There are two Serpente boards, they are both virtually the same, except for the USB connector. The standard Serpente board contains a USB Type-C connector, and the Serpente Plug uses the board itself as a Type-A USB plug.
If you are familiar with the Digispark boards, you may notice some similarities. This fact is of course not incidental, the Serpente boards are inspired by the Digispark, both in form-factor as well as use-cases. The Serpente boards are meant to be used as quick and dirty, yet flexible, prototyping tools.
Here are some of the technical details regarding the boards:

This is the latest unstable release of CircuitPython that will work with the Serpente.
Unstable builds have the latest features but are more likely to have critical bugs.
Every time we commit new code to CircuitPython we automatically build binaries for it. They are stored on Amazon S3 by language (some which may be unreleased.) Try them if you want the absolute latest and are feeling risky.
All previous releases are available on GitHub. They are handy for testing but we recommend the latest stable otherwise.
