uart

For multiple UART on RPi have a look at:

• SPI or I2C to UART:
  • Maxim Products
    • MAX3107 SPI/I2C UART with 128-Word FIFOs,
    • MAX14830 SPI/I2C Quad UART
    • MAX3110E/MAX3111E SPI/MICROWIRE-Compatible UART and ±15kV ESD-Protected RS-232 Transceivers with Internal Capacitors,
  • NXP’s I2C/SPI to UART/IrDA/GPIO bridge Products :
    • SC16IS762 Dual UART (SC16IS752/762 Product Page)
    • Sparkfun Breakout Board for SC16IS750 I2C/SPI-to-UART IC (Single UART)
• or use a Arduino Due or Mega.

Find more here: GPIO -> Multiple Serial Ports (UART)

Finally the Beaglebone Black has already 4 UART.
