OpenEVSE started in early 2011 with a simple experiment to try to generate the SAE J1772 pilot signal on an devolopment board. One experiment lead to another to another until a prototype J1772 compatible controller was born. With lots of feedback and interest from the great folks on the "My Nissan LEAF" Forum a few boards were offered to other hardware hackers. What started as a few boards (6 built in the first batch) turned into more and more... Today, OpenEVSE powers charging stations from many manufactures all over the world.
