  1. MOC3043M:
  2. - led trigger current : 5mA
  3. - Input Forward Voltage : 1.25V
  4. 

  5. So, (3.3V - 1.25V) / 5mA = 2.05V / 5mA = 410 Ω
  6. If we use 330Ω instead of 410Ω, we have : 2.05/330 = 6mA < 12mA.
  7. 

  8. ESP12F:
  9. - GPIO max current : 12mA
  10. - Operating Voltage : 3.0~3.6
  11. - Operating Current Average value :  80mA
  12. - Power consumption (worst case) Tx802.11b, CCK 11Mbps, P OUT=+17dBm : 170mA
  13. - Peak Consumption: 500mA
  14. 

  15. 

  16. 

  17. Total power consumption : 6mA * 5MOCs + 500mA =530mA
  18. *3.3V = 1.8W
  19. => PSU >= 2W
  20. VTX-214-003-103 : 3W noise/ripple 3.16<3.3<3.43
  21.
