New Pcf8591 module ad da conversion module mcu conversion module robot PCF8591 is a monolithic, single supply, low power, 8-bit CMOS data acquisition device. The PCF8591 has four analog inputs, one analog output and a serial I2C bus interface. PCF8591 the three address pins A0, A1 and A2 can be 2 for programming the hardware address, allowing access to the same I2C bus - PCF8591 8 devices without the need for additional hardware. The PCF8591 device on the input and output address, control and data signals are bi - directional two - wire I2C bus for transmission in a serial manner. PCF8591 key performance indicators: Single power supply PCF8591 operating voltage range of 2.5 V to 6 V Low Standby Current Via the I2C bus - serial input/output PCF8591 through 3 hardware address pins addressing PCF8591 I2C bus speed from rate decision 4 analog inputs programmable as single - ended or differential inputs Auto increment channel selection PCF8591 analog voltage range from VSS to VDD PCF8591 built - in track and hold circuit 8-bit successive approximation A/ D converter Through an analog to the output of the DAC gain Two baby description: A module chip PCF8951 4 - channel 2 module supports an external voltage input capture (voltage input range 0 to 5 v) 3 the module integration photoresistor, you can capture the ambient light intensity through the AD precise values 4 the module integrated thermistor temperature by exact numerical AD acquisition 5 the module integrates a channel 0 to 5 v voltage input capture (via the blue potentiometer adjustment input voltage) 6 the module with power indicator (the module after the power indicator towns) 7 the module with DA output indicator, the when the module DA output interface voltage reaches a certain value, the board will be lit DA output indicator, the who the voltage, the light intensity is more obvious; 8 the Module PCB size: 3.6 cm * 2.3 cm 9 standard double panel, thickness of 1.6 mm, nice layout, surrounded by a through hole, aperture: 3 mm, work fixed Three module interface description: This module expansion outside the left and right, respectively, two - way pin headers, respectively, as follows: DA output interface chip left produce AOUT AINO chip analog inputs 0 AIN1 chip analog inputs 2 AIN2 chip analog inputs AIN3 chip analog input interface. 3 Right SCL IIC clock interface connected microcontroller IO port SDA IIC digital interface connected microcontroller IO port GND Module to external ground VCC Power Interface External 3.3 v to 5 v Four modules use red short cap There are three red module shorted cap, respectively the function as follows: Connect the shorting cap P4 P4, select thermistor access circuit Connect the shorting cap P5 P5, select photoresistor access circuit Connect the shorting cap P6 P6, select 0 to 5 v Adjustable voltage access circuit Payment Policy: We ONLY accepted PayPal payment.
