Description: 

· This module can be used to test the current and voltage

· The principle of voltage test based on principle of resistive voltage divider design, can make the red terminal connector input voltage to 5 times smaller

· for Arduino analog input voltages up to 5 v, the voltage detection module input voltage not greater than 5Vx5=25V 
(if using 3.3V systems, input voltage not greater than 3.3Vx5=16.5V).for 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

· The MAX471 chip on the board used to test the consume current of the load

· Parameters:

· Test Voltage range: DC3 - 25V (for Arduino work on 5V) or DC3 - 16.5V (for Arduino work on 3.3V)

· Test Current range: DC0 - 3A

· PCB Size: 22*21*7mm/0.86*0.82*0.27"
