1. Current sensor chip: ACS712ELC-30A;
2. Stick 5V control supply, onboard control pointer;
3. The module can be estimated give or take 30 amps, relating to the simple yield 66mV/A;
4. There is no identification current through, the yield voltage is VCC/2;
5. PCB board estimate: 31 (mm) x13 (mm);
Note: ACS712 Hall identification rule, when you use to stay away from attractive field affect this!
