Hello All,
I designed a custom PCB that was supposed to run an STM32F411RET6 off an external 8Mhz cystal oscillator.
This is the first custom PCB I have done for an STM32 chip, so I am never quite sure when I am having hardware versus software errors. I have attached some pictures of my PCB below. You'll notice a few "bodges":
· One of the VCC and VDD pins were swapped in the schematic, so I cut the traces and jumped the decoupling caps. I had to replace the main MCU entirely because of...
