Adafruit Feather 32u4 Bluefruit LE with Headers - Assembled

Feather 32u4 Bluefruit with Headers from Adafruit is designed for easy integration in portable microcontroller projects. Combining an Arduino-compatible core with Bluetooth Low Energy (BLE) capabilities, this board offers both USB and battery power options.

At its core, the ATmega32u4 operates at 8MHz and 3.3V logic, providing 32K of flash and 2K of RAM. With built-in USB functionality, it supports programming and debugging without additional components.

The integrated Bluefruit LE module, based on the Nordic nRF51822 chipset, facilitates seamless communication with iOS and Android devices. Use the Bluefruit Apps for quick prototyping, or customize device interactions through the comprehensive AT command set.

Features include 20 GPIO pins, 7 PWM, and 10 analog inputs, along with hardware support for Serial, I2C, and SPI. The board is equipped with a 100mA LiPoly charger, voltage monitoring, and automatic power switching between USB and battery power.

Measuring just 2.0" x 0.9" x 0.28" at 5.7 grams, this board is as light as its name suggests. Pre-soldered headers make it simple to connect directly to solderless breadboards for fast development.
