Instead\r\nof struggling with a multimeter, you can just use the handy INA169 chip on\r\nthis breakout to both measure both the DC current draw and have a handy analog\r\noutput that is with respect to ground. The analog output makes this an ideal\r\nbreakout for feedback-loop control. Most current-measuring devices such as our\r\ncurrent panel meter are only good for low side measuring. That means that\r\nunless you want to get a battery involved, you have to stick the measurement\r\nresistor between the target ground and true ground. This can cause problems\r\nwith circuits since electronics tend to not like it when the ground references\r\nchange and move with varying current draw. This chip is much smarter - it can\r\nhandle high side current measuring, up to +60VDC! A precision amplifier\r\nmeasures the voltage across the 0.1 ohm, 1% sense resistor. The resistor is\r\nrated for 2W continuous so you can measure up to +5A continuous. The output is\r\na current that is drawn through the on-board 10K resistor so that the output\r\nvoltage is 1V per Amp. So for 2A draw, the output will be 2V. You can change\r\nout the load resistor to be larger or smaller by cutting the traces next to it\r\nand soldering a thru hole resistor over. If you solder in a 20K resistor\r\nyou'll get 2V per Amp, with a 5K resistor, 0.5V per Amp\u003c\/p\u003e \r\n\r\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\r\n  \u003cul class=\"a\"\u003e\r\n         \u003cli\u003eMeasure both the DC current draw and have a handy analog output that is with respect to ground\u003c\/li\u003e\r\n         \u003cli\u003eIdeal breakout for feedback-loop control\u003c\/li\u003e\r\n         \u003cli\u003eRated for 2W continuous so you can measure up to +5A continuous\u003c\/li\u003e\r\n         \u003cli\u003e0.1 ohm, 1% 2W current sense resistor\u003c\/li\u003e\r\n  \u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":44154580697268,"sku":"B00NAY3FSM","price":134.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/9906\/1172\/files\/B00NAY3FSM.jpg?v=1775787868","url":"https:\/\/auspowers.com\/products\/adafruit-ina169-analog-dc-current-sensor-breakout-60v-5a-max","provider":"AusPower Australia","version":"1.0","type":"link"}
