Yeah, so I guess we should just change nothing, right?
/s in case it wasn't blatantly obvious we are in desperate need of changing gun laws.
Un fucking believable.
Here are a few more views:
Greetings again! Yesterday I posted the schematic for this circuit, and today I have routed it as a 2 layer PCB. The intent of this board is for it to be a playground to build autonomous LED animations with the LP5812 ICs from TI, which seem pretty neat.
I'm hoping to get feedback on this design and sanity checks to make sure I haven't missed something when routing this out. I couldn't figure out how to upload multiple photos, so I'll add some more views in the comments. Cheers!
If you're interested in the KiCad files or other related things, I've got it on GitHub.
Yeah I hear that some people like to keep the bus pullups closer to the host. The other gotcha is that the voltage for the I2C doesn't have to match the VCC pin and I didn't want to assume that users would want those coupled together. Perhaps I can add some DNP resistors so users can have a choice of a pull-up on the dev board if they like.
Naturally, just like a making a pull request, I found that my annotations were incorrect for the LEDs (it doesn't functionally change the schematic) after posting. My intent is to have all odd LEDs on U1 and even on U2 so that when I place them in a circle it's easy to make usable patterns with one controller at a time as I learn how to use animation engines.
Greetings! I've been throwing this schematic together as I want to experiment with the TI LP5812 IC which is an i2c controlled autonomous matrix LED driver. I am a novice when it comes to electronics so I'm looking to see if I've missed anything in this demo board schematic.
The intended purpose of this circuit will be to provide a playground to experiment with different lighting patterns by allowing the user to interact with two of these LP5812 ICs over i2c as each can only drive 4 RGB leds each.
My main points of concern: Making sure that I haven't missed anything critical in the rather dense TI datasheet https://www.ti.com/lit/ds/symlink/lp5812.pdf?ts=1710689049125 as well as making sure that my schematic makes sense.
I chose not to include i2c pullups on this dev board as I felt that was best left for the host to configure, but I'm happy to learn. Thank you!

This update causes my Jetbrains IDE to randomly crash several times a day, it's great. Also my USB hubs wouldn't work this morning until I power cycled everything a few times. What fun!
Hard disagree, fold 4 gang.
I can't speak for the flip, but the fold 4 is fantastic. I can't imagine going back to a slab
Aww I didn't even know there was a Rock Band 4, I would love to play that series again but I can't find the band in a box anywhere, and based on the news, they're sunsetting the game too. How lame.
That was a neat read, thanks!
Howdy! There's some engagement for yah
Yes, I have to agree the problem is not just gun laws, and, in isolation, changes to gun laws would not fix the root of the problem.
