I use the same SONGLE relays:

@GertSanders thanks for this link.
So do you have working prototype? what board are you using? I am in middle of finalising components and trying to finalise design. With little knowledge of electronics my progress is slow.
Also for 220 to 3.3v there is another converter from Olimex https://www.olimex.com/Products/Power/PWR-90-240V-3.3V0.8A/
overall its abit smaller then Hi-Link... Hi-Link abit better because all covered and less dangerous.Please share if you have any design finalised.

@GertSanders @toabhishekverma Do you have the dimensions and/or holding resistance?
-
Sorry I didnt get your questions .. do you mean dimensions of 220-3.3v converter. Here they are.
output 2.5W 3.3V/0.8A +-0.2V size: 30x20x18mmI am not from electronics background so didn't get what holding resistance means?

@Yveaux Still no idea about it. Check link if you get something from it. what I know is it can bear up to 10A current and can be controlled using 3v .... my order still in shipping so don't know more then that.
@toabhishekverma Ah, ok. Didn't know they were still in transit.
Maybe @GertSanders has them 'on stock'?http://yveaux.blogspot.nl

Maybe @GertSanders has them 'on stock'?@Yveaux No, also still waiting for the order to arrive. But a coil resistance of 20-25 Ohm means driving the coil with a FET. Not directly from a atmega328 pin.

Correct. Here's how I wired the songle relay on my Lithium Ion Sensor PCB:

I wouldn't trust both of them when it comes to switching high amp devices over 3A. I think there is a reason no german electronics shop sells songle relays :smile:
Plus, relays from an electronics shop in your country might cost the same than the songle relays or will just be a tiny bit more expensive.
At least this is true for 5V relays. 3V relays are hard to find (at least in germany)

I agree, I plan to switch lights, so my preference goes to the 10A model, just to be sure. I have used the SONGLE 5V versions, and none have ever given me reason to doubt their quality. Since I found a 3V3 powersupply I want to try building a full 3V3 board. Should be fun.

@HenryWhite why do we need D1 Diode (if i am write) in that circuit? do this circuit will not work without diode?
(sorry dont know much about electronics) -

(sorry dont know much about electronics)@toabhishekverma https://en.m.wikipedia.org/wiki/Flyback_diode
in short: It is needed to protect the NPN transistor from damage.
The circuit will work without diode, But eventually damage the transistor. -
@GertSanders Have you breadboarded your 3.3V design? I'm a bit worried that removing linear converter will impair the performance of the our fussy nRF clones due to less power supply ripple rejection. I think those going for the ESP8266 are better off.

Anyone has an idea where to source the 5.5V varistor? I received a bunch from AliExpress following which seem to be broken.
I found this link http://www.farnell.com/datasheets/575651.pdf. However, there seem to be a bunch of 5.5 V varistor. Can anybody help me figuring out the right ones? -
