Unless you bypass the polyfuses it will max at 1.25A. It is designed not to fry your prototype together with your house

You playing with fire, lol. Trust me, have your ruses right. I almost burned my parents house once

Thanks, I had forgotten that the atx breakout gives resettable fuse protection - good to be reminded - I have no desire to let the magic smoke out of my house

The Raspberry Pi that I'm using to connect to the ESP-03 takes the place of the more usual FTDI USB bridge - and the Raspberry Pi is fixed at 3.3V logic. So in this case I don't need to worry about level converters or dividing the voltage down with resistors etc.

Thanks for all the suggestions, no breakthroughs yet, but I'll try again with another module (I bought four) just to spread my chances.

SUCCESS!! Oh sweet joy!

I tried another module - this time I didn't bother soldering and just used a set of probes I bought from Electrodragon at the same time:

I found the modules had firmware 0018000902-AI03 shipped - I was able to upload lua firmware onto it no problems!

Many thanks to everyone who contributes to this great forum!

I'll have another look at the dodgy module - starting to suspect my soldering
