SparkFun 7-Segment Serial Display - Red
A 4-digit 7-segment display with a built-in ATmega328 microcontroller, controllable via Serial TTL, SPI, or I²C — no complex wiring or multiplexing required. Each segment, decimal point, apostrophe, and colon can be individually controlled. The ATmega328 comes pre-loaded with the Arduino bootloader, so the board can also be programmed for stand-alone operation via the onboard FTDI header.
Power and I²C pins are on the sides of the board, allowing multiple displays to be daisy-chained for longer digit strings. Mounting holes are included for standoff installation.
Key Features
- Triple Interface – Serial TTL, SPI, or I²C communication
- 4-Digit Alphanumeric – Displays numbers, most letters, and special characters in red
- Individual Segment Control – Control each segment, decimal point, apostrophe, and colon independently
- Adjustable Brightness – Software-selectable, saved to non-volatile memory
- Selectable Baud Rate – Configurable and retained in non-volatile memory
- Arduino Programmable – ATmega328 with Arduino bootloader, FTDI header for programming
- Chainable – Side-mounted I²C pins for daisy-chaining multiple displays
- Dimensions: 41 × 23mm
Ideal For
- Displaying sensor readings, counters, or clocks
- Arduino and microcontroller projects needing numeric output
- Instrument panels and status displays
- Stand-alone timed or triggered display applications
