Hardware availability @ JLCPCB #31

Open jacobcurulli opened 9 months ago

jacobcurulli commented 9 months ago

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!

JanM321 commented 9 months ago

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

florianbrede-ayet commented 9 months ago

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

This is from the TPS82130 datasheet: image

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

jacobcurulli commented 9 months ago

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? IMG_4285 IMG_4286

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.

florianbrede-ayet commented 9 months ago

I've updated hardware-tiny and created a PR: https://github.com/JanM321/esphome-lg-controller/pull/37

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.

kchen commented 9 months ago

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.

kchen commented 9 months ago

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.

JanM321 commented 9 months ago

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). boards photos... https://github.com/jourdant/esphome-lgap/issues/10#issuecomment-2264531969

This is much bigger issue than missing pinout labels. 22mm instead of 23.5mm :( I bought some "Narrow width version" by mistake... 20241001_110943 SBC-NodeMCU-ESP32_dimensions

I've ordered 5 PCB's (because MOQ) on JLCPCB, and I only need 2. In case anyone is interested, I'm willing to sell the other 3 at cost + shipping. I'm based in NL, so shipping within the EU is probably easiest.

Hello @bjw-s, I would like to purchase 2 units from you. I am located in the EU. Please send me an email so we can arrange the details.

Thank you.

Edit - bought 2 units.

Can't find in ease TLIN1027DRQ1. So trying to find more popular one. Kicad project for Tiny hardware for U2 contents TJA1027, but datasheet says that it has dominant time-out function. Or it has very large time-out, so it not a problem? Is it possible to use TJA1027 as replacement? or any other applicant?

Do you still have any spare? Will take 1 for my split. I am in Australia. Drop me an email on emailspam2024@gmail.com

Anyone looking to sell some boards? Happy to order some as well with other people, looking to split the cost a little.

PANASONIC EEEFC1C100AR 10uF 16V 45mA@120Hz ±20% SMD,D4xL5.4mm is not in stock, any other alternatives? Will this work (ST(Semtech) CK1C100MCRC54)? Sorry I have no experience in electronics.

Mrsash2020 commented 3 weeks ago

I am happy to have one. Does it com assembled? If anyone orders a few, happy to pay for one.

Ordered, only need 1 board. Will update once I receive them and then I can start shipping out the other 4 boards.
