Adafruit 935 DAC Digital to Analogue Converter 12-bit I2C (MCP4725) - NANUK

Simply attach the board to the I2C port on your microcontroller MCU and send the value of output voltage you want. Select either I2C address 0x62 or 0x63, or attach 2 x DAC boards to the same MCU. If your MCU supports 3/4Mbits per second Fast Mode I2C (not Arduino), then the output voltage can be changed at up to 1.77MHz. This is a great little board for any project that needs a true analogue output. It's also very easy to use and requires only a few connections.
