Adafruit Feather nRF52 Bluefruit LE - nRF52832

The Adafruit Feather nRF52 Bluefruit is a versatile, all-in-one Bluetooth Low Energy (BLE) board that combines a native Bluetooth chip, the nRF52832, with built-in USB support and battery charging. Designed for ease of use, it’s ideal for portable, low-power projects that require wireless communication, such as wearable devices, IoT, and wireless sensors. The Feather nRF52 simplifies your development process by eliminating the need for a separate microcontroller; the nRF52832 is fully programmable using the Arduino IDE, providing high performance and low power consumption in one compact package.

Key Features:

• ARM Cortex M4F Processor: Running at 64 MHz with hardware floating point acceleration for faster computation.
• Memory: 512KB flash memory and 64KB SRAM for plenty of space to store your code and data.
• Bluetooth Low Energy (BLE): 2.4GHz radio compatible with Bluetooth Low Energy devices, including iOS, Android, Mac OS X, and Windows 8+.
• Arduino IDE Support: Program directly via USB, with no need for an external chip.
• Power Efficiency: Operates from 1.7V to 3.3V with internal voltage regulators and built-in battery charging, allowing for portable battery-powered applications.
• Wireless Range: Up to +4dBm output power, allowing reliable communication over a longer distance.
• GPIO & Peripherals: Includes 19 GPIO pins, 8 x 12-bit ADC pins, up to 12 PWM outputs, and more for flexible interfacing with sensors and actuators.
• Size: Measures 2.0" x 0.9" x 0.28" (51mm x 23mm x 8mm) and weighs only 5.7 grams, making it light and compact.
• Built-in Features: A reset button, 4 mounting holes, and an optional SWD connector for advanced debugging.

Ideal For:

• Bluetooth Low Energy (BLE) Projects: Compatible with BLE profiles like UART, HID Keyboard, Heart Rate Monitor, Beacon, and more.
• Mobile Connectivity: Easily integrate with iOS and Android devices using the free Bluefruit App, or create custom apps for specific Bluetooth communication.
• Portability: Add a 3.7V LiPo battery to make your project truly portable. The Feather will automatically switch between USB and battery power when necessary.
• Wireless Data: Create projects that wirelessly transmit data from your microcontroller to your smartphone or tablet.

Additional Features:

• Bluefruit App Integration: Quickly prototype your BLE projects using the Bluefruit iOS or Android App, which supports features like a color picker, gamepad, and sensor data transfer.
• Over-the-Air (OTA) Updates: The Bluefruit module supports over-the-air bootloading, allowing you to update your firmware via Bluetooth without needing a USB connection.
• Expandable with FeatherWings: Compatible with other Feather boards and FeatherWings for even more functionality.

This fully assembled and tested Feather board comes with a USB bootloader for quick programming in the Arduino IDE, along with a small piece of header to solder for breadboard or perfboard use. Note: Lipoly battery and MicroUSB cable are sold separately.

Whether you’re building a smart wearable, IoT device, or custom Bluetooth controller, the Adafruit Feather nRF52 Bluefruit gives you the flexibility, performance, and wireless connectivity you need to bring your project to life.
