I am calling this THE SECRET DATA because i could find no explanation of the four terminals on the bottom of the board. I did find a forum where someone asked but the picaxe support person didn't answer that part of the question.
They are connected to ground.
Another thing worth knowing is that it as not compatible with the motor command in Logicator.(the flowchart programing gui)
I know most of you guys wouldn't use Logicator but i do and we are giving these things to beginners who need the heads up.
I also don't understand why a board designed for the picaxe-08M or M2 shipped with a picaxe-08. I think the extra input would be useful.
I am throwing together a quick bot to learn with so reports will follow.
