# This file contains common pin mappings for the BIGTREETECH SKR V1.4
# board. To use this config, the firmware should be compiled for the
# LPC1768 or LPC1769(Turbo).

# The pinout numbers (eg P2.2) come from this diagram - https://github.com/bigtreetech/BIGTREETECH-SKR-V1.3/blob/master/BTT%20SKR%20V1.4/Hardware/BTT%20SKR%20V1.4PIN.pdf

# See docs/Config_Reference.md for a description of parameters.
