Imp SD form factor


it’s been a long time since I was interested in the novelty of imp electric,

I have an imp version with the SD form factor,
does this version still exist, by which version is it replaced?


The imp001 was the only SD form factor; it is still a supported device.

It wasn’t directly replaced - ie there was no plastic-enclosed follow-up. Current imp types are imp003, imp004m, imp005 and imp006. If you’re looking for something “pluggable” then the imp006m2 reference design might be applicable?
