A few time ago, I received some of these modules from Espressif. I don't know how these modules should be connected, I have tried different pin configuration on these modules and at least I could flash them with another firmware but they doesn't do anything, just show a line of garbage in the terminal.
I'm using a USB-TTL with a power regulartor LD33V, also I tried with my Arduino UNO.
I have not encounterd those boards but they look good!
