ITEM NAME:GY-471 3A Range Current Sensor Module Professional MAX471 Module For Arduin L7F7 GY-471 3A Range Current Sensor Module Professional MAX471 Module For Arduin L7F7 Feature: This module can be used to test the current and voltage. The principle of voltage test based on principle of resistive voltage divider design, can make the red terminal connector input voltage to 5 times smaller. Analog input voltages up to 5V, the voltage detection module input voltage not greater than 5Vx5 = 25V (if using 3.3V systems, input voltage not greater than 3.3Vx5 = 16.5V). AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V / 1023), so the minimum voltage of input voltage detection module is 0.00489 Vx5 = 0.02445V. The MAX471 chip on the board used to test the consume current of the load. Specificationsï ¼Å¡ Test Voltage range: DC3 - 25V (Ard uino work on 5V) or DC3 - 16.5V (work on 3.3V) Test Current range: DC 0 - 3A Size:19.5 x 20.3mm Color: purple Material: Metal Package Contents: 1 x MAX471 Current Sensor Module 1 x pin header 1 x terminal Only the above package content, other products are not included.
