Pin 5V power supply, on-board power indicator;
The module can be measured plus or minus 30 amps, corresponding to the analog output of 185 mV / A;
There is no the detection current through, the output voltage is VCC / 2;
PCB board size: 31 (mm) x13 (mm);
Note: ACS712 Hall detection principle, when you use to avoid magnetic field impact this!
