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


The module chip adopts PCF8951 and supports external 4-channel voltage input acquisition (voltage input range 0-5v).Integrated photoresistor, can collect accurate ambient light intensity value through AD, integrate thermistor, can collect accurate ambient temperature value through AD, integrate 1 channel 0-5V voltage input acquisition (adjust the input voltage through blue potentiometer).With power indicator (lights up after powering the module), with DA output indicator, when the output voltage of the module DA output reaches a certain value, the DA output indicator on the board will be illuminated. The higher the voltage, the more obvious the brightness of the indicator;.Standard double panel, board thickness 1.6mm, beautiful layout, through holes around, hole diameter: 3mm, easy to fix.PCB size: 3.6cm*2.3cm
