Thanks for the help Jaroslav, Just making sure I keep the smoke in!

Hi Mike,
it's the same 5V which power the Raspberry Pi itself. The polyfuse limits the current on "1W 5V OUT" to 100 mA continuous.

Awesome thanks Jaroslav and scoobsalamander

Just to double check. Is that the 1-wire 5v or the gpio 5v? and how much current can the 5v provide?

Cheers

Mike

Hi Mike,
feel free to use the 5V output of the Monarco HAT. Alternatively, you can use the 24V OUT and a 3k3 resistor.

@scoobsalamander: Thumbs up!

Jaroslav

Thanks scoobsalamander,

Do you now if I can use the 5v from the Monarco Hat or should I supply a sepaerate 5v?

Cheers

With a series resistor of 470 ohm you should be fine I guess. This will guarantee the 5mA you need to trigger the MOC3023 and the digital outputs can handle a current up to 1A so no problem.

Hi All,

I need to PWM a MOC3023 optocoupler from the Monarco Hat. I'm not 100% sure on how to do this as the MOC3023 requires 3v3 and the digital outputs are 5-40V. Whats the best way the achieve this? The MOC3023 needs to be driven by 5mA.

Cheers

Mike
