Description

A small module with a microcontroller AVR Atmega 32u4. Feather is designed for portable projects. Thanks to the microUSB connector and uploaded bootloader, the module can be programmed directly fromthe Arduino IDE environment. Board has a small size (51 x 23 x 8 mm) can be powered by voltage from USB port or from rechargeable Li-Pol battery3,7 V Li-Pol. The module has built-in Bluetooth 4.1 BLE, so it can become the wireless control center.

Mobile projects

Controller Feather is designed for mobile projects. Thanks to the integrated connector, it is possible to power it from the rechargeable Li-Pol battery3.7 V. The battery voltage was led through an analog pin, so you can constantly monitor the state of charge of the lipol. Also available is powering from the microUSB port.
