I wonder if the sdcard tray will pop out often by accident when the device is in use; like in a pocket of my trousers.
I think once a sdcard is inserted you do not change the sdcard often. I would put my whole music library on the card. Is there a mechanism to hold the sdcard in place? A security measure? Especially when you can use USB to transfer data on the device, I would guess that I need only to change the sdcard once in the lifetime of the tangara.

Heya, thanks for the question! We've designed the tray to be quite thin to prevent it from accidentally being pressed in, and it sits slightly shy of the case itself, so jostling in a pocket should be fine. You normally have to push the tray in quite a bit to get it to release.
I find I add new music often enough that having the sd card be easily accessible is ideal for me, but we encourage you to tinker with your devices to make them work for you. If you really wanted the additional security, you could use the open hardware files to design a new tray with an extra locking mechanism, or design a plug to replace the tray entirely and just cover the slot. In fact, I've already seen somebody design a case for Tangara with a sliding door to access the sd card instead of a tray.

Thank you for the explanation!

I thought it might be possible to also transfer files via USB. So when I buy a new record I could transfer it that way.

Thank you for providing the hardware files. That enables users. I already saw a working tangara from Taylor Hay. I have not seen it yet, but is there a place to find forks of tangara? So when somebody makes modifications to hardware, firmware or design they could list their fork in a place where all others list their modifications?

Yep, we do have USB file transfer too. It's a bit slower than directly writing to the card, but if you wanted to leave the card in there and use USB exclusively that would be an option too.

That's a good idea, if we have a lot of forks that people want to share we could set up a page or repo for people to put them so others can find them. 
I'd say the SD card is very secure indeed! I actually have to unscrew the bottom-left face screw to get the tray out sometimes. And there is *no way* the SD card will come out of the cover accidentally; it feels like I'm about to break my SD card to get it into the cover. I'm interested in these alternate designs...

Oh dear, it shouldn't be *that* tight a fit. The SD card cover is designed to be a tight fit on the SD card, but you shouldn't need to undo screws to be able to remove the tray from the device. That sounds like it might be a tolerance issue. Is this a stock case and cover (ie, polycarb case and cnc aluminium cover)?

Yeah, it's what came with the Tangara, but unless my sense of materials is off, I don't think the SD card cover is aluminum - it's a black plastic. I tried to bend out the fins a bit so it could slip onto the SD card a bit easier, but it didn't seem to change, and it's scary putting it on. As for the issue getting the tray out, I'd say the card cover doesn't perfectly line up with the hole in the case, so that the cover slips upward and gets stuck inside the case when I insert it, which is what requires the unscrewing.
[edit] Maybe it's black anodized aluminum? It's the same as the volume buttons and hold switch, but I obviously don't know materials!
Out of interest, have you tried flipping the cover upside down?
Also yes it's aluminium with black hard coat anodisation.

I just tried. It wasn't any easier to get onto the card, and I think it maybe flipped the issue upside down - the gap is now above instead of below the cover. It hasn't gotten stuck inside the unit in the first few pushes, though, so I'll take it!

When you say "The SD card cover is designed to be a tight fit on the SD card" is there a trick to getting the SD card into the card cover? I've been working on forcing it in for 30 minutes, and at this point I feel like I'm potentially damaging one or the other trying to make it fit. Since there's only the one card cover, I don't want to attempt to bend it with pliers, as if it breaks there's no replacement.

I've attached it to one microSD adapter, where it was a tight fit (very hard to get on, felt bad), and one SD card, where it was a very, very tight fit, felt very bad, and it scraped away a fair bit of plastic from the SD card before it would go on. I also tried to bend the legs on the cover a bit, but I didn't push hard because I also didn't want to break it. I'm sorry to say I don't have a solution, but you're not alone. I wonder if future production should widen the gap between the legs a bit.

Ok, yeah, I'm at scraping away plastic from the SD card and getting my grimy fingers all over the contacts. I guess I'll just continue to get more aggressive with it until it snaps in.

I'm really curious if the issue here is the SD cards, the cover, or both. If anyone has one that's a tight fit, and has some accurate enough calipers/means of measuring, it'd be really helpful to get a sense of if it's variance in the cards or if there's some covers that have too tight of a gap due to tolerance issues. The SD card is expected to be 2.1mm, which fits well with all the covers we've tried.
The way I generally put them on is to put one corner of the SD card in first, brace it against the side post, then push the rest of the cover over the other corner of the SD card. Kind of a rocking motion like a rocker switch. I've attached some photos to try show what I mean.

I'm getting 2.05 - 2.07 mm on my Sandisk card, and the same on my Samsung microSD adapter. Eek?

Sorry I meant 2.1mm not 1.2, oops

I'm using a Micro Center 512GB microSD card, with the included SD card adapter. My Tangara's SD card holder feels very loose, and I've had to perform fewer than ~30 SD card slot insertions while doing my initial tests of Tangara. It's loose enough for me to make the black SD card slot cover fall out if I hold my Tangara in one hand and strongly tap it against my other hand ~3 times.
It's also loose enough for me to see the cover start to wiggle less than ~1mm when I nudge the cover on either on the far left or right end of the metal slot cover.
