The development board provides one, 2x25-pin, 0.10” (2.54mm) pitch header for

supporting application-specific daughter cards/expansion boards:

X33, Peripheral application header. Provides access to an 16-bit data bus, 10-

bit address bus, and control signals (such as CE#, IRQ#, WE#), as well as I2C and

power (+3.3V). Using these signals, you can connect Digi-specific extension

modules or your own daughter card to the module’s address/data bus.
