2023-02-15 (W) EWC_Box SD card reader level shifter

I double-checked my connections with a multimeter by tapping the Arduino pins from below and confirming they landed on the SD adapter and were in the correct places. I searched some forums and found that other people connecting similar hardware used a level shifter successfully. I found one in my stock and soldered a mixture of regular header pins and extended ones.

When I soldered wires to the prototyping shield, I used short wires and had to add extensions. This was good news because I spliced the level shift into the circuit without much trouble. I had to swap some wires on the secondary side, but everything should be run correctly. Despite the new hardware, I could not read an SD card.
