Artery AT32F435
Starting July 2022, the factory is supplying an enhanced MCU option: the Artery AT32F435. This MCU runs at 288MHz and has 384kB SRAM. It is enough for reliable operation, extensive image caching, and will allow for a wider range of firmware features in future. The enhanced firmware which runs on this MCU is called FlashFloppy PLUS (or FlashFloppy+).

This MCU is currently supplied on only one PCB type:

SFRKC30.AT4.35 (LQFP64): Based on the SFRKC30.AT4 described earlier. Features the KC30 rotary header. The Motor signal can be passed through to the MCU by strapping MOR on the rear jumper block.
