Different board revision #11

Closed hboyd2003 closed 9 months ago

hboyd2003 commented 9 months ago

Hello, I looks like I have a different board revision than what is in the tutorial (although they are both v1). Below are some images of the board and info. I was able to trace the RX and TX to a empty through hole (labeled MCU_TP) which I soldered screw terminals to. Unfortunately, I was unable to figure out how to pull the RST pin for the wifi down. The rst pin now heads into an unlabeled chip. Luckily the code works on this board revision and I had no trouble with anything else.

RST pin to WiFi module is Q12. One of my machines is the same model as this.

Looks like the RST might even be broken out on that MCU_TP header. Lucky you!

Thanks for this information. I might create a project wiki to contain some of this information.

Added a wiki page with this information. Thanks for the contribution.
