be a new standard for portable microcontroller cores.\u003c\/p\u003e\n\u003cp\u003eThis is the \u003cstrong\u003eAdafruit Feather 32u4 Bluefruit with Headers\u003c\/strong\u003e - 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! We have other boards in the Feather family, check'em out here. For the Feather 32u4 without pre-soldered headers, check out this link.\u003c\/p\u003e\n\u003cp\u003eBluetooth 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 it's supported by all modern smart phones. 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+.\u003c\/p\u003e\n\u003cp\u003eAt 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 \u0026amp; debug capability built in with no need for an FTDI-like chip, it can also act like a mouse, keyboard, USB MIDI device, etc.\u003c\/p\u003e\n\u003cp\u003eTo 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHere's some handy specs!

For most people, they'll be very happy to use the standard Nordic UART RX\/TX connection profile. In this profile, the Bluefruit acts as a data pipe, that can 'transparently' transmit back and forth from your iOS or Android device. You can use our iOS App or Android App, or write your own to communicate with the UART service.\u003c\/p\u003e\n\u003cp\u003eThe board is capable of much more than just sending strings over the air! Thanks to an easy to learn AT command set, you have full control over how the device behaves, including the ability to define and manipulate your own GATT Services and Characteristics, or change the way that the device advertises itself for other Bluetooth Low Energy devices to see. You can also use the AT commands to query the die temperature, check the battery voltage, and more, check the connection RSSI or MAC address, and tons more. Really, way too long to list here!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUse the Bluefruit App to get your project started\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eUsing our Bluefruit iOS App or Android App, you can quickly get your project prototyped by using your iOS or Android phone\/tablet as a controller. We have a color picker, quaternion\/accelerometer\/gyro\/magnetometer or location (GPS), and an 8-button control game pad. This data can be read over BLE and piped into the ATmega32u4 chip for processing \u0026amp; control\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eYou can do a lot more too!\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\nThe Bluefruit can also act like an HID Keyboard (for devices that support BLE HID)\u003c\/li\u003e\n\u003cli\u003e\nCan become a BLE Heart Rate Monitor (a standard profile for BLE) - you just need to add the pulse-detection circuitry\u003c\/li\u003e\n\u003cli\u003e\nBuilt in over-the-air bootloading capability so we can keep you updated with the hottest new firmware. Use any Android or iOS device to get updates and install them. This will update the native code on the BLE module, to add new wireless capabilities, not program the ATmega chip.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eComes fully assembled and tested, with a USB bootloader that lets you quickly use it with the Arduino IDE. Also comes with \u003cstrong\u003eheaders pre-soldered\u003c\/strong\u003e, so you can plug right into a solderless breadboard.
