I am attempting to connect to an ESP8266 Board running micropython with no luck. I have erased and flashed per the instructions in the docs and all instructions found on internet. See below (this is on Windows 10):

The board has AMICA printed on the back. See pic of the front.  It is connected on COM3 via USB.
When I connect to the board with PUTTY I get gibberish and the terminal is non-responsive.
Putty Serial Settings:
Speed: 115200
Data bits: 8
Stop bits: 1
Parity: None
Flow Control: None
When I hit reset on the board the gibberish on putty terminal clears and more appears.
Any thoughts on where I am going wrong?
For those other newbies out there who stumble across this with similar problems...
I bought a new board, flashed it as above and connected with putty with the settings I have listed above with no issues. So I am guessing a bad board. Finally, I can get back to programming in Python.

 Infinity CliffTry change your baud rate to 9600, it eighter runs on 115200 or 9600. if it looks like gibberish try change it. As a starter
Flashing the board with micropython solved the gibberish problem for me

 Zack KeyzolI also had some Putty issues. Turning off Flow Control in Putty helped everything tremendously. I still get a line of garbage on a reset, but after that it all works flawlessly.
