LED matrix backpacks simplify the wiring of 4-digit 7-segment displays, offering an effortless way to add numeric displays. Using driver chips, they handle multiplexing with a built-in clock and constant-current drivers for consistent brightness via a simple I2C interface.Specifications include 1/16 step display dimming and address-selection jumpers, allowing up to eight displays on a single I2C bus. Embrace versatility with adaptable power settings from 3.3V to 5.0V. This ensures bright LED outputs, powered appropriately even when utilizing 3V logic.The product kit comprises a pre-assembled LED backpack, an ultra-bright yellow 1.2" four-digit display, and a 5-pin header. A minimal soldering effort makes it easy to set up. Comprehensive tutorials and custom libraries enable display control with Arduino or Raspberry Pi in under 30 minutes. https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2025-10-30 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2025-11-01 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2025-11-07 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2025-11-10 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2025-11-25 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2025-11-28 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2025-12-03 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2025-12-06 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2025-12-08 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2025-12-14 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2025-12-19 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2026-01-10 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2026-01-23 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2026-01-26 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2026-01-31 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2026-02-03 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2026-02-22 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2026-02-27 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2026-03-03 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2026-03-06 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2026-03-15 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2026-03-22 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2026-03-30 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2026-04-01 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2026-04-13 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2026-04-20 https://elecena.pl/product/29464093/adafruit-1-2-4-digit-7-segment-display-w-i2c-backpack-yellow 2026-04-22
