# This file contains pin mappings for the stock 2025 Creality Ender 3
# V3 SE with Creality V1.1.0 board CR4NS200320C14(SMT32F401RET6).
# To use this config, during "make menuconfig" select the
# STM32F401 with a "64KiB bootloader" and USB (on PA11/PA12)
# communication.
# Flash this firmware by copying "out/klipper.bin" to a STM32F4_UPDATE folder
# on SD card and turning on the printer with the card inserted. The firmware
# filename must end in ".bin" and must not match the last filename
# that was flashed.
# See docs/Config_Reference.md for a description of parameters.
