8.20. Expansion headers

There are three expansion connectors on the PDK version of the Snowball. For the SDK version, only
the 1x16 2.54mm Prototyping Header is mounted.

8.20.1. Prototyping Header

This prototyping header is provided to allow a limited number of functions to be added to the Snowball
board. Below is a list of the different interfaces available on this header.

• I2C

• UART

• GPIO

8.20.2. 60 pins Top Expansion Connector

The main purpose of the expansion connector is to route additional signals from the A9500 processor.
Table  8.10  shows  all  of  the  signals  that  are  on  the  60  pin  expansion  header.  As  the  A9500  has  a
multiplexing feature, multiple signals can be connected to certain pins to add additional options as it
pertains to the signal available. The different columns in Table 8.10 show what other signals can be
accessed by setting the mux control register in the A9500.
