Note from first Assembly

So I did my first assembly for the claw machine!.

FYI this is for my claw machine project. See it here - https://github.com/hamesjan/clawedtronics

Basically, I got it working ( kinda ).

I've learned a lot and I'm really excited to iterate on the PCB I had built. I wrote down some notes for what I have to fix - Ive written it here

Power decision circuit needed between USB and Power Supply power. Having both will cause back driving that blows stuff up

0.1 nf Capacitors are too small. Also there is order for 100nf capacitors in wrong size and 0.1u in right size, just use right size for all

Screw terminals for 2 are flathead screws. Dont have a flathead. Either change them to philips.

Also, It might be nice to just find the right 9x9 connector so it's an easy connection.

Buttons are the wrong footprint. Also Non inverting buffer is wrong, too small too.

Weird bug with the bootloader. Not sure what is happening with ESP but I can’t get into the app sometimes.

DONT Solder while power is on!!!! Also, get a power switch so I don’t have to keep unplugging and replugging.

Pull up EN and GPIO0

USB C has the wrong footprint, wrong holes so it's hard to fit.

Break out GPIOs use too small pitch, just standard breakout pins like esp32.

During assembly I blew up 1 motor driver, a resistor, and other stuff. I basically have no sure idea what happened - a couple of suspect reasons but I'm not experienced in electronics enough to say for sure. Think I might have to get an oScope and really apply my little EE knowledge to figure out what went wrong before I order the next revision. I'm kinda bummed this is the only way to iterate on HW, where I have to spend a bunch of money to buy parts, pcbs, etc. But I'm glad I got setup with assembly tools so I can not have to pay for those things now :)
