Recently we had a problem with our scheduled fabrication run of Watchmon1 supervisor as all were rejected, unfortunately for 2 different reasons:
What we had not anticipated was the global shortage of MK20DX256VLH7 from Freescale semiconductor. The Teensy 3.2 has the same processor and there is a 26 week lead time. Our recent manufacturing run had 2 different batches supplied as components for the processor, one worked, the other was very old stock from 2012 that was listed as faulty by Freescale. We did not learn about this shortage until after they arrived at our office.

This means we are back and able to supply limited quantities whilst we wait from the new Watchmon4. The first fabrication is almost complete with the likely transport delays over xmas, the WatchMon4 is on track for sale from the end of late January 2018.
