With a native USB and a built-in regulator, FeatherSnow comes with a UF2 bootloader and a small CircuitPython runtime. The SWD header is populated. FeatherSnow works with CircuitPython or Arduino.

For skilled makers, you could order a kit to build everything and flash the UF2 bootloader and CircuitPython yourself. All the open-source code is maintained by AdaFruit.
