<![CDATA[Omron SSR with 3.3V node]]>Guys,
I like the Omron G3MB-202 SSR
So far I have used these on 5V arduinos
I am now moving on towards my next project (touch wall switch) and would like to go for 3.3V nodes
Any of you using these SSRs with 3.3V trigger ?
Thanks a lot for your return ;)

Great!
Orders on the way then!!

I suppose transistor is here for the case when your board signal voltage is too low compared to the voltage of the SSR as the necessary current for SSR is low.

Thank you for sharing your experience
There are resistors and transistors on the relay board... I guess the relay is triggered via a transistor then...
Do you run the relay itself (black bloc only) straight from the arduino output?

I have not had any problem with those relays (at least the cheap clones from aliexpress) when running the full board at 3.3V (using HLK-PM03).
