Hardware availability @ JLCPCB

[jacobcurulli]

Hi,

I'm hoping for some help with the tiny hardware PCB. I've gone to order from JLCPCB but they don't have stock of the PANASONIC EEEFPC220UAR Capacitor. I've had a look but can't seem to find a suitable replacement as I'm not sure how far I can deviate from the specs. Does anyone more knowledgeable know what other capacitor might work?

Thanks!

@florianbrede-ayet do you still remember how you selected this one?

[florianbrede-ayet]

@jacobcurulli I think I would just choose C178597 as replacement - although it's a little expensive @ $0.20 .

This is from the TPS82130 datasheet:

For our requirements, you can likely get away with any SMD,D4xL5.8mm capacitor that is 10+ μF at 10+ V.

Thank you for the help @florianbrede-ayet and @JanM321
I’ve ordered the PCB’s and I’m excited to get it up and running.

Has anyone tried getting an advantage air zone controller into home assistant?

Great. Please let us know if it works.

I haven't heard anything about this as part of this project. Some LG duct units and controllers also have support for zone control, but it's not implemented in the controller because I don't have experience with or access to such units.

For what it's worth, I ran into a similar JLCPCB supply issue, and used EEEFN1V330R which seems to work fine. It's a 33 uF capacitor instead of a 22 uF one, but that seems probably fine based on the following portion of the datasheet:

8.2.1.2.3 Input and Output Capacitor Selection
For the best output and input voltage filtering, low-ESR ceramic capacitors are required. The input capacitor
minimizes input voltage ripple, suppresses input voltage spikes, and provides a stable system rail for the device.
A 10-µF or larger input capacitor is required. The output capacitor value can range from 22 μF up to more
than 400 μF. Higher values are possible as well and can be evaluated through the transient response. TI
recommends larger soft start times for higher output capacitances.

Can you please advise me what to replace Shenzhen Kinghelm Elec KH-2.54FH-1X19P-H8.5?
These are now sold out.
What about this one https://datasheet.lcsc.com/lcsc/2306091006_HCTL-PM254-1-19-Z-8-5_C2897382.pdf ?

Yes, that part (C2897382) looks very similar and seems to be a good replacement (although I didn't compare the datasheets in detail). Please post here if it works so we can help others in the same position.

I've updated hardware-tiny and created a PR: #37

• C3 has been removed. As quoted above, the datasheet mentions a 22uf (HF) ceramic capacitor which is part of the reference design for ESP32 DevKits. The electrolytic output capacitor is not required.
• C2 had already been replaced with a stock part in the previous PR
• Small schematic fixes (PinSocket -> PinHeader, "No Connect")

All parts are currently in stock at LCSC - but it's fluctuating frequently. Maybe PCBWAY is a better manufacturer for the PCBs - the gerber, bom & position files should work for them as well.

For anyone considering JLCPCB vs PCBWay:

JLCPCB was about $60 for 5 for me, including shipping. I received a quote from PCBWay (but did not complete an order), and PCBWay was $99.33 for 5 ($15.43 component cost, $30 assembly cost (which looks like it gives you free shipping?), $53.90 PCB cost). Don't know how much PCBWay is for a different quantity.

PCBWay seemed to be a more manual process after uploading the files, but that also meant that they took the BOM containing LCSC part numbers, and figured out what parts they should actually use.

I guess PCBWay is $30 for assembly for 1-20 pieces, so I guess that price is fixed, and probably the component costs scale linearly.

That's also my experience: PCBWay is able to order parts they don't have (or propose replacements) but they're more expensive than JLCPCB and a bit slower. It was worth it for me when I started this project but it's great we now have a PCB that can be assembled by JLCPCB.

I wonder if there are good options for doing a bulk order of > 100 PCBs and DevKits and selling them somewhere. Maybe eBay or Tindie but I don't have the time to send packages every week and deal with problems.

I can confirm that C2897382 work well.

FYI in case others find this here, I placed an order on JLPCB for 20 boards - I need 3 for myself, likely with 1 or 2 spares.
Once I get them and install/test 3, I can sell them at cost (buyers will pay for shipping&packing, but I think that should be super cheap as small/lightweight).
Note: I also replaced the out-of-stock C1 with a same size similar specs 10uF capacitor. (these components are +-20% anyway, and the circuit likely does not require something too precise).

I would be interested in two pieces

I am supposed to receive them today. So I hope to install and test tonight. If all goes well, I'll post here.
Question: would you need a cable made? I likely have enough connectors (to be verified, but for my Voron printer and some RC stuff, I got many connectors) and a good crimper.

Note: I never tried it, but see if you can PM me. I'd rather not write my personal email here directly :-)

Cabel would be fine. I use one with LG PREMTB001 in slave mode so cable (socket splitter) with two connectors on one side and one on the other.
I did not find PM but my email is rudolf.kotulan at outlook.cz.

I got my 3 indoor unit working with the boards.
Cables: I will likely not build special cables with some kind of socket splitter.
Anyway, I just need to price that stuff (Add all I spent :-) )
How many boards, and will that be shipping (from the USA) to the Czech Republic? (not super sure about the country name, please assume I mean well).
