Have recently jumped back into a bit of Imp development after a lengthy hiatus. (Alright, I’ll admit to a bit of hobbyist ESP8266/32 work over that time … but the Imp is just much more convenient for a couple of current projects).
I did a recent project using the 002 module (actually still have a few of those in the parts bin), but know that it’s time for me to switch to something more current. The 004 looks like the logical option, but alas, I can’t seem to find stock anywhere at my standard go-to sources (Digikey, Mouser, etc.). 003’s and 005’s seem fairly available … the 004, not so much.
So, I guess I’m just trying to understand the current status of the module … still active/recommended for new designs, a temporary casualty of the global chip shortage, when available again, etc.? I’ve done some previous layouts with the 003, so am not uncomfortable working with the 003 or 005 … just prefer to not have to go multilayer, mess around with antenna designs, etc. unless necessary.
Anyway, I’d just be interested in hearing the current story of the 004m before moving ahead.
