Today I received the ESP-03 modules I had ordered from Shanghai. A nice little breakout for the ESP8266EX with ceramic antenna. Due to the 2mm spacing between the contacts on the sides, I had to bend the headers into shape before soldering them to the module.
As an initial function test I used the Bus Pirate in UART bridge mode to flash the latest NodeMCU firmware onto the chip.

Hi, interesting post!
I’m trying to do the same thing with my ESP8266 – to test it using Bus Pirate but I’m not getting response back from ESP8266 🙁
Can you post the sequence of Bus Pirate commands just to get to the point where I can send AT commands (maybe you could also show some AT example too)? I’m sure this would be interesting to many others too.
First choose the rate: ‘b’… (switch your terminal program as well)
Change to UART: ‘m’ choose defaults for the following questions but the last, there choose ‘2’ for 3.3V
Activate bridge mode ‘(3)’ then ‘y’
Now you should be able to communicate with the module.
I am trying to test ESP8266 using BP. My terminal Tera Tera looks like being frozen after accepting macro(3) under UART so there is no way I can write a command to ESP8266. If that’s normal how you communicate/write to ESP8266? Could you please advise how to go about it or point me to a solution.
Are the bitrates correctly set in the BP and your terminal?
