this is cool, we were thrilled to see the open-source MicroPython derivative, CircuitPython on the SparkFun Pro nRF52840 Mini – Bluetooth Development Board – DEV-15025!

The board comes pre-programmed with a USB bootloader. You can develop programs for the nRF52840’s Cortex-M4 using either Arduino, Circuit Python, or C (using Nordic’s nRF5 SDK), and load that compiled code using a USB serial or mass-storage interface.

The Adafruit Feather nRF52840 will be shipping soon we’ve previewed it a few times on our weekly show(s) and Python on hardware newsletter (sign up!), we have some changes to the software and some final testing on the hardware we do first...
