The PCF8591 Module is a breakout/prototype board based on the PCF8591 IC, a single-chip, low-power CMOS data acquisition device. It integrates four analog inputs, one analog output, and an I²C bus interface, making it ideal for applications requiring analog-to-digital and digital-to-analog conversion.
With three address pins (A0, A1, A2), up to eight devices can be connected on the same I²C bus without additional hardware. The device includes analog input multiplexing, a track-and-hold function, an 8-bit ADC, and an 8-bit DAC, supporting flexible data acquisition and control applications.
This module also integrates a photoresistor, thermistor, and adjustable potentiometer for real-time sensing of light, temperature, and voltage.
