A breakout board with the MCP4726 / MCP4822 DAC from Microchip. (the MCP4726 is I2C, the MCP4822 is SPI). 

The PCB is equipped with two I2C/SPI connectors, so chaining multiple modules is an option.
This allows you to control this board with only 2 data lines (I2C) or 4 data lines (SPI). This makes it possible to chain multiple modules without the need for more IO pins!
The board can be used with all microcontrollers, such as the Atmel AVR, Arduino/Freeduino boards, Microchip PIC, etcetera. Othercomputers/boards with an I2C interface (such as the Raspberry Pi) should also be able to control this module.

Please note that the picture shows the SPI version. (chip with 8 legs, I2C version has 6 legs). 

The module comes with all connectors pre-soldered
