This schematic is provided AS-IS, with no support. We are releasing this schematic as an aid to advanced programmers who wish to re-purpose ("hack") their EZ-3micro PCB. Please note that as we are providing this schematic, we do no provide EZ-3micro code in any form (not even compiled). While we encourage hacking our circuit boards for your own needs, we ask that you proceed carefully to prevent "bricking" your EZ-3micro.
