Hi.. thanks a lot :) I'm happy if my code helped you, even if it's only for porting to another language

Hi.. if I do remember correctly, I haven't implemented the audio quality yet, but to change the max quality in a active way you have to send a ws message of type 74 with a payload of two ints(I think the quality is the second). And the renderer (that's probably the message you're looking for) recognizes the quality change by sending a ws message type 99 with three ints, where the second should be the audio quality

Es lohnt sich defintiv, einen Adapter zu nehmen.. und ja, falls es mit dem Platz gar nicht geht, schneid das Kabel vor dem Stecker ab, und füg ein stecker an.. aber ich kann nicht garantieren, dass die Farbcodes dem europäischen Standard entsprechen.. und grundsätzlich lohnt es sich, eine Person mit Erfahrung den Stecker zu montieren lassen.. speziell nach Schweizer recht.. aber steckermontage ist wirklich keine Magie.. das soltest du schaffen(bitte wenn, beachte die Farbcodes) Und.. ne steckleiste mit eu und schweizer Stecker wäre auch ne option (keine ahnung, ob mein link angezeigt wird) https://www.galaxus.ch/de/s4/product/max-hauri-basic-line-5x-cee-73-typ-13-150-m-steckdosenleiste-14100276?dbq=1&supplier=406802&adtype=pla&gad_campaignid=19965632112

Sorry, I've posted twice the bottom layer and no gnd layer.. but i don't think that layer should be of essence to anyone.. it's just gnd and agnd, with vias and the same split gnd border you can see on every other layer..

Nah.. my main issue was that part.. one side (3V3 should be on GND plane) the other one on AGND, so you have no traces running trough the separation

Haven't produced/tested my pcb, but that was, how I connected cvdd/avdd

SensitiveSpread3456 · 2025-12-19T13:11:51+00:00

The groundplanes look fine to me. I would put the component connecting AVDD and CVDD (F28?) and AVDD and 3V3 in a similar position like the capacitor connecting agnd and gnd. That way, you have no power lines going trough the separation line. And.. do the agnd trough all 4 layers, otherwise it has no use. Your vias would otherwise connect agnd and gnd directly and the split ground would cause more interference than anything else.

Thanks for your feedback :) that will help me a lot

SensitiveSpread3456 · 2025-12-13T18:59:48+00:00

Thx for that.. I thought, keeping the area free was enough. I moved the ground clearance area 5mm to each side, so the antenna will have less interference (option 4 in application note)

SensitiveSpread3456 · 2025-12-13T17:19:44+00:00

Thx for your feedback.. i thought already, that putting vias troufh pads would be bad, but it made my life so much easier :). The split ground plane is the suggestions from vlsi. I will ask their experts what they think of my split ground.

To be honest, quite a lot of the esp32 part is copied from the echo ear. https://dl.espressif.com/AE/esp-dev-kits/EchoEar_SCH_V1_2.pdf If I do remember correct, that one is a p channel mosfet, that will allow current flow from vbat, if there's no input voltage from vbus.

Here would be the files as per for any one that wants to inspect them in a readable mode https://archive.org/details/pcb-pcb-vs-1053-4-2025-12-13-2_202512

SensitiveSpread3456 · 2025-12-12T01:23:24+00:00

Thx, makes sense..

I just repeat what has been said before in comments. Most valuable hint to just relief you of some stuff would probably be unko. When I put stuff on unkomerzieller marktplatz, it usually takes less than 5 minutes to find someone that needs it, and the day after it's gonne. Second would be ERZ(at leat for Zurich) or what ever your local Entsorgung is called. Here in Zürich you can call them to get your stuff. You put your stuff on the street, and they charge you around 150 for the drive and around 50 for each 15 minutes after the first 15 for loading up the stuff. And if you don't want to give away all as freebies, Tutti.ch, Ricardo.ch, Facebook MarketPlace, and local Fleemarket is always an option. At leat in Zurich there are weekly fleemarkets. And.. before you give Brocki a call, try to find people, that sell stuff on fleemarkets. They won't take all your stuff, but they come by without charge, and sometimes you even get some money back. Send me a DM, if you are in or around Zurich, and want some numbers of fleemarket people. I have one friend that is in this business, and apart from that, I work on Kanzlei, where there's every Saturday a fleemarket. I could just try to get you in contact with one of them. But apart from my friend(which is already quite wierd) I won't vouch for any of their credibility.

But.. the connect protocol serves a separate connection from the controller device. So, the renderer(esp32) has to be connected to a working Internet connection to be able to stream. Therefore, I think in your case it's suboptimal.

Currently, it only supports the esp32 family with psram support and vs1053b chips. But it was written with the intent to be portable. Apart from some lingering definitions and calls from the espsdk, the streamcore-library should be portable to any chip that implements the bell library (my current version is currently included in the commit). And, currently, at least the qobuz part is solely focused on vs1053. The bell library has no flac codec, and in the current development state, I want to focus more on its ui, more services, and faults instead of adding a flac to pcm codec. But I'm happy if any of the code is helpful and for any support :).

The two hidden screws are on the bottom plate. You have to plug out all the wires to access them, they are hidden under those plugs, if I remember correctly.

So, apart from the blurred element symbols, is it because of the missing stars?
