      It was brilliant

      My husband loves these tiny series and we both are really impressed! We’d love to collect these!

      Amazing tech with a huge potential

      Amazing all-in-one gadget package based on ubiquitous RP2040 with great support all across the technology field.
      Much more than a toy, a real platform based on open standards, already supporting Python and C++. Let's add Rust to the mix and a larger, more usable ThumbyXL version, to let this technology skyrocket.


      This is amazing! And WOW, it's even smaller than I expected! The build is solid, and the resolution? Oh my gosh. Amazing! I bought two for my brother but of course I forgot the link cable so I'll be sure to order that soon! Well done, TinyCircuits ^U^
