Adafruit Feather 32u4 Bluefruit LE with Stacking Headers - Assembled

The Adafruit Feather 32u4 Bluefruit LE is an all-in-one, Arduino-compatible development board featuring Bluetooth Low Energy (BLE) connectivity. It comes assembled with Feather stacking headers, USB native support, and built-in battery charging for a 3.7V Lithium polymer battery, making it perfect for portable and wireless projects.

Featuring an ATmega32u4 microcontroller clocked at 8 MHz with 3.3V logic, this board includes 32KB flash, 2KB RAM, USB bootloader, and debugging capabilities without the need for additional FTDI chips. The embedded Bluefruit LE module (nRF51822) enables easy Bluetooth data transfer with iOS, Android, Mac OS X, and Windows 8+ devices.

Key Features:

• ATmega32u4 @ 8MHz with 3.3V logic
• Bluetooth LE nRF51822 module for wireless connectivity
• Built-in 100mA LiPo battery charger with status LED
• USB native support with bootloader and serial debugging
• 20 GPIO pins, including 8 PWM and 10 analog inputs
• Stacking headers pre-soldered for easy FeatherWing compatibility
• Includes power/enable pin, reset button, and 4 mounting holes
• Dimensions: 51.2mm x 22.8mm x 19.2mm; Weight: 8.5g

Bluetooth LE Capabilities: Use the Bluefruit app for iOS and Android as a controller with features like color picker, sensor data, and gamepad controls. The Bluefruit module supports AT commands to control behavior, read battery voltage, query MAC address, and more. It can function as an HID keyboard, heart rate monitor, or UriBeacon. Over-the-air firmware updates are supported using Android or iOS devices.

The Feather 32u4 Bluefruit LE board is ideal for wireless, portable, and IoT projects. Battery and MicroUSB cable are not included but available separately.
