CE 351 Microcontrollers
Project ESP 32 SD Card Module

Unforetunetly I made a costly mistake in this project in regards to creating my PCB. Due to a mislabel of my second layer on my PCB 3.3V input is being shorted to the ground in my bottom layer. After looking at the PCB with Dr. Li, it appears that the rest of the board would have been in operating condition without this mishap.

Figure 1 and Figure 2 are updated images after the error had been found and changed. I had all SD card tasks on the esp32 working and ready for PCB testing, had it not been for the error I beleive the test would have been sucessful.
