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. Voltage input range : DC0-25 V Voltage detection range : DC0.02445 V-25 V Voltage analog resolution : 0.00489 V Output Interface : \"+ \" connected 5\/3.3V, \"-\" connected GND, \"s\" connected Arduino AD pins DC input interface : red terminal positive with VCC, negative with GND By 3P connector, connect this module with the expansion of board Arduino, not only makes it easier for you to detect voltage battery, can also use the IICLCD1602 LCD to display voltage.
