The SingleWireSerial board is being designed to fix a very simple problem: running out of pins while building large and complicated projects. Because most major projects are already being built by the time pins become an issue, the SWS board is designed to be used as if it were a natural extension of the Arduino itself. With this in mind, we took extra care to design the SWS board so that it could be added to any project on the fly without having to change anything. This expansion module is being designed by and for people with big and exciting ideas who don't want to get caught up on the little things. If you are interested in using a SWS board in one of your own projects, please consider backing our Kickstarter. We have built several functional prototypes and are currently in the process of turning the design into a printed circuit board to be distributed to backers before the end of 2017. Once the PCB is developed, we will make all documentation (schematics, eagle files, etc. public so that other hobbyists can learn from it. Thank you! ​

Using the SingleWireSerial is a matter of four simple steps:
