\n
Size: 25mm\u00d713mm\/0.98\u2033\u00d70.51\u2033(approx)<\/li>\n
This module is based on principle of resistive voltage divider design,<\/li>\n
can make the red terminal connector input voltage to 5 times smaller.\u00a0input voltages up to 5v,<\/li>\n
the voltage detection module input voltage not greater than 5Vx5=25V<\/li>\n
(if using 3.3V systems, input voltage not greater than 3.3Vx5=16.5V)<\/li>\n
\u00a0AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V\/1023),<\/li>\n
so the minimum voltage of input voltage detection module is 0.00489Vx5=0.02445V.<\/li>\n
Voltage input range : DC0-25 V<\/li>\n
Voltage detection range : DC0.02445 V-25 V<\/li>\n
Voltage analog resolution : 0.00489 V<\/li>\n
Output Interface : \u201c+ \u201d connected 5\/3.3V, \u201c-\u201d connected GND, \u201cs\u201d connected\u00a0AD pins<\/li>\n
DC input interface : red terminal positive with VCC, negative with GND<\/li>\n
By 3P connector, connect this module with the expansion of board,<\/li>\n
not only makes it easier for you to detect voltage battery,<\/li>\n
can also use the IICLCD1602 LCD to display voltage.<\/li>\n<\/ul>\n<\/div>\n<\/body>","protected":false},"excerpt":{"rendered":"
