The I2C-USB Kit allows one to test, tune and debug hardware and software of a PSoC application by bridging the USB port to I2C. Populated with the CY8C24894 PSoC device. A wide variety of devices can be connected to the PC using this bridge. Among them are: EEPROMs, realtime cLocks, ADC/DAC converters, LCD displays, regulated DC/DC converters, port expanders and many other devices incorporating the I2C interface. The number of devices that can be connected is constrained only by the I2C address limit and physical ability of the I2C bus.
