HLK-PM01 AC-DC 220V to 5V


I’m interrest for this Part HLK-PM01-AC-DC-220V-to-5V.

I think the availability of this compact part should interrese many people.


It’s a compact power supply for arduino and atmega family.

I’ve read the design tutorial, but I don’t have knowledge or experience with “AI” or “Inkscape”. It’s too fastidious for me.

Thanks in advance

Here are the SVG files, can somebody else make the fritzing part file?

Necessity is the mother of invention. I just created the part. This was my first Fritzing part so it may not be perfect but I tried to be as accurate as possible with the dimensions (especially in the PCB view). Still, your mileage may vary.

Here it is, enjoy!



A very big thank you for your work.

Thank you all, of course for your work.

However, the dimensions for PCB look not correct. Did anybody succeed with this layout?


I thought this sounded familiar :slight_smile: try the one in here someone cut a board and discovered the mounting holes are too small and I fixed it for him. Don’t know if it worked or not though.

Hi !

I’ve buyed a PCB with this part and effectivly the whole are to small.
Vanep give me a new part in the post above and this one seems to be correct. For the moment, i’ve not ordered the new PCB but, when i print the PDF pcb, the holes arent correct !

When you print a pdf of the new part the holes aren’t correct? If so in what way are they incorrect? The new part looks correct to me as a gerber in gerbv. The hole is .035 (which is I believe what you wanted) and the pad spacing seems to match the drawing above i.e. 5.011mm between the narrow pads 15.38mm between the wide pads and 29.3878 mm between the two pad sets taking the x y coords from the drill.txt file and converting from thou to millimeters. I haven’t used the pdf conversion so I don’t know how that works.

No no no !!! With the new part, wholes are correct !!! The wholes whas too small with the part in fritzing !

Hi, there is a new layout, which I didn’t found somewhere. Do you know something about this also?


What is its model number? A search for HLK-PM01 comes up with the current part from 2018 not this layout. It is easy enough to make a new part, but a reference to where it can be found is necessary,


I didn’t found the source of this (obviously) brand labeled product. This here is just the reference to the store where I buy from time to time parts:

This should do what you want. As always before ordering boards print out the pcb footprint at 1:1 and check it against a real part. As well there are two holes shown in the diagram above that are currently only on silkscreen. The picture of the module shows no holes there, but if they are needed you can drag a hole from core parts over the hole in the silkscreen to drill the holes (they won’t be drilled by default!)

Wow! That was so fast! Thanks a lot!
