The Circuit Python board will draw its power from the Android device, so keep that in mind before you program some crazy light show.

This discovery led to further digging, of course. With some hacking, the TI-Python can instead be replaced with other boards based on Atmel SAMD21 chips.

At the writing of this article nearly 30 different boards currently support CircuitPython, with 28 boards now available in two more but will be shipping very soon.
