- A computer hardware device that provides serial communication for debugging
- Transmission speeds and data formats are configurable
- This device looks different on all devices, can be hidden, removed, or modified
- Four pins, however we ONLY need to worry about three of them
- RX, TX, and GND (VCC is not important to us)
- NOTE: They are often configured in different orders from board to board, so troubleshooting with a multimeter is required prior to testing!

"Paper Clip Bridge"
A standard interface used to connect microcontrollers to other devices
- Classified as an uncommitted digital signal pin
- Found on integrated circuits and electronic circuit boards
- Used as an input, output, or both
- No explicit predefined purpose and are left on the board unused by default
