{"title":"Red 7-segment clock display - 0.56 digit height","handle":"red-7-segment-clock-display-0-56-digit-height","url":"/products/red-7-segment-clock-display-0-56-digit-height","description":"A red 4-digit 7-segment clock display with 0.56″ (14.2 mm) digit height. Each digit includes a decimal point, plus a centre colon for time-based displays. Bright at 18 mcd, these displays are easy to read and can be dimmed by reducing drive current to save power.\n\nThis is a raw multiplexed common-cathode display — it requires external driver circuitry such as a shift register (e.g. 74HC595) or dedicated LED driver. You'll need 8 microcontroller pins or a shift register to control the anodes (~15 mA each), and NPN transistors or a high-power shift register to sink up to ~160 mA per digit on the cathode side.\n\nKey Features\n\n\n4-Digit 7-Segment Display – Plus decimal points and centre colon\n\n0.56″ Digit Height – Clear, readable digits\n\n18 mcd Brightness – Bright red LEDs, adjustable by varying drive current\n\nCommon Cathode, Multiplexed – Standard configuration for driver ICs and shift registers\n\n\nSpecifications\n\n\nDigit Height – 0.56″ (14.2 mm)\n\nColour – Red\n\nBrightness – 18 mcd\n\nMax Current per Segment – 20 mA\n\nConfiguration – Common cathode, multiplexed\n\nSegments – 7 segments + decimal point per digit, plus centre colon\n\n\nIdeal For\n\nClocks and timers\nCounters and scoreboards\nInstrument readouts\nArduino and microcontroller display projects\n\n\nPackage Contents\n\n1× Red 4-Digit 7-Segment Clock Display (0.56″)\n\n\n\nNote: This is the raw display only — no driver or backpack is included. External driver circuitry is required.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":14086,"title":"Default Title","sku":"AF-865","price":8.72,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":103,"option1":"Default Title"}]}
