DF Robot Gravity I2C Digital Wattmeter

Working with electronics can be complex, but that's part of the excitement. The precise requirements, limitations, and unique considerations make it a specialized and intriguing field. This is where specialized modules, like DFRobot's I2C Digital Wattmeter, come into play. These tools provide detailed insights into the power usage and behavior of your projects, ensuring they receive the right amount of power and are functioning as expected without exceeding their power limits.

The I2C Digital Wattmeter is a valuable addition to nearly any electronics project, capable of measuring power consumption up to 26V and 8A. Beyond displaying the wattage drawn or supplied by batteries, circuit components, solar panels, and other power sources, it also features voltage and current sensing. This allows you to accurately assess the performance at different points or circuits within your project.

Note: To achieve optimal accuracy with a tolerance of around ±0.2%, it’s recommended to perform a simple manual calibration before integrating these wattmeters into your projects.
