💬 HLK-PM01 breakout board

Please follow the rules for using the CERN OHL. Details on this are on the forum: https://forum.mysensors.org/topic/3096/open-hardware-licensing
EDIT: Saw that you state you will update the license ASAP, so just take this as a reminder to do that
-
AAaaand... DONE
I just had to do dinner but @Anticimex you were quick 
-
Can I ask what the ratings are of the two capacitors used in your circuit? A 1000 uF and a 100 uF?
-
@arp5z5 it is added just to be able to smooth any DC power as needed. I would probably just go with a 0.1 and 10uF but it might be that you don't need any. If you are running a normal MySenwors node with only a temp the HLK module provides enough caps.
-
@sundberg84 Good to know! Thank you for the quick response!
-
Would you mind uploading the design files that include the capacitors? The photos contain them, but the Gerber files don't
-
Hi! Really? Im sure I have uploaded them.
Well, I will upload them again!Edit: All files removed and updated. New revision created.

Thanks for the excellent work!

Hi,
This is a 5V version. Did you consider doing a 3.3V version? I have pretty much all my sensors /GW using 3.3V power source
-
@alexsh1 the 3.3v uses the same pinout so you should be able to just change the hlk module ?
-
@sundberg84 thank you for pointing at this. I did not realise there is a 3.3v version :((
I have a few 5V ones which are useless without a voltage dropout
-
Thank you for sharing, what Varistor part number you are using?
-
@pihome im using the recommendations from this thread: https://forum.mysensors.org/topic/1607/safe-in-wall-ac-to-dc-transformers
Make sure you buy the right depending on what AC voltage you have 120/240 or other.I think these are the ones i bought last time.
-
Dear @sundberg84 can you please read and write here the Varistors exact model/part number from your assembled board, please?
-
@beic hi. Please see the thread above yours

HLK-PM01 breakout board:@beic hi. Please see the thread above yours
There is no value mentioned there, and how did you calculated the tp peak of the sine for varistor against mains?
You just trow some varistor value in there without calculating anything for RMS and Vpp?!
-
@beic - sorry, I missed your reply
I didnt calculate - it depends on your AC, depending on your locations so everyone using this PCB has to get their own MOV.I have followed the collected recommendations from this thread: https://forum.mysensors.org/topic/1607/safe-in-wall-ac-to-dc-transformers
Im happy to learn more about varistors (haven't got that far in AOE yet
) so please inform us if you know more that would be usefull here. You can use the thread above.The varistor was recommended here: http://lygte-info.dk/review/Power Mains to 5V 0.6A Hi-Link HLK-PM01 UK.html

Hi @sundberg84, did you create custom components for this design? Can you add your library files to the download, please?
-
@ru64 - i tried uploading them but openhardware didnt allow it.
@hek - is it possible to allow these?.dcm
.lib
.kicad_mod
-
Yes, should be possible to allow those file extensions. I'll take a look at it tonight.
-
Could you give it another try try uploading the files. They should work now.

@sundberg84 - thanks! but still schematic does not open correctly, remapping says:
Warning: No symbol “HLK-PM01” found in symbol library table.
Warning: No symbol “CONN_01X02” found in symbol library table.

Warning: No symbol “C” found in symbol library table.Any ideas? Sorry if asking stupid thing, but I am really new with KiCad
-
Oh, ok, never mind. Apparently, it does not work correctly in the latest KiCad version. When I open it in 4.0.4, it looks fine
-
@sundberg84 can you please tell me what is the type or specifications (other than 600mA) for the output fuse? Could you name a specific fuse as an example?
Thank you.
-
@ab192 - I put that there because that is the limit of the HLK-PM01 output. I never use it though, (i just bridge it) and use the input-fuse... When you choose a fuse its much about what kind if load you are going to have on that circuit.
