Adafruit Feather 32u4 Bluefruit LE w/ Stacking Headers

Description

The Adafruit Feather 32u4 Bluefruit LE board provides a compact, all-in-one solution for developing Arduino-compatible projects requiring robust Bluetooth Low Energy (BLE) capabilities. At its core lies the ATmega32u4 microcontroller, operating at 8MHz with 3.3V logic, offering native USB support for direct programming and serial debugging without an external FTDI adapter. This design makes it ideal for portable applications where size, power efficiency, and integrated wireless communication are critical.

This Feather board is engineered to be a versatile platform for makers and developers, simplifying the integration of wireless features into their projects. The onboard BLE module enables seamless interaction with iOS, Android, Mac OS X, and Windows 8+ devices, making it perfect for creating applications that leverage smartphone or tablet connectivity. Furthermore, the inclusion of a built-in 100mA LiPo battery charger ensures your projects can be powered autonomously and recharged conveniently via USB.

The Feather 32u4 Bluefruit LE extends its utility with a rich set of I/O, including 20 GPIO pins, hardware serial, I2C, and SPI support, 8 PWM outputs, and 10 analog inputs. Its compact footprint and support for the Feather ecosystem allow for easy expansion using FeatherWings, making it adaptable to a wide range of embedded sensing, control, and IoT applications.
