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!<\/p>\n\n
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 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.<\/p>\n\n
We'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. A pair of USB 2.0 A to C Cables<\/a> will allow you to connect the input to your USB port or power supply and the output to your board. You might find our BNC to Alligator Cable<\/a> useful for connecting to your oscilloscope. Our Banana to Alligator Coax Cable<\/a> is perfect for connecting your multimeter.<\/p>\n\n We do not plan to regularly produce SparkX products so get them while they\u2019re hot!<\/p>\n\n Features:<\/strong><\/p>\n\n Documents:<\/strong><\/p>\n\n\n
