DFR0552 Gravity: I2C 12-Bit DAC Module
US$8.75
DFRobot Gravity 12-Bit I2C DAC is a small and easy-to-use 12-bit digital-to-analog converter with EEPROM. It can accurately convert the digital value to corresponding analog voltage signal, which is useful in may creative projects and automatic control systems. Although an analog voltage signal can be generated by PWM with traditional controllers such as Arduino and Raspberry Pi, such signal is ROUGH and NOT ACCURATE. To obtain a steady and nice analog voltage signal, the DAC is the best candidate. In addition to be applied in automatic control systems, the DAC module can be used to serve as a function generator to generate sine wave, triangular wave and even arbitrary waveform (we provide a library to generate low frequency sin and triangular wave with just a few parameters).
