# This file contains common pin mappings for the BIGTREETECH SKR E3
# DIP. To use this config, the firmware should be compiled for the
# STM32F103 with a "28KiB bootloader" and USB communication. Also,
# select "Enable extra low-level configuration options" and configure
# "GPIO pins to set at micro-controller startup" to "!PC13".
# The "make flash" command does not work on the SKR E3 DIP. 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 E3
# DIP with that SD card.
# See docs/Config_Reference.md for a description of parameters.
# Note: This board has a design flaw in its thermistor circuits that
# cause inaccurate temperatures (most noticeable at low temperatures).
