These are often used by RC hobbyists for keeping track of batteries but we thought it would be great on a breadboard or enclosure. This is the 2-wire version of the volt meter, two wires are used to power it and measure at the same time. We also have a 3-wire version that measure a wider range of voltages.\u003cbr\u003e\u003cbr\u003eSimply connect the red wire to the positive supply, and black to negative ground. The display has a microcontroller that will read the voltage, compare it to a stable reference and display the voltage with 0.1V precision on a 3-digit 7-segment display. It works from 3.2V up to 30V so it will be good for nearly any electronic project! The meter draws 3-4mA to power the microcontroller and display. This particular LED display is a nice vivid green, which we found very readable. Mounting tabs make this module easy to attach to any box or plate.\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cp\u003eDimensions:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePCB (with mounting holes): 33mm x 15mm \/ 1.3\" x 0.6\"\u003c\/li\u003e\n\u003cli\u003eDisplay: 23mm x 14mm \/ 0.9\" x 0.6\"0\u003c\/li\u003e\n\u003cli\u003eCombined Depth: 10mm \/ 0.4\"\u003c\/li\u003e\n\u003cli\u003eWeight: 4.8g\u003c\/li\u003e\n\u003cli\u003eMounting hole diameter: ~1.9mm\u003c\/li\u003e\n\u003cli\u003eCenter-to-center distance: 28mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003ePower specifications:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e3.2V to 30V DC measurements\u003c\/li\u003e\n\u003cli\u003e0.1V precision\u003c\/li\u003e\n\u003cli\u003e3-4mA draw\u003c\/li\u003e\n\u003cli\u003eGreen LED display\u003c\/li\u003e\n\u003cli\u003eUse with positive voltages only!\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul id=\"product-files\"\u003e \u003c\/ul\u003e \u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":52217317818656,"sku":"rdg1787257608072","price":5.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0946\/3231\/3120\/files\/mini-2-wire-volt-meter-32---30-vdc_1.jpg?v=1787257613","url":"https:\/\/www.elmwoodbasket.shop\/products\/mini-2-wire-volt-meter-32-30-vdc","provider":"My Store","version":"1.0","type":"link"}
