Technical summary
Description:
-Measures the voltage and current in the circuit
-Adopts the MAX471 chip, the module directly uses the detected power supply
-The minimum voltage input detected by this module is 3V
-The voltage test principle is based on the resistive voltage divider design principle, which reduces the voltage at the terminal interface input by 5 times. The analog input voltage is a maximum of 5V, so the input voltage of the voltage detection module cannot be greater than 5V x 5 = 25V (if you use a 3.3V system, the input voltage cannot be greater than 3.3V x 5 = 16.5V)
Specification:
-Size: approx. 23.8x22x14mm/0.93x0.86x0.55 inches
-VT: voltage detection pin, the detected voltage is 1/5 of the input voltage
-AT: current detection pin
-GND: connect to GND
-VOUT/VIN: VOUT = VIN
-Voltage detection range: 3-25V (operating voltage: 5V) or 3-16.5V (operating voltage: 3.3V); current detection range: 0-3A, precision: 200; current/voltage conversion ratio: 1V/A
