This little board has an STM32 microcontroller pre-programmed with Espruino all ready to go so you can start playing immediately. Warning: if you only use Assembly and think that even embedded C/C++ is for wimps, this device might explody your head.
Note: As of Friday, October 2nd, 2015 we are selling the updated Pico with both a more helpful silkscreen marking for power, an updated USB power diode, and a 500mA polyfuse added!
The Pico is also designed to be easy to include in your own designs and builds. The .01” pins are easy to fit in to sockets, and castellated edges mean that unpinned Picos can easily be surface-mounted directly to a PCB. And to make it even easier, Espruino provided a part library for Eagle CAD that includes the Pico’s footprint in several different configurations.
The Espruino Pico’s fast response time has a lot of advantages. It allows for quick and easy debugging and is a great way to test your project before your big reveal. In addition, you can control the Espruino from almost anything - Windows, Mac OS, Linux, RasPi, Android, anything that can talk to a USB Serial port.

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.
