GY-471 3A Range Current Sensor Module Professional MAX471 Module For Arduin L7F7

GY-471 3A Range Current Sensor Module

• GY-471 3A Range Current Sensor Module is suitable for measuring both current and voltage.
• By utilizing the resistive voltage divider design, the voltage test principle reduces the red terminal connector’s input voltage by a factor of 5.
• The analog input voltages can reach a maximum of 5V, and for the voltage detection module, it should not exceed 25V (or 16.5V if using a 3.3V system).
• The 10-bit AD of AVR chips enables this module to simulate a resolution of 0.00489V (5V / 1023). Therefore, the minimum voltage for the input voltage detection module is calculated as 0.02445V (0.00489V x 5).
• The board features a MAX471 chip, which measures the load’s current consumption during testing.
