AR9271 chipset is the only one with Open Source Firmware and Linux drivers. It has build in Kernel support since Kernel 2.6.35 so if you want to run GNU/Linux clean of non-free binary blobs with unknown content this is the device for you. It will work with your desktop PC, laptop, or SBC like OLinuXino and Raspberry Pi etc.
MOD-WIFI-AR9271-ANT samples are tested and proven to work with all our OLinuXinos and have excellent WiFi reception due to the huge antenna they came with. We have pending order and they will be in stock very soon.

Say Free Software not open source !

Nice! AR9271 is noteworthy for:
1) Superb sensitivity. 9271 is good on its own, and antennae makes it even better.
2) Good software support, at least in Linux it works very well.
3) In Linux it supports virtually all imaginable interface modes. One can even create access point using this thing, though subject to some limits. Wanna packet injection for pentesting? Here you go. Wanna to play with meshes? Ok, here it comes. Want to try out wi-fi Direct aka p2p-mode? Ok, it supported.
4) Open and clean design. No nasty surprises. There is datasheet on 9271 floating around, firmware is open, and actually fairly simple. No BS.
Recently Juniper has been caught on universal master password inserted into their routing devices. Another proprietary bitch caught. And huge number of Juniper crap has been already pwned, attacks are at full swing right NOW. And so, someone still asking why we’re not fond of their blobs? Because we do not want our systems to get suddenly compromised by hackers, NSA or whoever else learns how to use backdoor.

p.s. and just 9 EUR? Whoa. that’s a DEAL! Buying adapter with known IC, well supported by Linux, at affordable price? People often asking me where to get good wi-fi adapters supported by Linux. Now I know the answer.
p.p.s: hmm, what about some affordable SDRs with “right” ICs? Uhm, I mean RTLSDR things of course. These are wonderful masterpieces for those who does not gives a fuck about boring DVB-T crap and rather in mood to get idea about digital signal processing, radios around, and so on. Of course one can plug one of these to oLinuXino, etc – making their uber-custom experimental/research RF receiver design fairly small 🙂
Have a good holidays, Olimex! 🙂

do you know if this version has tx and rx pins accessible on the pcb? see the wiki they make a difference there.
