The MAX471 voltage and current sensing module is designed for electronics enthusiasts and engineers who need reliable, precise measurements. It provides voltage measurements from 3 V to 25 V and current measurements up to 3 A, making it a practical tool for accuracy in a range of projects. Voltage sensing is implemented with a resistor divider design that scales the red-terminal input by a factor of 5, enabling safe connection to lower voltage electronics. This module can be used to test both current and voltage in circuits, supporting straightforward debugging and validation of power and signal paths. Electrical and compatibility notes: - Analog input range: 0 to 5 V - The voltage sense input should not exceed 5 V x 5 = 25 V; for 3.3 V systems, inputs should not exceed 3.3 V x 5 = 16.5 V Use scenarios: - Monitor a battery pack or power rail up to 25 V and current up to 3 A in hobby robotics or DIY projects - Bench test and debug development boards powered from 5 V or 3.3 V, using the 5x divider for safe voltage measurement - Educational experiments to demonstrate voltage dividers and simultaneous voltage/current measurement This description preserves the original model, functions, and specifications while presenting clear, customer-friendly benefits.
