Description:
Voltage input range: DC0-25V
Voltage detection range: DC0.02445V-25V
Voltage analog resolution: 0.00489V

Introduction:
This module is based on a resistive divider principle design, make the interface terminal input voltage reduced 5 times, development board analog input voltage up to 5V, then the input voltage of the voltage detection module can not be greater than 5V × 5 = 25V (if used 3.3V system, the input voltage can not exceed 3.3Vx5 = 16.5V). Because development board AVR chips used in 10 AD, so the resolution of the analog module is 0.00489V (5V / 1023), so the voltage detection module detects a minimum input voltage of 0.00489V × 5 = 0.02445V.

Output interface:
"+" Connect to 3.3V / 5V
"-" Connect GND
"s" Connected to the Analog pin
