Came across this brilliant new tool that can be very helpful for many.
ESPConnect! Perfect for checking old boards before you get going. Very transparent and visual getting info about your board.

Had some issue with an older 8266 board and made it easier to get hardware data and to see other helpful information +
I manage to flash my pre-made ESPHome file and had it up and running.
Big shout-out to the creator !!!
