Super Blue Pill¶
The board uses an STM32F103C8T6 in a LQFP48 package. The front UART1 pins are Serial1 in Arduino.
For the board to work (properly) in Arduino, you need to burn the latest STM32duino bootloader, which can be found here: • https://github.com/rogerclarkmelbourne/STM32duino-bootloader/tree/master/binaries • The board uses the 'generic_boot20_pa1_button_pa8.bin' binary.
See the 'Introduction to the STM32 Blue Pill' page under 'References' for instructions on how to update the bootloader.
