Ambient click carries the Melexis MLX75305 IC. It’s a CMOS integrated optical sensor that consists of a photodiode, a transimpendance amplifier, and an output transistor. The chip converts ambient light intensity into a voltage, using the mikroBUS AN pin for communicating with the target board MCU. The board is designed to use either a 3.3V or a 5V power supply.
