Let me start with a link to wikipedia: https://en.wikipedia.org/wiki/ESP8266
Just checked: what I have been working with are "nodemcu with LUA" (this one without a fancy version information), "ESP-12F" and some others I'll have to resurface in one of my archives.
My first search was on ebay - location worldwide, sort price ascending.
If you search for "ESP 8266" resp. "nodemcu" resp. "ESP-12F" (each without the quotes), a lot of sellers is expected to surface. Best to have a module with integrated USB interface: the better ones won't require you to depress a key to start downloading.
PLUS: assuming that your console might be something similar to the console of your heating/cooling device: you can easily service the touch, display, buttons etc. with the ESP. No need for a separate PIC and controller-controller communications on this side (provided the number of pins on the ESP module suffices).
Dug up another "nodeMCU V3", cannot locate my ESP-based WiFi scanner.
Just checked aliexpress: they offer a lot of ESP8266 modules, starting at around 2 $ incl. shipping.
Just enter "nodemcu", sift through the offers and select the module of your choice.
(Couldn't find an EMW3060 there. Seems, this one is mainly offered by seeedstudio.)
Most ESP modules use the CH340/CH341 USB converter. This one is (was?) not supported by current Win versions. But it's not too difficult to download and install the corresponding driver.
