It looks like there is a small delay on the MacroFab order. It was expected to start manufacturing on July 17th. However, as of July 21st the CircuitBrains Deluxe order is sitting at #40 in the queue. I’ve reached out to MacroFab support and asked for an updated start and ship date. I will provide another update when I get a response.
