    I agree.

    What about a right angle header in the crotch of it to breakout the SPI?

    What about making the surface touch capable? In other words, the whole surface acts like a pushbutton?

    Agreed. I have a few myself. I think that this has advantages over the proto-board for size, less soldering, and jamming stuff in to single holes.

    Rev2 should include a partial row of pins offset to support a header row for an Arduino. This will be really awesome.

    Use a generator and output the power to two motors, one for each track of a form of ATV.

    And therein lies the problem. I need adjustable LED brightness via adj. current or PWM at the above 12v and 1000mA and equally parallel across three LED.

    Three DC-DC converters require too much footprint. I can potentially use an off the shelf PWM LED driver for one LED with my 6S LiPo requirement. My hope is to do the current mirror.

    Is there another way to reliably run three LED’s in parallel without three separate DC-DC converters? Ultimately, if doing a current mirror as suggested above, if the first LED fails and no longer draws current, then the whole system fails, but I can live with that because i don’t kill all LEDs when one fails open because they are in true parallel.

    I need to prototype this… where is the time!

    Pete, For the comment by member # , I believe the intent of the comment about parallel LEDs was to use a constant current source on the first LED and use a current mirror on the second LED to ensure that an upset in the circuit doesn’t cause one LED to source current away from other parallel LEDs and burn out or if a LED fails, the other LEDs burn out from excess current. I was looking for something similar too. I was recently looking to drive three Cree MK-Rs in parrallel (each require 12.0v @ 1000mA for what I want to do) and I wanted to use a single DC-DC converter from a 6S hobby LiPo pack.

    Thanks, Frank
