Sparkfun Item #: SPX-18016 -

Do you want to be able to measure what current your board is drawing in real time? Maybe it is a board that draws short bursts of current? Or maybe you want to investigate what in-rush current your board draws? If so, this is the product for you! The TI INA290 is an ultra-precise current sense amplifier that can measure voltage drops across shunt resistors over a wide common-mode range. The INA290A1 on our board has a gain of 20 Volts per Volt and we measure the current using a 0.05 Ohm shunt...
