Technical Details

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
