Fangrui Product Details 1. Not Only Can It Do The Work Of Two Multimeters, But It Can Do It With Amazing Accuracy And Flexibility. With It You Can Measure High Or Low Side Dc Current, Bus Voltage And Have It Automatically Calculate The Power. It Does This With Better Than Accuracy Over An Impressive Voltage, Current, And Temperature Range, While Mitting Data In An Easy-to-use Format Over I2c. 2. Works Perfectly With For Any Circuitpython Or For Arduino Compatible Microcontroller As Well As Single Board Computers Such As For Raspberry Pi. It Is Compatible With 3v Or 5v Logic And Can Measure Bus Voltages Up To +36vdc. Not Suitable For Ac Voltage. 3. The Voltage Across The Integrated 2 Milliohm (0.002 Ohm!), 0. Shunt Resistor Is Measured By An Internal 16-bit Adc, Allowing An Impressive Current Range To Be Measured With 1.5 Ma Resolution. (the Resistance Of The Resistor Is So Low That Some Multimeters Will Register It As A Short Circuit!) 4. In High-side Configuration, The Bus Voltage Measurement And Power Calculation Can Be
