Built for Arduino
By leveraging Arduino's tooling, troubleshooting the hardware is never difficult. You can start troubleshooting very quickly with a simple blink program to flash a LED. Or you can go as complex as programming your own firmware customizations.
Leverages the work of Leaders in the Maker Community
Adafruit has been making electronics easy and fun to learn for more than a decade. The Adafruit Feather nRF52832 was the first board that made BLE available to anyone who would want to build their own BLE devices, including keyboards.
Powered by Nordic's nRF52832 and nRF52840 System on Chip
The nRF52 chips are the most successful BLE SoC family in the Maker Community. The nRF52832 and nRF52840 are both powerful with an 32-bit ARM® Cortex™-M4 CPU running at 64 MHz. Both use the Nordic SoftDevices: Bluetooth protocol stacks that are pre-compiled binaries and BLE qualified when delivered, they are unaffected by the ‘develop and compile’ cycle of application development and always remain stable.
