I2C bus lines
The KAmodPCA9533 module is equipped with jumpers allowing to connect pull-up resistors to the positive power pole to the I2C bus line. The jumpers give the possibility of independent enabled of the pull-up for the SDA and SCL lines.
LED RGB
The KAmodPCA9533 module is equipped with an RGB OSTBMAS2C1A diode with a common anode. The diode is connected to the LED0, LED1 and LED2 pins of the PCA9533 chip with the use of current limiting resistors.
