New. This module is used to test the current and voltage.

- Model: GY-471
- Test Voltage range: DC3 25V (Arduino work on 5V) or DC3 16.5V (work on 3.3V)
- Test Current range: DC 0 3A
- Size: 19.5 * 20.3mm
- Color: purple

1. This module can be used to test the current and voltage.
2. 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. 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).
3. 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 0.00489 Vx5 = 0.02445V.

Package Include:
1 x MAX471 Current Sensor Module
