PCF8591 - 8-bit Analog-to-Digital - AD/DA Converter Module - I2C

A AD/DA converter module using PCF8951 chip. Supports external voltage input capture (input voltage range 0-5v) Integrated photoresistor for environment acquisition through AD Integrated thermistor, can capture the precise value of the ambient temperature through the AD The five-module integrated 1 channel 0-5V voltage input acquisition (blue potentiometer to adjust the input voltage) Power indicator LED DA output indicator LED when DA output interface voltage reaches a certain value, the voltage the greater the light brightness; Standard double-sided PCB, thickness 1.6mm, mounting through-holes with diameter of 3mm for convenient fix Technical data: Supply voltage: from 2.5 V to 6.0 V A / D resolution: 8 - bit Built-in oscillator Sampling rate: depends on the speed of the I2C bus Communication interface: I2C, address: 0x48 Built-in resistors: pulling-up data lines of the I2C bus Possibility to work: in 4-channel mode or with two differential inputs Tile sizes: 3.6 x 23 mm Weight: 5 g Pinout: AOUT Analog output.
