Questions

Is there a KiCad symbol and footprint for the ESP-12F?

Yes. The symbol is RF_Module:ESP-12F and the footprint RF_Module:ESP-12E, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ESP-12F?

SMD,24x16mm, with 22 pins. Its footprint is drawn on this page.

Where is the ESP-12F datasheet?

DOIT publishes it: the Datasheet link on this page opens it.

Where can I order the ESP-12F?

JLCPCB lists it as part C19949064, with 2,314 in stock; the sellers' links on this page open their listings.

What can replace the ESP-12F?

Parts like it in the library: the ESP-12F(ESP8266MOD) by Ai-Thinker, the ESP-12E by Ai-Thinker, the ESP32-WROOM-32E-N4 by Espressif Systems and the ESP32-WROOM-32 by Espressif Systems. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the ESP-12F?

292 boards in 216 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
