{"title":"SparkFun 7-Segment Serial Display - White","handle":"sparkfun-7-segment-serial-display-white","url":"/products/sparkfun-7-segment-serial-display-white","description":"A smart 4-digit 7-segment display that combines a classic white LED display with an onboard ATmega328 microcontroller. Instead of wiring up dozens of pins, you control the entire display over Serial TTL, SPI, or I2C — using just a few connections.\n\nThe ATmega328 comes pre-loaded with the Arduino bootloader, so you can reprogram the display for stand-alone operation via the onboard FTDI header. The board features side-mounted power and I2C pins for daisy-chaining multiple displays, plus mounting holes for clean installation.\n\nKey Features\n\n\n3 Communication Interfaces – Serial TTL, SPI, or I2C — choose what suits your project\n\nIndividual Segment Control – Full control of every segment, decimal point, apostrophe, and colon\n\nAdjustable Brightness – Configurable via serial commands, saved to non-volatile memory\n\nSelectable Baud Rate – Retained in non-volatile memory between power cycles\n\nDaisy-Chainable – Side-mounted I2C and power pins for linking multiple displays\n\nArduino Bootloader – Reprogrammable for custom stand-alone applications\n\nMounting Holes – For clean, secure installation on standoffs\n\nCompact Size – 41 × 23mm (1.6\" × 0.9\")\n\n\nDisplay Capabilities\n\nNumbers (0–9)\nMost letters of the alphabet\nSpecial characters\nDecimal points, apostrophe, and colon\n\n\nIdeal For\n\nClocks, timers, and countdowns\nSensor readouts (temperature, voltage, speed)\nScore displays and dashboards\nAny project needing a simple numeric display\n\n\nPackage Contents\n\n1× SparkFun 7-Segment Serial Display (White)\n\n\nResources\n\nHookup Guide\nDatasheet\nSchematic (PDF)\nGitHub Repository\nEagle Files\nArduino Add-On\n","vendor":"SparkFun","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":11326,"title":"Default Title","sku":"SF-COM-11629","price":36.34,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
