Peripheral (extension) headers
The development board provides two, 2x25-pin, 0.10” (2.54mm) pitch headers for
supporting application-specific daughter cards/expansion boards:
 X5, LCD application header. Provides access to the LCD signals and SPI signals
for touch controller purposes. Use with a Digi-provided application kit or
attach your own application board.
 X33, Peripheral application header. Provides access to an 8/16 bit data bus, 8-
bit address bus, and control signals (such as CE#, WE#), as well as I
2
C and
power. Using these signals, you can connect Digi-specific extension modules or
your own daughter card to the module’s address/data bus.
