PCA9956B demonstration board is an add-on to 9 pin connector of the NXP I2C demo board 2005-1 or Fm+ I2C bus development board. This daughter board makes it easy to test and design with the PCA9956B, a 24-channel fast-mode plus (Fm+) 57 mA constant current and outputs allow up to 20V for LED supply. This demo board along with the Win-I2CUSB Lite GUI (PC based) provides an easy to use evaluation platform. This board features LEDs for colour mixing, blinking and dimming demonstrations. A graphical interface allows the user to easily explore the different functions of the driver. The board can be connected in series with other I2C demo-boards to create an evaluation system. The IC communicates to the host via the industry standard I2C-bus/SMBus port. The evaluation software runs under Microsoft Windows PC platform.
