Gravity GP8413 2-Channel I2C to 0-5V/10V DAC Module

The Gravity GP8413 module is a high-precision 2-channel DAC module with I2C communication. With a resolution of 15 bits and an accuracy of 0.2%, it is able to generate analog voltage outputs of 0-10V or 0-5V. It is excellent for automation applications such as light control, frequency converters, valve control, and pump control. With Arduino programming, this product can control various 0-10V or 0-5V controlled devices. Thanks to the high precision and resolution, it is ideal for control scenarios that require a high signal accuracy, such as fine control of speed or angle.

Features:

• Supports 3.3V-5V power supply.
• Output voltage error below 0.2%.
• Output voltage linearity error of 0.01%.
• Two channels for voltage output, optional 0-5V or 0-10V.
• Gravity interface, I2C communication, Arduino-compatible for programmed automation control.
• 8 adjustable I2C addresses for simultaneous control of up to 16 devices.

Application examples:

• Automatic light adjustment
• Frequency converter
• Automatic valve regulation
• Automatic water pump control
