+# This file contains pin mappings for the stock 2021 Creality Ender 3
+# S1 & S1 Pro. To use this config, check the STM32 Chip on the
+# Mainboard, during "make menuconfig" select accordingly either the
+# STM32F103 with "28KiB bootloader" or the STM32F401 with
+# "64KiB bootloader" and serial (on USART1 PA10/PA9) for both.
+
+# For a direct serial connection, in "make menuconfig" select
+# "Enable extra low-level configuration options" and  Serial
+# (on USART2 PA3/PA2), which is 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 filename
+# must be changed to "firmware.bin"
+
+# With STM32F401, you might need to put "firmware.bin" in a
+# folder on the SD card called "STM32F4_UPDATE" in order to flash.
+
+# See docs/Config_Reference.md for a description of parameters.
