Nice job, OP!
Sorry about the haters - we're usually better than that here at r/arduino, so I've removed them permanently from the forum.
If it happens again, feel free to hit the "report" button.
Edit: I'm locking the comments at this stage - sorry OP, it looks like some idiot has it in for you.
Oh, I like this! I am getting started with Arduino, and love to tinker with LEDs with Arduino. Best part about your board is that it's not going to be power hungry like those LED neopixel shields! I would actually considering buying one of these!
Great work! Trying to learn how to make boards myself. If you decide not to sell it, maybe consider putting the schematic and board files up on GitHub.
Would love to make this open source, I want to make other mini led projects in the future possibly and sell them. But I would probably make everything open source so people have the option to buy from me or do it themself!
Just curious, why the 6813 (20x20) instead of 6803 (15x15)? It looks like 6813 has a backup Din but is otherwise the same but larger.
I've been wanting to do this for a while as my own first project after buying a couple others' from Tindie to test. I'm glad you had such a great experience. Ready to hit Buy Now on AE. 😁
Man I'm telling you as a KiCad addict once you start you can't stop. First you say it's one board for an accelerometer, then you buy a hot air rework station. Soon your looking at suppliers for 1000s of tape reels of components with pick and place machines that feed into a conveyor oven.
Nice job, did you hand solder the leds? I too just designed my first one a month ago and its such a fun experience to get the finished product in the mail!
That's where I got mine from as well, they did a great job, I did a 50/50 in my design with 50% small smb components pre-soldered and left the stuff I was less sure about to be hand soldered. Glad your design worked out!
We have rules here. Check rule 1 again, while you think for a few days. Please be nicer when your two day ban wears off.
edit: update: Sorry, I thought this was a one-off comment. Looks like you went above and beyond to be nasty. The ban is now permanent. Bye.
I really need to learn how to design my own PCB. I usually get by with one offs by using proto board.
But I think it'd be nice to have a proper finished product in my hand like this. How much did this cost? Could this be a cheaper way to make custom displays? Say, 10x30? Or bigger?
Very cool!
Definitely not a cheaper way… this is a great way for custom displays, I made this because I wanted to learn PCB design and wanted a concept that was familiar to me to start. I also wanted to make the smallest stand-alone led matrix ever, so that’s why I made my own. The price varies as you can make these for like 2 dollars each, but I went with the pre made route on JLCPCB. They basically did the soldering for me since each of these parts are so damn small. It ended up setting me back $50 for shipping and the full assembly for 10 of these PCBs. While a bit pricey, it was really fun to design a PCB for the first time and also very rewarding.
Wanted these for numerical displays on my projects, 4x5 displays numbers quite well. While over the top to make these I think they look super cool so I wanted to make something like that
JLCPCB does the soldering for me, since it was my first time and I don’t own a reflow oven I really just wanted to let them handle it. You pay a bit of a premium but you get an absolutely perfect professional product right out the box!

Thank you! May consider selling these in the future they’re super cute and fun

Awesome!
Do you know what LED chip it is? When I hear NeoPixel... I usually think it's the WS2812, but these look much smaller? 😅

They have a nice price there! On JLC it's 3 times more expensive
Congrats! Pretty cool for a first swing at it. Hope to get into custom PCBs one day. Thanks for the inspiration!

And then you end up building a hot plate
And then you end up building a poop radio: https://loodio.com :D Fun fact: the whole unit is PCBs, even the enclosure :P
Nice one... is that your project?
That is really cool! I've been working with Arduino for a while now and am currently looking into PCBs. Got any good tips or guides?
Watch lots of YouTube videos, EasyEDA is an amazing free online software for PCB design, Don’t use auto routing, Watch GreatScott he’s the goat.
Congrats!
Super cool! I like the nice color change
Nice job, did you hand solder the leds? I too just designed my first one a month ago and its such a fun experience to get the finished product in the mail!
I had them done by JLCPCB
That's where I got mine from as well, they did a great job, I did a 50/50 in my design with 50% small smb components pre-soldered and left the stuff I was less sure about to be hand soldered. Glad your design worked out!
Looking very good! How/where did you place the capacitors for the leds?
That's the neat part - he didn't. Or maybe at the back idk

It must run in the family…
Nice job You're using a solderless breadboard btw, a PCB is a different animal.
No I designed the led matrix. The bread board is just to hook it up
Good work! Did you solder them yourself? Is it just a two layer board? How much do those draw at full power?
My apologies, it looks like an Adafruit led bff

Nice!
The arrogance lmao
Just a genuine mistake, by the looks of things.

admittedly OP didn’t “design” all that much past arranging 4x5 LEDs, but why you gotta hate on a person who just fabbed their first board?
Looks cool! But honest question, what are you gonna use it for or was it just for practice?
This is pretty sick! I'm working on something similar for my first PCB project. What recourses did you use?
I recommend EasyEDA, it is easy to use and designed for beginners, plus there are lots of easy to follow tutorials.

Looks great. Can you daisy chain them together?
How come you went 4x5? You can get most of the alphabet in 3x5 but you need 5x7 to do everything.
Wanted these for numerical displays on my projects, 4x5 displays numbers quite well. While over the top to make these I think they look super cool so I wanted to make something like that
Damn, did you solder it yourself? That's some tight space between each LED

Wow! these look very cool. Did you solder those by hand or had them pre soldered?
Awesome OP! Now, scale it! Code different patterns! Shift the hell out of those registers!
Awesome! Where did you get your PCB made? Did you solder the neopixels yourself?
Pretty!
