Product Details
The Gravity GP8503 is a top - notch 2 - channel DAC module that uses I2C communication. With a 12 - bit resolution and an impressive 0.1% precision, it's a perfect fit for control projects running on a 3.3V power supply, like those using ESP32, Raspberry Pi, or STM32 microcontrollers. This DAC module series can be controlled via I2C or PWM signals to generate voltage or current outputs. It offers multiple output signal ranges, three resolution options (8 - bit, 12 - bit, and 15 - bit), and you can choose between single - channel and dual - channel setups. You can even cascade multiple modules for multi - channel output. Key features include support for 3.3V - 5V power supply, an output voltage error of less than 0.1%, and a 0.1% output voltage linearity error. It has two voltage output channels (0 - 2.5V or 0 - VCC) to connect and control standard analog voltage devices. The Gravity interface, I2C communication, and Arduino control make it ideal for automated programs. It's great for applications such as motor speed regulation, sound intensity modulation, indoor and outdoor luminance control, and display panel backlight adjustment.

Using the Gravity GP8503 DAC module is quite straightforward. First, connect it to a 3.3V - 5V power supply. Then, use the I2C interface to link it to your microcontroller, like an ESP32 or Raspberry Pi. You can use Arduino to control the module easily, which allows for automated program control. When using it, make sure the power supply is stable to avoid any voltage fluctuations that could affect the output. Also, be careful when connecting the wires to prevent short - circuits. For maintenance, keep the module in a dry and clean environment. If you need to clean it, use a soft, dry cloth. Don't expose it to extreme temperatures or humidity. If you want to change the output voltage range, refer to the product specifications and adjust the settings accordingly. And if you plan to cascade multiple modules, follow the wiring diagram carefully to ensure proper multi - channel output.
