NXP Semiconductors interface demo boards include a broad range of products that easily evaluate and program I²C devices. These NXP Seminconductors interface demo boards include the OM6282, which evaluates the blink, dim, and color mixing features of the PCA9633 LED driver. The OM6271 demo board contains on-board LEDs that can be controlled by the bridge's programmable GPIO, and the OM6274 interfaces to the host processor with an I²C-bus interface and supports up to 8 selectable I²C device addresses via jumpers.
