# This file contains common pin mappings for the BIGTREETECH SKR mini
|
|
# E3 v3.0. To use this config, the firmware should be compiled for the
|
|
# STM32G0B1 with a "8KiB bootloader" and USB communication.
|
|
|
|
# The "make flash" command does not work on the SKR mini E3. Instead,
|
|
# after running "make", copy the generated "out/klipper.bin" file to a
|
|
# file named "firmware.bin" on an SD card and then restart the SKR
|
|
# mini E3 with that SD card.
