Once you have uploaded code, you can inspect and change variables (including functions) while your program is running. If you make something with an Espruino Pico and need to change it a year later, your original code is still there waiting for you!
This is the pinned version of the board, which fits perfectly into breadboard. If you need without pre-soldered pins, please visit Espruino Pico (unpinned).
