a cape that provides 5V ttl compatible GPIO.  By using the PRUSS unit and a cape the BBB would be a cheap alternative to using expensive high speed digital IO cards. 

Here you go, with Shield I/O+ you can drive any 5V logic, 14 GPIO pins are PRU enabled. The adapter has Arduino compatible sockets. Another MCP23017 port expander gives you 16 additional 3.3V or 5V (voltage mode is software adjustable) GPIO pins.
