💬 HLK-PM01 breakout board

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 ?
Controller: Proxmox VM - Home Assistant
MySensors GW: Arduino Uno - W5100 Ethernet, Gw Shield Nrf24l01+ 2,4Ghz
MySensors GW: Arduino Uno - Gw Shield RFM69, 433mhz
RFLink GW - Arduino Mega + RFLink Shield, 433mhz -

@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 -
@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

@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?

@sundberg84 - thanks! but still schematic does not open correctly, remapping says:

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

@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.

Hello, thank you for the good job! Just one question, do you remember what is the size of the 200mA fuse that you put? (5x20mm Fuse? or other?) Thanks
@Almamater its a glas fuse with legs, so not a holder and fuse, that took to much space. Search axial lead fuse.
