s1-printer.cfg

# This file contains pin mappings for the stock 2021 Creality Ender 3
# S1. To use this config, check the STM32 Chip on the V2.4S1 Board
# then during "make menuconfig" select either the STM32F103 with a
# "28KiB bootloader" or select the STM32F401 with a "64KiB bootloader"
# and serial (on USB PA10/PA9) communication for both depending on the
# STM32 Chip installed on your printers Motherboard.

# If you prefer a direct serial connection, in "make menuconfig"
# select "Enable extra low-level configuration options" and select
# serial (on USB PA10/PA9), which is broken out on the 10 pin IDC
# cable used for the LCD module as follows:
# 3: Tx, 4: Rx, 9: GND, 10: VCC

# Flash this firmware by copying "out/klipper.bin" to a SD card and
# turning on the printer with the card inserted. The firmware
# filename must changed to "firmware.bin"

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