UnbufferedSerial: Similar to BufferedSerial, but intended for applications that are short of RAM and cannot afford buffering or that need more control of the serial port and use it from IRQ.
QuadSPI (QSPI): Provides functionality to configure and access QSPI devices connected over a QuadSPI interface.
