Product Description

ADAFRUIT INDUSTRIES 2829 Feather 32u4 Bluefruit LE MCU Development Board is a thin, lightweight development board designed for prototyping Bluetooth Low Energy (BTLE) wireless applications on the 2.4 GHz band. It is powered by the ATmega32u4 microcontroller operating at 8 MHz with 3.3V logic, featuring 32K of FLASH memory and 2K RAM. The built-in USB-to-Serial programming and debugging capability allows easy development without additional converters.

The board integrates a Nordic nRF51822 Bluefruit LE module, providing versatile Bluetooth communication profiles suitable for data connections between devices or standard UART RX/TX operations. This makes it ideal for portable items controlled via smartphones or tablets running the Bluefruit app on iOS or Android.

Connectivity options include 10 analog inputs and 7 PWM output pins, enabling interfacing with sensors, actuators, and other peripherals. The compact size of 51 x 23 x 8 mm (excluding headers) and ultra-light weight of 5.7 grams allow for slim and portable designs.

Power flexibility includes operation from a 3.7V Lithium polymer battery or via microUSB for power supply and charging. The onboard 100mA LiPoly charger features a charging status indicator LED to monitor battery status.

This Feather 32u4 Bluefruit LE board is part of the Adafruit Feather family, which supports stackable accessories to expand capabilities. It is widely used in industrial prototyping, embedded system development, educational projects, and wireless sensor networks within electronics, automation, and IoT applications.
