      Description
      Little Wire is multi-featured USB controlled open source hardware tool packed in a minimal form factor designed by ihsan Kehribar. Even though it has minimal form factor, and packed with full of features; there aren’t any SMT components involved, therefore it is very suitable for beginners to assemble. 
       
      This tool has to take instructions at run-time over USB. It can't work in a computer-less environment.
       
      Note
      V1.1 beta firmware released for the Little Wire. You can find the changelog and details from this link.
