Description
A small module from a Featherfamily,based on nRF52832system. Feather is designed for portable projects. Board has a small size (51 x 23 x 8 mm), can be powered by voltage from USB port or rechargeable battery3,7 V LiPol. The module has a Bluetooth LE system, providing wireless programming.
Mobile projects
Controller Feather is designed for mobile projects. Thanks to the integrated connector, it is possible to power it from the rechargeable LiPol battery 3.7 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.
Programming (Arduino IDE)
The module can be programmed using the Arduino IDE. For this, you will need to configure the software in a way provided by the manufacturer and connect the board using the microUSB cable. The settings of the Arduino IDE are available on the website of the manufacturer.
The module has twice more power than the previous nRF51system. Additional memory allows you to run operating systems of the real time (RTOS) to quickly create complex projects. It has professionally written Internet suites (BLE 5.0, OIC/OCF, etc.), development tools and professional functions of project management, for example, the protected bootloader that allows you to cryptographically sign the firmware and test them during the upgrade.
