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
