Figure 2. I soldered the board, but the screen catastrophically ripped out.

Figure 4. Quentin kindly helped me salvage another board which had power issues.

Figure 5. Success! After this I ended up trading the SAMD board for an RP2040 to try working on pico architecture.

Figure 6. Due to the screen having ripped out certain connections in my board, I only had access to a few buttons. Limited by hardware, I made a morse code telegraph.
