You're right, for the 1K pullups/pulldowns, it is a bit to strong, I would recommend 4K7 or 10K.

1K pullups and pulldowns are a power hog too!

How so? If those pins aren't used as outputs, then there's no serious current being pulled through those resistors except for when a pushbutton is hit.

when shopping on my favorite store, i found a new module: the 12F

http://world.taobao.com/item/521945102409.htm?spm=a312a.7700714.0.0.8C26Cc#detail

it should have improved stability, better antenna, 4 layer pcb.
i couldn't find any documentation but when its available i will post it here. when the new units arrive i will post the decap photo's here.

cheers.

Unless it wasn't already there 4 days ago, then you must not have looked very hard because it's stated right in the product description... Now of course it is in chinese but I've translated it using google, so do expect some errors, though it's not a plain copy/paste, I did properly copy the tables, images, etc.. to make it easier to read.
I've linked it as a .docx attachment or you can view it on google docs here.

Hey Kurt, thanks for supplying the info + translation
