Hi Hugo,

I think you could sell these with some refinement, it looks really good!

Incidentally some of the smaller USB sockets are easy to hand-solder, if you ever wanted to shrink down to those. There are (for example) micro-USB sockets with through-hole pegs to hold then in the right place, so they don't move around while soldering the surface-mount pins.

You should upload a video of the working board showing the blinking LED. From the larger photos, in close-up the soldering quality looks totally fine for prototypes. It's unfortunate that two boards don't work but it's common to have a high number of failures until you've refined your processes. I still have large numbers of failures too, especially when I try to do something new like use a different reflow method or very unusual SMD package and so on.

I tried soldering a BGA-like radio module, it was pricey (about $20 each) and one in five initially worked : (

Nice project.

I would like to mention I am exceptionally pissed at the CH340 for changing from wchserial1430 to random wchserial[random 2 digit number].

Ugh.

Cool project.

If you do spin the K9 card, you could use the ATMEGA32U4 (used in Pro Micro and Leonardo). It is a simpler schematic with no need for a separate USB chip and it allows the card to act as a USB HID.

It is all set up in Easy EDA here:

I would add a reset button as it is needed to get into programming mode.

Corgis are festive! This is a known fact.

Noticed in earlier comments that the CH34x chips weren't the most reliable, that's a bummer. I was very interested in their other USB-to-peripheral chips too. But given people keep using them I guess they're good enough for the price.

What a fun project!

You got me with the title! What an awesome idea.

Super cute too.

By the way, I totally agree with your comment on the SI Labs chip. I wish it came in something other than QFN. Even with my SARO (super advanced reflow oven), I cannot reliably solder them. Which is a shame, because I have much more success with their drivers than the CH340.

Ok, this blog has caused nothing but issues at home. My daughter loved it so much that now she wants one.... And I don't mean the Corgino, she wants a cute, fluffy, happy "bundle of Corgi". Ok, I have to admit, I want one as well, but our bird said "No" to getting one. The "Bird" is actually a bird (not a name I call my wife) and actually said "no". Why did I get a parrot, talks back more then the wife.

Heard the cute dog go "Arrrrrrfff ! ow ow owwwwwwwwwwwwwwwwwwwwoooooooooooo" when that USB cable was inserted. Wait unitl the CH340 is soldered in.

:-)

Glad they are friendly pups

So, wouldn't the Arduino be called a "Corgino"?

I love it by the way!!

Cool. A microUSB for connecting to the PC is handy. Could be hilarious depending on placement :-)

I was wondering if any of those dogs were yours. My son's Beagle likes to play chase with her Corgi friends. Both high energy breeds....

Nice looking PCB. Maybe you should have put the USB connector on the collar [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-99decf01-373c-4d51-a74f-ba9bdadae5b3/contentimage_5F00_938.png:16:16].
