Q2: How much current can it measure directly?A: Up to 10A directly, and up to 100A with the external shunt. Q3: Is the 100A shunt included?A: Yes, the package includes a 100A/75mV shunt. Q4: Does it work with AC?A: No, it is designed for DC voltage and current measurement only. Q5: What size is the display?A: 0.28-inch dual LED (red for voltage, blue for current). Q6: Can I use it with Arduino?A: Yes, but Arduino will only read values separately if additional sensors are used. This module itself directly displays the readings. Q7: Does it require calibration?A: Generally pre-calibrated, but slight adjustments may be required for precision. Q8: What is the operating voltage for the module itself?A: 4.5V – 30V DC. Q9: Can it be used for solar panel monitoring?A: Yes, commonly used in solar and renewable energy monitoring projects. Q10: Is it beginner-friendly?A: Yes, very easy to use and install in DIY or professional projects.
