MOC3043M:
- led trigger current : 5mA
- Input Forward Voltage : 1.25V

So, (3.3V - 1.25V) / 5mA = 2.05V / 5mA = 410 Ω
If we use 330Ω instead of 410Ω, we have : 2.05/330 = 6mA < 12mA.

ESP12F:
- GPIO max current : 12mA
- Operating Voltage : 3.0~3.6
- Operating Current Average value :  80mA
- Power consumption (worst case) Tx802.11b, CCK 11Mbps, P OUT=+17dBm : 170mA
- Peak Consumption: 500mA



Total power consumption : 6mA * 5MOCs + 500mA =530mA
*3.3V = 1.8W
=> PSU >= 2W
