This PCF8591 module operates on 3.3~5V,so can be used with an Arduino Due, Raspberry Pi or other 3.3 V development board. The DAC on the PCF8591 has a resolution of 8-bits, so it can generate a theoretical signal of between zero volts and the reference voltage (Vref) in 255 steps. There is also a temprature sensor and light sensor on the board so you get the current temp&light with this module.
