I recently got an esp-12f, soldered it to an adapter board and wired it the same as an esp-12:

High- VCC / CH_PD / GPIO2
Low - GND / GPIO15
I get nothing with this configuration, I've also tried pulling GPIO0 high and low with no LED and nothing comes from the COM port, I however know that the power pins are soldered correctly because it'll draw about 20ma and if I leave it connected for a few minutes it will start to become slightly warm, so what am I doing wrong? is it dead? I've only feed it the recommended 3.3V and nothing appears to be shorted out, so I can't figure out what's wrong... ideas anyone?

Is the Serial adapter 3.3v compliant?

Second, did you exchange the TX and RX connections? I've heard that there are some boards mislabeled where instead of connecting RX->TX and TX-> RX it is RX->RX and TX->TX.

Yes it is, I've already used it to flash and send a few test programs to an ESP-01 which works great.

I haven't tried swapping them however I double checked and it's labeled correctly, but yeah pretty sure that isn't the issue because as I mentioned earlier, I can't even at least get the LED to flash after giving it power, so it appears as if it has a booting problem or something like that..

I figured I'd mention that I linked VCC to CH_PD via 100ohm resistor and GND to GPIO15 linked via a 1k resistor.

Well I decided to finally give my board one last thorough check with a DMM and even though I saw it drawing current that one time, it appears that VCC isn't connected.. (or connected properly anyway) I can't get it to pass a continuity test no matter where I probe it, which sort of makes sense as it's one of the only real shoddy joints I made, (just my luck) I melted the contacts a bit...

My question now however is, can I fix it? I may have completely melted the contacts on either the adapter board or the ESP... and if it is that bad, have I basically bricked it? or is it possible to at least de-lid it and connect power directly onto it? If so where? its very hard to see the tracks.
