| Feb 1, 2019 at 13:57 | comment | added | Gerben | Gray goes to IN2. Most of these boards have a jumper between VCC and JD-VCC. But you probably don't want that here. The opto-isolators led could light up if the pin is set to HIGH (3.3V) on the ESP. So the led will see 1.7V across it. | |
| Feb 1, 2019 at 13:49 | comment | added | Jaromanda X | I think the grey wire in the picture probably goes to vcc ... no wait ... that picture is hard to see ... the other issue the OP has is the lack of VCC as you poinbt3ed out @Gerben - that other VCC can be 3v3 (I know, because that's how I connected mine) | |
| Feb 1, 2019 at 13:45 | comment | added | Gerben | You need to connect the 3V pin to the VCC pin on the relay board. JD-VCC is just for the relay coils. Vcc is used for the optocouplers which currently don't have power at all, looking at the picture. | |
