ESP201 dev board - One more finding #1.

Good news today!

I have managed to find why the GPIO15 connected to the RED RGB LED was not working !

The answer was under my nose. DIP pin K1 (S2) must be on the OFF position. See the picture:

Cool !!!! Now I can fully test PWM on this board.

Remaining unknown items: RELAY (J) connected to GPIO16.  SOLVED !!! See link below.

UPDATE: triggering the relay is described here
