I “cooked” a different angled 3d plastic case for my Zynthian Mini v2 build. The fit was slightly tight, but it fitted. Here are some pictures, along with my custom built analog ortholinear keyboard and an Exquis.
My build would surely benefit from the pcb plate/fascia, but for now I will not order 5 + steep delivery fees just for the looks.
It’s working “Okish” in USB Audio gadget mode (the undervoltage symbol is still there, but it seems to work).
Hi! Stupid question! I am building a Zynthian Mini. I have the rev 2 board where the audio board is positioned where the audio jack is facing the side of the case. Is the audio jack from the board used? Or is the audio routed to the 1/4" barrel jack right next to it? I have been scouring pics to figure out how people are building the rev 2, but not finding the right pics to make me feel confident. Please help!
Thanks!

You can connect to either. Audio out from card is routed to jack on PCB board. Clearly connecting directly to pcm5102 card mini jack is not going to be as robust to often plug in and out as it would be when using a proper 1/4” jack that can also be screwed to external case. You can not fix mini jack from pcm5102 card with screw to external case.
But if you don’t have jack to solder to pcb you can use mini jack on audio card.
Thanks for the info!!
Hi @stojos.
May I suggest the following changes to the “Building Zynthian Mini V2” wiki?
While building my Mini I made a couple mistakes. Specifically, soldering the sound card before the switches caused two switches to be very difficult to solder. Using male/female headers for the sound card avoids that pitfalls.
Where it says:
Then solder sound card. First solder male header pins that came with the card and the solder it to PCB board.
I would suggest to say:
Then solder sound card. There are two options to do that:
- Option 1 (strongly suggested): Use male/female headers to attach the audio card.
- Solder the male headers that came with the card to the pcb and use female headers for the sound card itself.
- Option 2: Soldering the sound card directly to the pcb
- First solder the switches that are covered by the audio card footprint.
- Check if the solder bridges on the bottom of the JA GY-PCM5102 are configured as in the following image
- Finally solder male header pins that came with the card and then solder it to PCB board.
Also, where it says:
Then solder the switches.
I’d probably say:
Then solder the switches. Properly align the switches and encoders (with the fascia if you have one).
I don’t have the rights to edit there.
I tried to update wiki but my edit access does not work anymore. Zynthian wiki says that I need to confirm my email address to be able to edit the content but when I try to confirm my email address I am not receiving an email with a link from zynthian wiki for confirmation. I have tried everything, even removing and adding email again, however whenever I try to trigger confirmation email from wiki it does not appear in my inbox or spam folder.
I am very interested in buying a board. Am I too late or do you still have one available?
Not worried about the jumper lead fix.
Cheers
If you want to order zynthian mini v2 PCB and it’s facia here is the link.
hello Stojos
I’d like to use a DAC with an audio out (i have an audiojoector but i could use the version of the bsaic dac with audio in). Is it supported natively ?
DAC is used to get audio out from zynthian (digital to analogue converter). ADC is to get audio into zynthian (analogue to digital converter). Zynthian only support one sound card so card need to have both: DAC and ADC chips on it. You cannot mix audio cards at the moment in zynthian. You can also use USB audio interface that often come with multiple audio in and outs.
On current mini v2 you will need to either use a single hifiberry card that has both dac and adc chips and connect it to 40pin connector on the pcb or use audio interface device plugged to usb. In both cases you should not connect pcm5102 card to mini’s pcb at the same time. USB interfaces have typically more latency due to USB protocol conversion but they are usable.
We have designed audio card using the cheapest dac and adc chips and developed driver for it but we are not selling this yet. It was more an exercise to test new rpi5 capability to support multiple dac/adc channels. There is a different thread for it.
thanks for your anwser. Perfectly clear now
hi I just ordered the pcb from the PCBway and would like to purchase the parts. it seems some of the parts are not sold or links are broken. plus theres no explanation for part number 21.
can i have alternatives links for these parts please?
Capacitor - Film - Non-Polarized
thanks in advance.
If you’re in the US, I ordered mine from Digikey at https://www.digikey.com/en/products/detail/vishay-beyschlag-draloric-bc-components/A104K15X7RH5UAAP/13279856
In fact I got all my components there.
thanks for the reply but I live in Malaysia. So links from Aliexpress is greatly appreciated.
At the least you can use the information in the link I sent to search for the part or some equivalent. Sorry I can’t be more help at the moment 
Most of cheap 100n film capacitor will work. Just make sure that spacing between pins are same or similar.
thanks for the clarification.
hi. can i get another clarification for another item please. Just to be doubly sure since its a capacitor …
the value stated is 100u.
may i know what volt is it? is it 10v?
so the part I should be purchasing is 100u 10v, ya?
thanks and have a nice day ahead.
10v is fine.
thanks for the reply! just ordered all the parts including a RP5 8gb. it does add up. i now understand why the Zynthian 5.1 is priced the way it is. I wanted to buy it in the first place, but the shipping to Malaysia was around 98 USD. oh well. very excited to pair the Zynthian Mini with my new Oxi One Mk2! 
And we look forward to hearing the result…
