STMicroelectronics is extending its range of STM32 Nucleo development boards with scalable, small-form-factor variants to support the 32-pin members of its STM32 ... with a range of hardware plug-ins ...

The Arduino ... GPIO pins can run via internal peripherals at up to 100MHz, which is plenty to handle the 1MHz clock speed of the Game Boy’s bus. Logic levels are an issue, as the STM32 uses ...
