Alpha Testing Program and Extended Campaign Pricing

First, thanks to everyone who has supported us so far. We're in the final week of the campaign and over three quarters the way to our funding goal! We're well within reach of the goal, but we'll need your help. The funding goal wasn't arbitrary - if we don't reach it, then the project will be put on hold, none of your credit cards will be charged, and no one will get a LimeSDR. Community-driven free and open source hardware projects rely on individuals' support to get off the ground. LimeSDR is no different. If you haven't yet pledged for a LimeSDR, please do! if you have, please help spread the word far and wide to everyone you know, be it by social media, email, in-person, or carrier pigeon.

Introducing the Driver Architecture

Having a great hardware platform is one thing, but as any experienced engineer will tell you, this is only half of the story and you also need solid software support to realise the true potential of that hardware. So it's hardly surprising that we've had quite a few backers asking for more details of the driver software for LimeSDR and whether it will support this application or that application.
