- Sat Oct 17, 2015 7:56 pm #31619 I ordered some 12-E a month ago,, the silkscreen says they are ESP-12Q

- Fri Jan 08, 2016 10:03 am #38216 I received Oak by DigiStump Kickstarter direct from China last night, and the daughter module (they call it Acorn) says "ESP-12-F" on the back. It appears identical to the photos linked above, except the AI Thinker graphics are replaced with digistump.com graphics, and the blue LED is unpopulated.

My guess is Acorn === ESP-12F with custom firmware.

- Sat Jan 09, 2016 11:15 pm #38385 How interesting, because I just came across this post from last June where digistump explained that they'd reworked the Acorn to be a drop-in replacement for the ESP-12, but with different internals.

Perhaps they decided the 12F was good enough as-is. Anyone checked their FCC filing?

I'm using ESP12F with Arduino IDE. Everything works well excepted SPIFFS, i use "ConfigFile" example.

If i choose the board Generic espmodule 4M (3Mspiffs), i obtain this error :

```
Mounting FS...

ets Jan 8 2013,rst cause:4, boot mode:(1,7)

wdt reset
```

If i choose other memory parameters, i obtain :

```
