I’m trying to cram as much stuff on a 0.8x1.3" board that will send messages to 1-4 SURE 3208 displays. So far, I’ve got around 11x13mm available on the top to play with, seen in the upper left of the image below:
I need something that preferably takes no slow-clock input, minimal caps, etc.
Some of the items here might work:http://www.alibaba.com/member/kr1015760380/productlist.html but they’re minimum qty to order is 2000. I need one or two.
Then I found these from panasonic:http://www.digikey.com/scripts/DkSearch/dksus.dll?lang=en&keywords=P14961CT-ND&WT.z_slp_buy=Panasonic_Bluetooth&cur=USD They might work, but I need an external crystal, plus a 3v3 regulator and a few other parts, which I suppose I could put on the back side. Bluetooth 2.0 or 3.0 doesn’t matter so much as it will be using a minimum of receiving, but I can’t seem to find much else that is small enough, yet easy to use…even the LMX9838’s are 10x17 or so. Do any modules exist that fit these requirements and are easy to integrate?
EDIT: Actually the LMX9838 might work, but not sure how easy it is to use. Found this:
that doesn’t show an external crystal…so perhaps i can fit it in
