Product Parameter:
1. Size:19.5*20.3mm
2. Test Voltage range: DC 3-25V (Arduino work on 5V) or DC3-16.5V (work on 3.3V)
3. Test Current range: DC 0-3A
4. Chip: MAX471

Description :
1. The principle of voltage test is based on principle of resistive voltage divider design,
   it can make the red terminal connector input voltage to 5 times smaller, analog input voltage will up to 5V,
   the voltage detection module input voltage is not greater than 5Vx5=25V (if using 3.3V systems, input voltage will not be greater than 3.3Vx5=16.5V).
2. 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.
3. The MAX471 chip on the board is used to test the consume current of the load.
4. This module can be used to test the current and voltage.
