I started to play arround with some ESP Models a few weeks ago and run into a Problem with the ESP-13:
Normally there is a CH_PD Pin, but I only see EN, which is maybe the same. The other pin I wonder about is TOUT I can't figure out.
Before I burn the chip I wanted to ask if it's right to connect EN to VCC?
Thanks for help!

Thx for the reply. I tested it and you are correct. En is ch_pd like I was guessing. Low for programming and high for normal operation.
Tout as AD converter I couldn't test yet but I'll check data sheet and try it later on.

Thx Moritz
