We are very close to clearing out the backlog of LimeSDR orders. In particular, over the next ten days, we will be shipping the next batch of 1,000 boards to Crowd Supply's warehouse. This will be enough to fill all open LimeSDR orders and have plenty remaining for general availability. Thank you for your patience and support! We'll post another update once shipping to backers resumes.
