Connect to ESP8266 running micropython from PUTTY
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.
