Arduino Board - Serial Interface
This page has been updated for historical purposes and we cannot guarantee that the files will be available forever.
It's a basic board that uses RS232 as an interface to a computer for programming or communication. This board is easy to assemble even as a learning exercise. It has been designed to use the simplest component as possible so that it's easy to build even if you look for parts at the shop around the corner.
