I2C Demonstration Board 2005-1 Quick Start Guide

Hardware description

Figure 2 shows the following items on the hardware:

• USB Port: port where the USB cable is plugged into the board.

• USB_LINK LED: this green LED will illuminate when the cable is connected between

the PC and the hardware.

• remote sensor diode: where the remote sensor diode is plugged into the board to

allow the SA56004E temperature sensor to monitor the ambient temperature.

• microcontroller: a socketed microcontroller is provided to ensure easy service in the

event of damage to the device.

• extension connector: this connector is used to connect future daughter cards targeting

specific Philips Semiconductors I2C-bus devices.

Remark: Philips recommends connecting only daughter cards developed and provided by

Philips Semiconductors to the extension connector. Philips Semiconductors is not

responsible for damage caused by other target cards.
