PCB orders and status

[eabase]

I would love to order a PCB with all the components already included and placed.

1. What is the current design status of PCB?
2. From where can we order these PCB's?
3. Can they get both made and populated?

[justLV]

Pending any hardware optimizations (as mentioned in other issue you opened), I'll open the Crowd Supply campaign. They'll take care of all fulfillment and buy up inventory so that I can just place a batch order, making it simple to order from them.

[DanielHabenicht]

Hey @eabase, sorry for hijacking the thread. I'd also like to try out the PCB but PCBWay only lets me order 5 at a time.
If you or anybody else is interested and geographically near (Germany). I can purchase 5 and distribute them.

That would be 17,39$ per Unit + Shipping

Hi! Count me in (Netherlands), I would like to buy 1 or 2 pieces

[davenewham]

@DanielHabenicht does that include component cost? I think that might be additional...

Even so, I wouldn't mind taking a couple from you

[DanielHabenicht]

@DanielHabenicht does that include component cost? I think that might be additional...

Ahh, yes! I did not notice the 0 for Component costs. I added them to my cart now so they will be reviewed and component cost will be added. I will update this thread then.

[DanielHabenicht]

I've got the final price:

181$ for 5 ≈ 36$
If you are still interested just write back.

[davenewham]

@DanielHabenicht sure, but that still seems like pre tax and shipping so I expect it to cost even more!

In that case, I would only really be interested in one PCB for the time being (if that's OK)

[jwhengeveld]

Yes! I would like one piece!

[DanielHabenicht]

Alright, if there is one more who wants a piece more I will order.

[Uriziel01]

@DanielHabenicht I would like to buy one, I'm located in Poland. Did you used the latest revision avilable (it was updated 9 days ago)?

[Uriziel01]

I've also tried exporting the BOM and pick&place files to try JLCPCB and the cost seems a little bit better at around $120 but currently they don't have the MEMS and I had to replace one of the inductors with a slightly higher capacitance one + crystal oscillator is not exactly the same, probably not the best idea to experiment when this will be the first iteration and if something is wrong I'll have nothing to compare any measurements against 😉 Maybe it's a interesting concept for the future, PCB quality (especially silk screen) if slightly worse in JLCPCB but the price is almost always better for simple PCBs.

[justLV]

Feel free to, only thing I'd caution is to make sure JLC gets the part placement correct & the correct parts, sometimes their library parts are really badly named. Had issues where they put on incorrect components, and didn't follow the specified rotation of U1 even after manually confirming which was painful to rework.

The MEMS mics are probably the most expensive part at $5 per PCB so that's probably some of the difference

[Uriziel01]

@DanielHabenicht I've just got back my final price from PCBWAY and it's almost $200 😁 So I'll definitely take 1 from your order please. Just let me know how to pay you and whats the price for shipping from DE -> PL

[DanielHabenicht]

Sorry, I did not have time in the last few days. If anybody is more knowledgeable about all of this I am happy for somebody else to order.
It's the first time for me and I literally just clicked on the order link on the shared project from this repository: https://www.pcbway.com/project/shareproject/Onju_Voice_d33625a1.html (which should be from the release 9 days ago)

I've just seen they also changed the Crystal oscillator on my order.
I uploaded the xlsx so you can have a look.
T-1E4W641674A-5sets-onju-voice-bom(2023-10-11).xls

[Uriziel01]

I sadly don't have time to handle this and then also handle shipping all the boards to all of your guys, so please feel free to make an order in pcbway and I'm more than happy to pay your. Thank you.

[DanielHabenicht]

Sure, I am happy to order and distribute it to you. I just want to be sure to order something that works. So, is the change of the crystal oscillator ok?

[Uriziel01]

Nice, they replaced it with 12uF one, even when seiko epson does produce identical 10uF variants (Q22FA12800101) or even ABRACON with lower/higher ±ppm but not one with different spec, have no idea how load capacitance affects freqency and/or frequency stability, but I would rather not thest this on my own first batch PCB, just to be on the safe side.

@justLV You've designed it, you're the expert here, help 😄

EDIT:
Looking at ESP32 spec they do in fact insist on the 10uF, 10ppm crystal.

Hi @DanielHabenicht , do you happen to have one more spare to share? :-)

You can surely have one, but I haven't ordered yet. I don't know wheter the substitution of the one component would be working, so until I can confirm it working or get the right part I won't order.

Ah, I was hoping you wouldve gotten an answer by now. If you do find the answer and order a batch, I'd like to get one off you.

[TheZoker]

I'm also very interested and I live near Munich 👍

[ezerez]

I just got a quote back from PCBWay and they dont seem to have changed anything on the BOM. Do you have to check the components one by one if there was a change or do they remark when they dont have something in stock? Duty pre paid to Germany would be 244 USD for 5.

[pl0ink]

I suggest you all wait a moment before ordering the PCB's.
I just received my order from PCBWay and there seems to be a problem with the PSRAM.
I have tested 3 boards, all have the same issue: Memory allocation failed!
Will investigate further in the weekend.

Well turned out to be user error. I used an other board as devboard before and it uses a a different PSRAM mode.
After setting it to the correct PSRAM mode it works, and audio replay works.
Mic not working yet, probably screwed something up with pin def.
Will update.

Well, my mistake again.
To make the Mic work you need to attach the small ribbon cable connecting the Mute button and power connector.
Without this connection the ESP board is on constant mute.
But because this ribbon cable and the connectors are very fragile and you can not access the USB connector when the Nest mini is fully assembled, you might want to develop and test with only the USB cable and speaker attached.
To temporary ignore / disable the mute function just comment out this line: // pinMode(MUTE, INPUT_PULLUP);

Anyway, the boards I got from PCBWay appear to work well, build quality is very good.
I'm happy with them, sorry for the confusion. :-)

[qnlbnsl]

Anyone wanting to group buy in US? I want to get a few of these as well.

[bedbug1226]

Would be nice if someone just ordered a butt load and sold them on etsy or something.

[LordNex]

I just put in an order or I’d join you. Waiting for the review to finish. If you don’t go gold. You can get them down a little cheaper Benjamin T Powers On Nov 5, 2023, at 10:05 PM, bedbug1226 ***@***.***> wrote:  Would be nice if someone just ordered a butt load and sold them on etsy or something. — Reply to this email directly, view it on GitHub<#8 (comment)>, or unsubscribe<https://github.com/notifications/unsubscribe-auth/ACGXNJE3P5FNK74N525N5M3YDBHYFAVCNFSM6AAAAAA34K6S4SVHI2DSMVQWIX3LMV43OSLTON2WKQ3PNVWWK3TUHMYTOOJUGA2TCNBZHA>.

[dpetrillo740]

I'm also interested and in the US.

[LordNex]

Was looking at 5 myself. But the initial build plus components was like +$150USD. It may be smarter for us to group together and import and resell these Of course we still need a source for containerization of both the firmware and case design but we would just need to find a source. Obviously giving a good % back to @ justLV. I don't have an 3D printer yet or we could LiDAR the basic design and thing-a-ma or PCBWay the plastics. I have 4 I need to replace. I'd love to do my Lenovo Google Display somehow. Benjamin T Powers On Nov 7, 2023, at 7:10 PM, Dave Petrillo ***@***.***> wrote:  I'm also interested and in the US.

You have to look into the BOM Excel they provide (under "Quoted BOM" Button). It is not displayed in the UI if they change something. If there are no entries in the "Actual Purchase Mfg Part#" Column then they used exactly the specified components. That's at least what I hope (I have no experience with ordering these).

If we are getting more and more people it should probably get cheaper...

Hi,

I just received 5 cards for a total of 45CAD each, I need to test if I'll will be able to make them work in the home mini (1st gen). I guess it could works but not have the time to try to put it back together, anyway the 2 first card that i configure works well. (not a huge fan of the sensibility of the wake word, but it's already better than the esp32-s3-box3, sound is better too).
So I'll keep you updated in any case, but if you're interested for a few card (I might have 1-3 available depending on my test result). I'm in montreal, QC CA
For me the experience with pcbway went really well. if many people want to actually buy card i could be ok to resell them (if that could help)

What ESP chipset did you decide on?

[bobzer]

What ESP chipset did you decide on?

I didn't choose I just use the default bom, but in the details i can see the exact version is : ESP32-S3R8

[LordNex]

Just wondering. That's what was on my BoM as well and will probably be the best chipset. Not sure if it's possible but it might be worth it to see if one can be made with an olimex PoE chip as well so that all the serial functions are directly transferred via Ethernet instead of relying on WiFi to make the connection. This should allow better use cases if Bluetooth needed to be ran on the same box. From mt expirence at least with the lower power ESP32 WROOM, there's really not enough power or memory to run both wifi and Bluetooth button mention the rest of the code.

[don86nl]

No problem, @LordNex . Thanks for the additional tips and info. I might reach out if I need some more technical help. Im no electrician, just a hobbiest 😅.

Olease keep us updated, @bobzer . I have gen1's, but would need to get gen2's when I place the order. Would be nice if those could work too.

[K3kouse]

Hello :)

Just a quick question about the group Order.
Is it still planned or is it already done and I missed something ?
I didn't followed everything and the last comment about the group Order was by you don86nl asking a deposit before January 7th...

I'm too late I guess :/

[Uriziel01]

@K3kouse Thats right, for the time being @don86nl already did a group by for EU users, you'll have to wait for another one.

[LordNex]

@K3kouse Thats right, for the time being @don86nl already did a group by for EU users, you'll have to wait for another one.

I gave up on my USA order. Couldn't get enough people to commit and I'm leary of buying 5 just for myself to find out that they won't do what I'm looking for or fit right or something. I haven't been too impressed with HA's voice pipeline even after adding in ChatGPT. And then your, I could be wrong, but just a voice assistant and no longer a media player as well. I've done some testing just with my Muse Luxe and it's very problematic at best.

Unfortunately, I think keeping the Google integrations in with a Nabu Casa subscription the easiest at the moment. The Google pucks I'm using I assume are v2, and are still working for the most part with Google HA integration. Plus I have a Lenovo Google Display for my living room so I wouldn't be able to completely drop Google unless I could build a new PCB for it. At least this way Home Assistant is still in charge of things but I can also use them as Music players

On a side note I don't know if they are, but you might look into Music Assistant support for Onju as it's my defaco media player and I wouldn't be supprized if it isn't adopted by them officially

[don86nl]

Yes, Europe order has been placed and are under construction at this moment.

I agree that the assist pipeline is somewhat limited. However, we barely use google anymorw besides some basic commands I might be able to create.
For example, I created a goodnight routine which I also send in the voice assisnt contest. I will look into timers and alarms again and then 99% of google's commanda are replaced.
I do have to look into music playback, but I might use other, better speakers for that anyway.

[Nydid]

Guess i'll have to wait for the next EU Groupbuy.

[virusmoere]

I have 5pcbs spare without assembly (to dumb to order) . If anyone has the skill to solder them feel free to write me a message ;) (Location Germany)

[bobzer]

@don86nl I am partially successfull ... so the mic, mute button and speaker works but the touch button (volume up and down and action) don't works. About the leds, the 4 on the middle works perfectly but the 2 on the side are not on the correct side of the pcb so there are not visible.

Thanks for the update, @bobzer . Did tou have to modify anything to get it to work as it does right now? Those limitations are fine by me.

[bobzer]

@don86nl

yes, I had to solder cable and modify a little bit the board (understand drill to make the hole bigger)
sorry the picture are note really good but can help to get an idea


(the white cable is for the mute)

also no picture but i had to dremel cut a little bit the metal part that is between the speaker and the board (if you are still willing to do it I can open it back to take picture) and then isolate that metal (some tape)

[bobzer]

by the way if someone want some pcb I got 4 to sell
45 CAD + shipping
i'm in canada

[adoucette]

@bobzer

If the PCBs you have will fit in a 2nd gen mini then I'll buy one.

adoucette

[bobzer]

All the pcb are the one from this project (so the nest mini 2nd gen and not the google home mini 1st gen)
I also have an empty pcb if someone can be interested for that (by empty i mean without any component)

That is a gen1 right?
could you post your mods/findings to #27 since this issue is totally taken over ^^

Hi don86nl,
do you have an update for the order? Did I miss something?

[don86nl]

Hi don86nl, do you have an update for the order? Did I miss something?

This order was placed somewhere in january. All participants received their item.

For future reference; It was a bit costier than expected, due to income tax. One unit will cost nearly 60 euro's (assembly, shipping and import taxes).

[PlanetSmasher]

Oh I thought I was included as my nick is in the spreadsheet.
well then I will hope there will be another round for germany / europe

[don86nl]

Sorry, I posted my email to reply to. The list was made by someone else. Hope you can do another group order. So far, the onju is performing quite well.

[luckyzor]

anyone consedering posting an order on Europe?
I need 2/3 pcb's
anyone have the files so I can check in jlcpcb the costs?
thank you
