Did you find a datasheet for it? That seems like a lot of pins for a serial connection.

Looks like it also support Ethernet – so that’s another 8 pins.

Nice. Gotta love the “Ralink Confidential” watermarks all over it. You better download that one before it disappears :wink:

I hope someone tries this out. I’m still sitting on a TI CC3000 that I haven’t had time yet to try and decipher.
