# Teensy LC onekey

To trigger keypress, short together pins *D5* and *B2* (marked on the PCB as *20* and *19*).

## Hardware

### Pins
When setting matrix pins, you need to use the MCU definitions instead of what is printed on the PCB. Sourced from <https://www.pjrc.com/teensy/schematic_lc.gif>. The following table can be used to convert between the two.
