Built on CircuitPython

By leveraging CircuitPython, 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.

Powered by Nordic's nRF52840 System on Chip

CircuitPython supports the most successful BLE SoC family in the Maker Community. The nRF52840 is powerful with an 32-bit ARM® Cortex™-M4 CPU running at 64 MHz. Uses 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.
