Gravity: 2-Channel I2C DAC Module

This 2-Channel I2C DAC module from DFRobot 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 the market such as light controllers, inverters, valves and pumps - all via Arduino programming with a compatible development board. This module supports 8 different I2C addresses, which can be changed using the onboard DIP switch, allowing a cascade of 16 devices. The module comes complete with a compatible Gravity I2C/UART cable. Connection Example Features
