{"product_id":"sparkfun-usb-current-sensor","title":"SparkFun USB Current Sensor","description":"\u003cp\u003eDo 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!\u003c\/p\u003e \u003cp\u003eThe 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 resistor. Together these produce an output of 1 Volt per Amp. If your board is drawing 100mA, you will see an output of 100mV. The maximum current it can measure is 2 Amps and we've included a 2A resettable fuse for added protection.\u003c\/p\u003e \u003cp\u003eWe've provided both 0.1\" breakout pads and Gator pads, to make it easy to connect up your multimeter or oscilloscope. Feed power in via the USB-C socket, and provide power to your board via the USB-A socket.
