Just loaded Mikes basic on this little bad boy...

Works great. Will play with code a bit and post more data.

Relay is on gpio 12, and green led is on gpio 13. - This unit does not have the RF control with key fob, but for $5, you CAN NOT BEAT THIS!!!! Has nice little power supply for AC and relay control.

Might have to flash the led to spit out the ip address once connected to your network, or something.... or just leave it as AP.

This is great. Can you provide some details and pictures of how you wired the device to be programmed. I might have to buy a few of them for some of my own projects.

Just check the photo on the page. The TTL serial are labelled. They go gnd, tx, rx and +3.5V. The button is on GPIO0 so you just hold it down to flash it. I have the first version and just used a normal $4 USB to serial port board, making sure it only has 3.5V output (not 5).

Does the unpopulated header give access to other ESP pins?
