Extending Our Campaign & Reducing Our Funding Goal

by Andrew Avtushenko

To our dear backers and subscribers,

Thank you to everyone who has supported uSDR and the WSDR platform so far. Over the past few weeks, we have been unable to post regular updates because we’ve been working hard on some pretty exciting new features that we’ll be revealing soon. Given that we still have a lot to say about uSDR, we have decided—in consultation with Crowd Supply—to extend our campaign until Thursday, August 17th, which gives us three additional weeks. We’ve also decided to reduce our funding goal to $40,000, as we are eager to receive and incorporate feedback about our platform. We’d also like to thank Crowd Supply, Lime Microsystems, and the AMD FPGA Playground for supporting this project.

The good news is that all crucial components are already in stock for all current orders, with plenty left over for additional units. Do hurry, though, as quantities will be limited!

Once again, thank you for your support. We can’t wait to hear your thoughts!
