The Serpente R2 from Solder Party is yet another addition to the now long roster of compact Atmel microcontroller-based breakout boards aimed at the maker community.

Compact is the word: the R2 is just 24 x 22mm in size yet makes room for 4MB of Flash, a reset switch, GPIO breakout, three-colour RGB LED and — perhaps the best bit — an integrated USB-to-UART adaptor.

The R2 I have here has a female USB-C connector but you can also get R2s with either a male USB-C port or an extended circuitboard that has four USB lines: both can be slotted straight into the right kind of port on your computer. That doesn’t mean the R2 is intended as a GPIO and bus breakout for a host computer. No, it’s the board’s way of making itself easy to transfer code to.

Connect the R2 up and a CIRCUITPY drive mounts on your system. Open it up and copy code across to start using the device. Simple.
