Have you alternative for this module?
its in stock isn’t it ? Shows as in stock when I look now !
Only in GHI and Mouser Shops, not in germany shop’s.
USB CLIENT SP module if you don’t want to use an external power supply.
Since you’re concerned about a specific reseller, your best approach is to contact them and get an ETA on the new supply. The GHI team have only had stock for a week or so, which has probably affected Watterot too, so I would expect they should be getting some more very soon, but they probably have the best idea on when that might be.
As Mike said, the alternative is the SP module but that is only USB powered. I used mine with a 5v power supply that I had spliced a USB cable onto the end of.
