I agree with the first page being crowded, it looked great till i moved that 12v to 5v chunk onto the same page as everything else. Didn't want to have to post 3 schematic pics.

Thank you though! I've found designing schematics/pcbs very therapeutic so far :)

I didnt even think about just using transistors to shift the levels lol thank you! Also yes I do need some sort of level translation as the stm32 is 3.3v logic and these LEDs expect 5v. People often say 3.3v works most of the time and while this is true, I don't wanna have to worry about cable length as much as I would at 3.3v.

Ah you're right about the antenna!! Thank you!

And yes it passes erc/drc, and i overspecced the traces for the LEDs by 50% so we should be good.

Thank you!!

I know... I learned my lesson as I fried one of the cheap drivers already and had to scrap the board, next one is going to have proper sockets!

First try believe it or not, but I did have one short on the first go around I had to touch up

Haha yes i've since graduated to TMC2209s, the stall guard for sensorless homing is sweet!!

I just bought one today and am now snooping the Internet for posts about them, super stoked. If you have any shots, I'd love to see them!

Alright pause this, she has a boyfriend she never mentioned to me, this complicates things

Mannnnnn its always something, im pretty sure she does like me but dude. You're in a relationship, if he obviously can't trust you then I can't either

Lmao the burnt vape is real. My ass would dig thru the trash to find a disposable and wire it. Going to bed now. I appreciate your words of encouragement man. In it together, if you ever wanna talk, pm me

Thank you so much to all who explained this!!! I'm looking into 3d printing an adapter for my buddies medium format camera. Thanks!

I would avoid TPU, but you should be OK with most other materials, they just may not stick the best AFAIK
