    • # This file contains pin mappings for the Creality "v4.2.7" 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.
