# Teensy 3.2 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/schematic32.gif>. The following table can be used to convert between the two. | PCB | MCU | Notes | |------- |-----|-----------------------------| | 0 | B16 | | | 1 | B17 | | | 2 | D0 | | | 3 | A12 | | | 4 | A13 | | | 5 | D7 | | | 6 | D4 | | | 7 | D2 | | | 8 | D3 | | | 9 | C3 | | | 10 | C4 | | | 11 | C6 | | | 12 | C7 | | | 13/LED | C5 | | | 14/A0 | D1 | | | 15/A1 | C0 | | | 16/A2 | B0 | | | 17/A3 | B1 | | | 18/A4 | B3 | | | 19/A5 | B2 | | | 20/A6 | D5 | | | 21/A7 | D6 | | | 22/A8 | C1 | | | 23/A9 | C2 | | | 24/A10 | | ADC0_DP0 in schematic *[1]* | | 25/A11 | | ADC0_DM0 in schematic *[1]* | | 26/A12 | | ADC0_DP3 in schematic *[1]* | *[1]* - Currently not configured and may require extra work to implement.
