AJMRTC PCF8591 Expansion Board, ADC DAC Analog IO Module with LED GPIO Test Pins for Raspberry Pi, PCF8591 Analog to Digital Digital to Analog Converter Sensor Board

AJMRTC PCF8591 Expansion Board is an analog IO learning module built for Raspberry Pi beginners. The production part number is PCF8591-PI-IO. This board uses the PCF8591 chip which provides four analog-to-digital input channels and one digital-to-analog output channel via I2C communication.

It comes with onboard LEDs and GPIO test pins, allowing users to easily test digital IO status and verify analog readings. Developers can connect analog sensors such as photoresistors, thermistors and variable potentiometers to collect analog data, or output analog control signals.

This module is widely used for embedded learning, sensor data collection, simple analog control experiments. Basic I2C driver configuration is required. Raspberry Pi mainboard is not included.
