I just added a little note to the Third stage test instructions for the UCB, to deal with the issue that tests 3 to 6 are for StepperController boards not for raw UCBs. It reads:
> Please Note: The tests that follow are specific to Stepper

It would be better to remove tests 3 to 6 from the UCB page and add them to the Stepper Controller page, and to more fully document use of poke... but at least this is a start.
