The folks at SparkFun were startled by how small USB bluetooth adapters had become so they split one open. They noted a few interesting design features. It has a small folded trace antenna on the board edge. Now we wonder what those tiny Buffalo drives look like inside. The only bad part about these bluetooth devices is that the led tends to be green instead of blue, and is placed on the underside of the board, so if you are using it on a laptop, it makes it impossible to see the light.
Also, white versions cost like 20 times more. The regular black version can be had for like 2. I have one of those. Bought it for like 3 bucks with free shipping and works on my Desktop as well as my iBook. They got the part number wrong. If you zoom in on the picture that is on the sparkfun website, it says aqa not asqa. The also use too many passive components. Exicting stuff! Really amazing how tightly packed everything is.
Reassembled, and works great. Insane how things can shrink down. Actually, the reason kinks are often avoided is because they tend to generate rf as a result.
Looks like this one needs some help from a dremel to cut the USB plug a little shorter and to cut the sides off that huge handle…. I have the 2. I cracked one of these open about a month ago.
I like to see more cracked devices than arduinos. It isnt really dificult to open them, just some pressure and crack!

The device works well on bit versions of BSD and Linux. The exposed usb plug in the pic reminds me of the iron man mask…. After letting it dry thoroughly it still works ok.
Looks like this one needs some help from a dremel to cut the USB plug a little shorter and to cut the sides off that huge handle… My bluetooth adapters are smaller than this one.
My lab bought a few of these. Keep in mind that they often all have the same bluetooth id. Leave a Reply Cancel reply. Search Search for:.
