KOOBOOK 3Pcs PCF8591 AD-DA Converter Module Analog to Digital Digital to Analog Conversion Module for Arduino

description: The PCF8591 is a monolithically integrated, individually powered, low power, 8-bit CMOS data acquisition device. Voltage range: 2.5V-6V.The PCF8591 has four analog inputs, one analog output, and one serial I2C bus interface. The three address pins A0, A1 and A2 of the PCF8591 can be used for hardware address programming, allowing access to eight PCF8591 devices on the same I2C bus without additional hardware. The address, control, and data signals input and output on the PCF8591 device are serially transmitted over a two-wire bidirectional I2C bus. The left and right side of the module, respectively, outside the expansion of 2-pin connector, respectively, as follows: Left AOUT chip DA output interface AINO chip analog input interface 0 AIN1 chip analog input interface 1 AIN2 chip analog input interface 2 AIN3 chip analog input interface 3 SCL IIC clock interface on the right then single-chip IO port SDA IIC digital interface connected MCU IO port GND module to ground VCC power interface external 3.3v-5v Module a total of three red short-circuit cap, respectively, as follows: P4 connected to P4 short-circuit cap, select the thermistor access circuit P5 connected to P5 short-circuit cap, select the photosensitive resistor access circuit P6 connected to P6 short-circuit cap, select 0-5V adjustable voltage access circuit We highly appreciate all customers opinions to improve the selling, also if anything you unsatisfied, please contact us for probable best solution.
