Share. We’ve gotten used to the GPIO-available functions of Raspberry Pi computers remaining largely the same over the years, which is why it might have flown a little bit under the radar: the Raspberry Pi 4 has six SPI controllers , six I2C controllers, and six UARTs – all on its 40-pin header. You can’t make use of all of these at once. Or (with the file system tutorials) qemu.
