NodeMCU ESP-12F and Arduino

I have tried to use Arduino to talk to my NodeMCU ESP-12F board. I see that the board selection goes only to 12E. Is there any way to make a 12F talk to the Arduino IDE?

12E and 12F are identical in programming point of view.
If I recall, the only difference is the PCB antenna design.

I can try and pick that board. I did use the generic ESP8266 board and I got lucky in that it eventually talked to my board. The USB kept disconnecting/connecting which made it quite flaky.

Also on generic it seems to limit itself to 1M when I have 4M on my board. THere are two 4M settings 1 SPIFFS and 3 SPIFFS. What is a SPIFFS?

neither setting made a difference

Generic has also 4M options, if yours don't maybe the version is too old. check boards.txt file, 4M options are there.
SPIFFS is a limited file system emulated in the free flash space, it allow to read/write files.
I've mentioned "limited" because there is no directory, all files are at root level, and also there is no concept of created/modified time stamp.
