I've received an updates on the boards. Long story short, there have been some delays as David Pitts has been extra busy moving house.
I would expect orders without Smart Receivers to ship late May.
The current status:
F48's are in Australia so I should get them soon to start testing
F16v3's and expansion boards should be here in 2-3 weeks
Smart Receiver ETA is not yet confirmed.
The complexity with the Smart Receivers is that the software is programmed by the CPU manufacturer rather than via me and so the software must be completed before they can be manufactured.
I do have about 35-40 regular receivers here, so if anyone has ordered F48 + Smart Receivers and wants to swap to regular receivers to get their order sooner, please let me know. Available on a first in first served basis for orders with smaller numbers of receivers.
Meanwhile I've been getting prepared for the shipments:
