2. Works Perfectly With for Any Circuitpython Or for Compatible Microcontroller As Well As Single Board Computers Such As for . 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!), 0.1% 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 Register It As A Short Circuit!) 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 1% Accuracy Over An Impressive Voltage, Current, And Temperature Range, While Transmitting Data In An Easy-To-Use Format Over . 4. In High-Side Configuration, The Bus Voltage Measurement And Power Calculation Can Be Retrieved Accurately, But Advanced Hackers Who Want To Measure The Bus Voltage In Low-Side Configuration Need To Cut The Jumper Connecting V+ And Vbus And Connect The Vbus Pin To The Voltage Bus., Weight: 0.00440924524 pounds, Manufacturer: NONDK
