User Expansion Header

The EVM includes a 40-pin (2x20, 2.54mm pitch) expansion interface [J28]. The expansion connector supports variety of interfaces including: I2C, serial peripheral interface (SPI), I2S with Audio clock, UART, pulse width modulator (PWM), and GPIO. All signals on the interfaces are 3.3V levels.

To help clarify connectivity between this interface and the processor, the table includes the pin location of the connected processor in parenthesis '( )'.
