Description

Tiny form factor, USB Bluetooth module CSR4.0 (
Cambridge Silicon Radio, Inc.)
, new, open box, no drivers needed, tested with Windows 10.
Tested working on Windows 10, no extra drivers needed, connects to BT speakers, no other extensive testing performed.
It's a wee nubbin of a dongle, you will barely be able to see it once installed.  There is a tiny blue LED inside (sorry no photo - very elusive and difficult to photograph).
USB VID = 0A12 (Cambridge Silicon Radio, Inc.), PID = 0001, REV = 1915, if that helps at all.
For US shipping, you can choose between USPS First Class Package (cheaper) or USPS Priority Mail (faster and comes with up to 0 insurance for free). International buyers WILL have to pay more for shipping to your country, plus applicable taxes, customs, duties, etc. I have no control over how much this will be. If your country is not listed in the "Ships To:" section, then I will, unfortunately, be unable to ship it to you.
Also: YES! I will certainly combine shipping if you win more than one of my auctions within THREE (3) days. This saves me time and money, as well as saving you money. It's a win-win! Just leave me a note saying "Please HOLD to COMBINE shipping" and I'll take care of it.
