that's a very tempting option indeed, if compatible. I'm having no issues with Wifi, but the ESP32 V3 is very attractive (no more PSRAM issues…).
I have an arduino project that polls buttons and can send ir codes, update mqtt, and post json to a rest api https server. It also has mono and color displays. It uses the "comet protocol" to keep the data on the display current so it always has a http transaction open. I was having trouble with random hangs and upgrading to esp32-devkit V3 modules has almost completely eliminated this problem.
I don't have the equipment to desolder the module though… or any experience with that.
I have a little! I got a quick 861DW and successfully swapped a SIM7600A onto a ovms modem board. That is, I can talk to it but haven't done any work on adding support for it. (Like many of us, I have way too many projects in progress...) I also swapped a CP2102 (tiny little bugger). Something I wasn't expecting is that the quick is an excellent tool for heating heat shrink! Gone are the days of using a lighter (and leaving charcoal marks on the tubing). I think swapping the wroom module will actually be easier than the simcom, it has fewer pins. On the other hand it looks like I would have to remove one or both of the sma jacks and I know from experience that is not easy, they have a lot of thermal mass. I think I'll order a module and see if I can manage to remove the module with them in place, hopefully I can hold them out of the way (and protect the cables from heat, I have plenty of kynar tape).
