# This file contains common pin mappings for the BIGTREETECH EBB USB board.
# To use this config, the firmware should be compiled for the RP2040 with "USB".
# The "EBB Can" micro-controller will be used to control the components on the nozzle.

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