The left resistor is 10K pullup on CH_PD and the right resistor is 10K pulldown on GPIO2.
The middle resistor is probably a 0 ohms for optional 3V regulator that can be added at the back of the PCB.
Hi, it looks like that, but I'm guessing there is something on the back that is impotant as you wouldn't expect a pull down on GPIO 2. Both GPIO 0 & GPIO 2 should be pulled up (10k ish) for normal operation. This question has been asked times before but I haven't seen this board.
In general you should be looking for:
Vcc -> 3.3V
GND - > GND
CH_PD - > 3.3V (possably via 10k)
REST -> 3.3V (possably via 10k)
GPIO 0 -> 3.3V (possably via 10k)
GPIO 2-> 3.3V (possably via 10k)
GPIO 15 -> GND (possably via 10k)
Theres more to this than meets the eye.
"Board is similar to this:" we need a photo (link) of both sides of the board you have purchased.
