Regarding the JST PH connectors, I really wish SparkFun had chosen a connector with 2.54 mm pin spacing instead of the non-standard 2.00 mm pin spacing that makes it unnecessarily difficult to put connectors on breadboards or protoboards.
I am grateful to Seeedstudio for using similar connectors but with good ol' 2.54 mm spacing on their stuff… -
I like this board, and still ordered the NKC Electronics version due to prior comments here.
Have you considered a version with 5V to 3.3V power regulation and logic level conversion (preferably bidirectional for the three GPIO capable pins)? Something similar to the regulated Xbee BoB. -
One very old trick for getting an even heat distribution is to put a layer of clean dry sand at the bottom. I think about 1 cm (0.5") would be fine. The sand will spread the heat and you will get a “softer” and more evenly spread heat.
Since the sand will also retain or store heat you will not be able to accomplish any high speed changes in temperature, but I do not think that will be a problem. The sand is dry so there should not be anything to clean from the soldered boards unless some paste has found its way to the bottom side.
No public wish lists :(
