HALJIA PCF8591 AD/DA Converter Module Analog to Digital And Analog to Digital Conversion Compatible with Arduino

• The PCF8591 is a single-chip, single-supply low power 8-bit CMOS data acquisition device with four analog inputs, one analog output and a serial I2C-bus interface
• Three address pins A0, A1 and A2 are used for programming the hardware address, allowing the use of up to eight devices connected to the I2C-bus without additional hardware Address, control and data to and from the device are transferred serially via the two-line bidirectional I2C-bus
• Single power supply
• Operating supply voltage 2.5 V to 6 V
