I don’t remember where I read this but it was advised not to use resettable fuses with the HLK. Basically it was said that if the fuse were to blow the HLK would have already been stressed to the point where it may be unsafe and it’s best to replace the whole device.

I wish I could remember where I read that but I’m not sure I believe eatasheet was saying that these small PSU’s don’t handle heat or spikes well and if the fuse goes, you should assume the PSU is unsafe as well and replace it. I think it was in lr33cz thread that he was replying to on a different forum but I could be wrong.

Here it le333cz I guess: HenryWhite it mean that appart if you make a direct shortcut with a metal part, the only thing that came make the fuse blow, it is because of the HLK part. Hi and thanks for sharing your project!!! I’m impressed with the 3D preview of diptrace.

I’ve imported your project since is almost what ,e33cz need, but I need some changes: How do I import this 3D part? Where’s can I find the Songle Relay part that has been shown above? Just one more question: After spending a few months on this forum and a few datasjeet later, I decided I wanted to build a small but cheap PCB which could be placed in either the wall behind the light switch, or above the lamp.

I eventually ended up with a PCB which is about 4 by 4. So with all components attached I’m hoping to get in stuffed in a 5x5x3cm plastic printed case.

Modules which I’ve used to power the board: The board has been tested in the past week, and everything is working as expected. Compared to the previous board I’ve posted, I have updated the following: Should make it easier to solder. Some 3D pictures Top and bottom: Is this a classic dumb move thinking that 0. I also ran out of 0.

Does the light switch need to be a SPST or can you use a pushbutton? Curious how this would work with a SPST switch. I haven’t looked at the code dagasheet see what is setup. This depends on the sketch you flash. I understand that the question has already been asked, but Is there a possibility to adjust the scheme to the ESP instead of Arduino? Anybody can tell or help – how to do datxsheet But I am datasheet to electronic designs. One diagram and circuit is explained here http: Ddatasheet Switch will notbe connected to mains.

And in Sketch i. I am looking to reduce its size more if possible and wish to le33cz ESP Also datasueet to add more then one relays to the board. In some rooms there are 3 buttons on one panel.

So thinking to use 3 relays. Will it be a good Idea? I think should not matter as long as I have enough GPIO to control relays and Electric wire connectors can bear the load. If we use this we may have to drop few things from 5.

Like no need of 5v – 3. If we use 5. Thank you for this pcb.

In which program did you do the design? Do you think you can share an editable version of the design? It is more expensive and bigger AC-DC circuit but since I hace some in my stash i would like to use them. That’s a link to your shopping cart, we don’t have access to I’m interested in the relay, can you post a working link? GertSanders thanks for this link. So do you have working prototype? I am in middle of finalising components and trying to finalise design.

With little knowledge of electronics my progress is slow. Also for to 3. Hi-Link abit better because all covered and less dangerous.

Sorry I didnt get your questions. I want to know the current flowing when the relay is active. Yveaux Still no idea datashret it. Check link if you get something from it. Didn’t know they were still in transit. Maybe GertSanders has them ‘on stock’? Didn’t even think of looking for a datasheet of a Chinese relay. Yveaux No, also still waiting for the order to arrive. But a coil resistance of Ohm means driving the coil with a FET.

Not directly from a atmega pin. I wouldn’t trust both of datasheer when it comes to switching high amp devices over 3A. I think there is a reason no german electronics shop sells songle relays. Plus, relays from an electronics shop in datazheet country might cost the same than the songle relays or will just be a tiny bit more expensive.

I agree, I plan to switch lights, so my preference goes to the 10A model, just to be sure. Since I found a 3V3 powersupply I want to try building a full 3V3 board.

HenryWhite why do we need D1 Diode if i am write in that circuit? 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. 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 ESP are better off. Anyone has an idea where to source the 5. I received a bunch from AliExpress following which seem to be broken. I found this link http: However, there seem to be a bunch of 5.

Can anybody help me figuring out the right ones? It will take a few more weeks to reach me. But then I will test it on my ac board. I will make a node with this converter version this weekend. It’s a pity that the chinese “varistors” seem to be jumpers. I even saw in some offers on AliExpress that they are referred to as jumpers.

How can I check whether the solid state relay works at all. My assembled board receives messages and sets state properly, I have 5V on the pin, however the relay does not seem to switch. Should I hear it? Any other ideas for “debugging”? It should be very high when “open” en very low when “closed”.

SSRs do not make sounds when they switch, so sound will not give a clue if they work. I don’t know if this has been answered already. But I have some major problems soldering the thermal fuse to the board.
