# For the ZNP Robin Nano DW v2.1 board:
#   - Compile with the processor model STM32F401.
#   - Select the 32KiB bootloader,
#   - Select (Serial (on # USART1 PA10/PA9) for the communication interface.
# Note that the "make flash" command does not work with ZNP Robin boards. After running "make", run the following command:
# cp out/klipper.bin out/ZNP_ROBIN_NANO.bin
#
# Copy the file out/ZNP_ROBIN_NANO.bin to an SD card and then restart the printer with that SD card.
# See docs/Config_Reference.md for a description of parameters.
