The module uses a TM1651 LED driver chip to drive the individual LED segments, which can be controlled by using only 2 GPIO pins of a microcontroller (such as an Arduino® compatible board). It should be noted that some of the LED-segments are wired together, resulting in 8 different controllable states of the LED bar graph.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003edrive a 10-segment blue LED bar graph\u003c\/li\u003e\n\u003cli\u003econtrollable by 2 GPIO pins\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003esupply voltage: 3,3 - 5 V DC\u003c\/li\u003e\n\u003cli\u003ecolor: blue\u003c\/li\u003e\n\u003cli\u003edriver chip : TM1651\u003c\/li\u003e\n\u003cli\u003enumber of LED segments: 10\u003c\/li\u003e\n\u003cli\u003enumber of level indicators: 8\u003c\/li\u003e\n\u003cli\u003einterface: 2 wire serial\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Velleman","offers":[{"title":"Default Title","offer_id":39363656122451,"sku":"WPI471","price":8.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/wpi471.jpg?v=1623854469","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/bar-graph-display-module-2-pcs","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
