MAX471 Voltage Test Module Features
MAX471 Voltage Test Module is used to test the current and voltage in the circuit. The red terminal can make the input voltage 5 times smaller. Since Arduino analog input voltages are up to 5v, the voltage detection module input voltage should not be greater than 5Vx5 = 25V (if 3.3V systems are used, the input voltage should not be greater than 3.3Vx5 = 16.5V).
Module The MAX471 chip on it is used to test the consumed current of the load.
- Test Voltage range: DC3 - 25V (Arduino works on 5V) or DC3 - 16.5V (for Arduino Works on 3.3V)
- Test Current range: DC 0 - 3A, Precision 2%, current and voltage conversion rate is 1V/A.
