I will probably get out the perfboard and hand-wire an interposer that lets me use one of the esp32 development boards i have here, since it is so much faster than the 8266. I did find an aliexpress seller that sells the v0.9 carrier board with no esp8266 module and the usb interface and voltage regulator, so in theory you wouldn't have to desolder the original esp module from your oldschool nodemcu to put a 4MB esp12f on it.

You can still get those but they probably have a 512KB version of the esp12 module on them that can't support esp3d. It fits the v0.9 nodemcu board from 2014. Imagine my disappointment when, v3 extension in hand, i discover that the headers don't match any of the, what, 5 different nodemcu style development boards i have. With the maturation of the ESP3D project I thought it would be pretty neat to have a neat and tidy way to mount an ESP8266 module or better yet ESP32 module to my RADDS. Much cheaper than a duet and extension for the duet anyway.
ESP8266 DIPTRACE DRIVERS
A radds plus the v3 extension board also appears to be one of the cheapest ways to have 9 stepper drivers if you are doing something like Z leveling with 3 z steppers and 4 extruders. But it seems like there are a lot of them out there, firmware support is only improving, and for many there aren't compelling reasons to upgrade from them.
