+
+# This file contains pin mappings for the BTT SKR2 board. To
+# use this config, during "make menuconfig" select the STM32F407 or STM32F429 processor with
+# a "32KiB bootloader" offset, 8Mhz Clock reference, and USB PA11 PA12 communication.
+
+# To flash this firmware: copy "out/klipper.bin" to an SD card, rename it to "firmware.bin", and
+# turn on the printer with the card inserted. Upon successful upload, the firmware will be
+# renamed to firmware.cur.
