4. UPIO-USB-AUDIO I/O Card Overview

The USB Audio I/O card adds a microphone, codec, and headphone jack for audio development and an SD card
connector. The card connects to the I/O Card expansion slot on the UDP motherboard and provides complete
access to the MCU resources. Each expansion board has a unique ID that can be read out of an EEPROM or MCU
on the board, which enables software tools to recognize the connected hardware and automatically select the
appropriate firmware image.

Figure 3 shows the USB Audio I/O card.
