- Wed May 06, 2015 11:59 pm #16757 Just saw Adafruit began to sell ESP-12 board at $6.95/pc
A de-capped photo shows the flash chip is a WinBond (W)25Q32FVSI(G). The same page also claims the modules comes with 4MB flash.
Just wonder does this applies to ordinary ESP-12 and ESPD-12E?

P.S.
If nobody had ever decap them to check, I will decap mine tonight.

I rebuild the AT firmware example in SDK 1.0.1, choose QIO/4096 flash, and upload using FLASH_DOWNLOAD_TOOLS_v0.9.6_150419, doesn't seems to have any problem.
Any particular test you want me to try?

Baoshi
