# STM32F103 with a "28KiB bootloader" and serial (on USART1 PA10/PA9)
# communication.
# It should be noted that newer variations of this printer shipping in
# 2022 may have GD32F303 chips installed and not STM32F103. You may
# have to inspect the mainboard to ascertain which one you have. If it
# is the GD32F303 then please select Disable SWD at startup in the
# "make menuconfig" along with the same settings for STM32F103.
# 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
