This 2-Channel I2C DAC module can output a voltage of 0-10V, which is a standard driver in industrial applications. It can be widely used with most 0-10V devices on markets such as light controllers, inverters, valves, pumps, etc, by Arduino programming.

Besides, this module supports 8 different I2C addresses, which can be changed using the on-board DIP switch, allowing a cascade of 16 devices.
