serial to esp-12f

[waspie]

i'm trying to get something out of a esp-12f module. can i connect this with a regular serial port on an older computer?
should it work with a regular usb->serial port adapter?

i can't seem to get anything out of it or program it. do i need a *special* serial adapter or something?

you need a usb-to serial adapter with 3.3 V like this one:

... but for starters i would suggest a esp8266 board with buildt in usb-to-serial like the wemos d1 mini:

shortly after i posted this i ended up coming to the understanding that there was a big difference between rs232 and ttl. i hopped over to microcenter and got a ttl serial adapter on my way home from work. i was able to successfully flash it within minutes after beating my head against the wall the past 2 days not being able to communicate with this module

all is well
