? This module is based on resistive voltage divider design principles, It is capable of reducing the voltage of the input terminal connection five times
? You can use a 5V maximum voltage on the ADC side of the module so which allows for a maximum of 25V on the input side
? If 3.3V is used, the input voltage must not exceed 16.5V
? Because AVR chips use 10 bit ADC, the maximum resolution of this module is 0
? 00489 V (5V / 1023), so the voltage detection module detects minimum input voltage is 0.00489VÁ 5 = 0.02445
? Input voltage range: DC0-25V
? Voltage detection range: DC0.02445 V - 25V
? Voltage analog resolutions: 0.00489V
? DC Input: positive terminal connected to VCC, GND negative pole
? Output interface: "+" then 5 / 3.3V, "-" then GND, "s" then the AD pin
