PCF8591 Module AD/DA Converter with 4pin F-F Cable

The PCF8591 Module AD/DA Converter adds analog inputs and an analog output to any board with an I2C bus. Based on the PCF8591 chip, it gives you four 8-bit analog-to-digital inputs and one 8-bit digital-to-analog output. It is especially useful with the Raspberry Pi, which has no analog inputs of its own, and it comes with a 4-pin female-to-female cable for quick wiring.

PCF8591 Module AD/DA Converter Specifications

• Chip: PCF8591 8-bit A/D and D/A converter
• Analog inputs: 4, single-ended or differential (set in software)
• Analog output: 1, 8-bit DAC
• Interface: I2C (SDA, SCL)
• I2C address range: 0x48 to 0x4F, set by the chip's A0–A2 address pins
• Supply voltage: 2.5–6 V
• Cable: 4-pin female-to-female jumper cable

PCF8591 Module AD/DA Converter Applications

• Reading potentiometers, light sensors and thermistors on a Raspberry Pi
• Adding extra analog inputs to an ESP8266, which has only one ADC
• Generating a simple analog voltage, for example to dim an LED
• Learning how ADCs and DACs work in electronics classes

What's in the Box

• 1 × PCF8591 AD/DA converter module
• 1 × 4-pin female-to-female cable

Tip: Run an I2C scanner sketch first to confirm the module's address. Keep every analog input between 0 V and the supply voltage; powering the module from 3.3 V lets you connect it straight to the Raspberry Pi's I2C pins without a level shifter.
