Very very close! It's actually the Elna DCK-3R3E224U-E. It's the same cap, just with smaller, single exit style terminals so the board footprint is much smaller. I also have a bunch of the Korchip version mentioned earlier in the thread on the way. They're both identical so whichever I can get cheaper will be what I use.
I didn't realize when ordering from digikey that despite being a Canadian site with a Canadian domain, all prices are in USD. Didn't find out until I got the PayPal receipt, so tonight I will be part sleuthing to find better prices.
Usually I use and recommend Mouse but they don't carry either cap. Worst comes to worst I can keep ordering from Digikey but I might have to ask $25 USD instead of $23 per dongle so I'm not in the hole for the first few batches. I'd really rather not do that though, so does anyone have any alternate suppliers they've had a good experience with?
I do have some good news though, it's pretty much a guarantee now that I'll be getting an Anycubic Photon in the next few weeks so I can print future batches myself. (And actually print in black and not just dark grey).
I know that eBay and AliExpress are way cheaper for parts but for shipping actual boards to anyone but me I don't trust them.
