HiLetgo 2pcs MAX471 3A Current Sensor Module Consume Current Detection Module DC 0-3A

• MAX471 3A Current Sensor Module
• Current and voltage testing
• Resistive voltage divider design
• MAX471 chip on the board
• Test Current range: DC0 - 3A

<b>Description:</b> <br> This module can be used to test the current and voltage<br> 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 <br> For Arduino analog input voltages up to 5 v, 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).<br> for Arduino 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 0.00489Vx5=0.02445V<br> The MAX471 chip on the board used to test the consume current of the load.<br> <b>Parameters:</b><br> Test Voltage range: DC3 - 25V (for Arduino work on 5V) or DC3 - 16.5V (for Arduino work on 3.3V)<br> Test Current range: DC0 - 3A<br> <b>Package included:</b><br> 1* MAX471 3A Range Current Sensor Module Current Detection Module NEW<br>
