+# This file contains the configurations and pin mappings for the
+# Tronxy X8 using the CXY-V2-0508 board.  To use this config file, the
+# firmware should be compiled for the AVR ATmega1284p, 16MHz.
+
+# Some Tronxy printers come without a bootloader present on the
+# board. In that case, use MCUDude MightyCore ATmega1284p bootloader
+# with TQFP44 Sanguino pinout. The package can be found at
+# (https://github.com/MCUdude/MightyCore).  Follow Klipper install
+# instructions but instead of "make flash FLASH_DEVICE=/dev/ttyACM0",
+# use the following command:
+# avrdude -p atmega1284p -c arduino -b 115200 -P /dev/ttyUSB0 -U out/klipper.elf.hex
+
+# See the example.cfg and example-extras.cfg files for a description
+# of available parameters.
