Help ESP8266 adapter

Hi, I am fairly new to ESP but I managed to upload some code in it using Arduino and direct connection. I have bought this kind of adapter so I don’t have to solder wires directly to ESP8266-01 and remove it when done. However, I can’t make it work. I have already connected I0 to ground in the module, but the program still can’t upload. Anybody else who encountered this problem and managed to solved it? Thanks for helping out.

I managed to upload some code... but the program still can't upload.

Your post is very confusing, you seem to contradict yourself. Please try again to explain what you need help with.

Can you please post a picture of your PCB with the 8266 soldered on.

What other hardware are you using to program the 8266 from the Arduino IDE?

Thanks.. Tom.. :slight_smile:
