Gravity: 2-Channel I2C DAC Module (0-10V)， I2C 轉 DAC （2通道，0-10V）
DFR原廠 Gravity：2-Channel I2C DAC／I2C 轉 DAC（2通道，0-10V）電壓模組（相容於 Arduino） (DFR971)
［出貨清單］：
- Gravity: 2-Channel 0-10V I2C DAC Module x1
- Gravity I2C/UART Sensor Cable x1
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.／此外，此模組支援8個不同的I2C位址，可以使用板載DIP開關更改這些位址，從而允許級聯16個設備。
