# This file contains pin mappings for the stock 2020 Creality Ender 3 | |
# Pro with the 32-bit Creality 4.2.2 board. To use this config, during | |
# "make menuconfig" select the STM32F103 with a "28KiB bootloader" and | |
# serial (on USART1 PA10/PA9) communication. | |
# If you prefer a direct serial connection, in "make menuconfig" | |
# select "Enable extra low-level configuration options" and select | |
# serial (on USART3 PB11/PB10), 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 end in ".bin" and must not match the last filename | |
# that was flashed. | |
# See docs/Config_Reference.md for a description of parameters. | |
