  1. # This file contains common pin mappings for the BIGTREETECH SKR
  2. # MINI E3 v1.2. To use this config, the firmware should be compiled for the
  3. # STM32F103 with a "28KiB bootloader".
  4.  
  5. # The "make flash" command does not work on the SKR mini. Instead,
  6. # after running "make", copy the generated "out/klipper.bin" file to a
  7. # file named "firmware.bin" on an SD card and then restart the SKR
  8. # mini with that SD card.
  9.  
  10. # See the example.cfg file for a description of available parameters.
