PCF8591 AD/DA Converter Module Analogue to Digital to Analogue Conversion NEW

PCF8591 AD/DA Converter Module Analogue to Digital to Analogue Conversion for Raspberry Pi Arduino NEW

The PCF8591 is a monolithically integrated, and a separate power supply, low-power, 8-bit CMOS data acquisition devices. The PCF8591 has the four analog inputs, one analog output and a serial I2C bus interface. PCF8591 three address pins A0, A1 and A2 can be used in hardware address programmed 8 PCF8591 device allows access to the same I2C bus, without the need for additional hardware. On the PCF8591 device input and output of the address, control and data signals are transmitted in serial fashion via the two-wire bidirectional I2C bus.

Module Features

Module chip using PCF8951
Module supports external voltage input of the 4-way acquisition (voltage input range of 0-5v)
The module integrated photoresistor by AD collection precise value of the ambient light intensity
Module integrated thermistor by the precise value of the ambient temperature of the AD acquisition
Module integrated 1 channel 0-5V voltage input acquisition (the blue potentiometer to adjust the input voltage)
Modules with power indicator (for the module power supply indicator lights)
Modules with DA output indicator, when the module DA output interface voltage reaches a certain value, will be lit panel the DA output indicator, the higher the voltage, the more obvious indicator brightness;
Module PCB size: 3.6cm * 2.3cm
Standard double panel, thickness 1.6mm, nice layout, surrounded by a through-hole, aperture: 3mm, convenient fixed
