Key Features:

Voltage and Current Measurement: The MAX471 module can measure both voltage and current simultaneously. It's often used to monitor the supply voltage and the current flowing through a load, such as a resistor, LED, or other electronic components.

Maximum Current: The MAX471 is typically rated for a maximum current of 3A (amperes). This means it can accurately measure current in circuits with currents up to 3A without exceeding its specified limits.

Analog Output: The module provides an analog voltage output proportional to the measured voltage and current. This output can be interfaced with an analog-to-digital converter (ADC) on a microcontroller or read by other measurement instruments.

High Precision: The MAX471 is designed for high precision, allowing for accurate voltage and current measurements.

Voltage Reference: Some versions of the MAX471 module might include an onboard voltage reference. This reference voltage is used to calibrate the measurements for better accuracy.

Zero Current Output: When no current is flowing through the module, it should ideally provide a zero current output (voltage signal) to accurately represent the absence of current.
