2023-02-14 (Tu) EWC_Box Soldering fixes

I tried to load libraries for the screen, but it communicates with SPI, not I2C. The PCB silkscreen shows I2C connections, but I checked a previous project and confirmed that the silkscreen was inaccurate. I decided to move to the SD card reader, which also uses SPI.

I cleared an SD card, then added a text file with a few words and an empty folder. I loaded an example program to read the SD card, but it failed to initialize. I checked the connections and found a missing solder bridge, so the device was not getting 5V power.
Fifth from the top should be bridged

I went to resolder the connection, but the jostling broke more wires. I removed them since they interfered with the USB port and reconnected them where they were less troublesome. I may have mixed up the wires during the process because I still could not read the SD card.
