Today I spent an hour and tweny minutes going over and checking my schematic for the PCB I am making which has a microcontroller, motor drivers and more. I checked over the schematic in a few ways, I put the schematic into claude and asked it for errors, I also manually looked through datasheets of the parts, and I researched more into the parts I was using. Here was the big things I changed.

1. To get code uploaded to the microcontroller I was previously using a chip to convert a USB signal into UART, which the microcontroller can read. The UART line for communication I was using was also shared by the raspberry pi, which complicated the design. To fix it I took out the USB and the USB to UART chip and decided to flash code to the microcontroller through the Pi. This simplified the PCB a lot.

2. I found out that the 5V to 3V3 chip I was using is kind of outdated and lacked modern features. So I swapped it to a better one and got that wired up in the schematic.

The rest of the fixes were all minor changed to other components.
