Debugging and Expansion Port Information for Expert users
Also included on the ARCADE are 2 expansion ports. These are connected directly to the
microprocessor pins. Enabling these ports requires reconfiguration and programming of the
ARCADE bootloader. The bootloader source can be found at:
https://github.com/KitronikLtd/kitronik-arcade-uf2-bootloader
Pin 1 Pin 2 Pin 3 Pin 4 Pin 5 Pin 6 Pin 7 Pin 8
Expansion Port 1 PA08 PA09 PA10 PA11 0V 0V 0V 0V
Expansion Port 2 PA12 PA13 PA14 PA15 0V 0V 0V 0V
For more advanced use, the debug port allows the user to customise the processor
bootloader code, using a SWD programmer. The port is designed for 2.54mm (0.1”) pitch
standard pin header.

The expansion port is designed to take 2.54mm (0.1”) dual pin headers.
Paired with each IO pin on the expansion port is a 0V connection. The IO pins are rated to 3V
max. See the pinout table for connections from the expansion ports to the microprocessor.
