- Size: 19.5 * 20.3mm 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 inp voltage to 5 times smaller. Analog inp 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). 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.
- The MAX471 chip on the board used to test the consume current of the load.
- Paramenter: Test Voltage range: DC3 - 25V (Ard uino work on 5V) or DC3 - 16.5V (work on 3.3V) Test Current range: DC 0 - 3A
