Quad 7-Segment Blue LED Display (with Colon), TTL or SPI Control US$12.95

COM-09765
Quad 7-Segment Blue LED Display (with Colon), TTL or SPI Control


This 7-Segment Serial Display board turns the 13 pins necessary to control a 4-digit 7-segment display into just one or three. The display will give you full control of all digits, decimal points, the colon and the apostrophe. At the heart of the display is an ATmega328 which controls all the serial communications and the 4-digit 7-segment display through an easy-to-use API.

The Serial 7-Segment Display can be controlled in either of two ways: Serial TTL communication (one wire) or SPI serial communication (three wires). Regardless of which method you use to communicate with the display, the display is controlled with 4-byte packets and special 2-byte commands.

Input and power pins are on top of the display, allowing you to place multiple displays side by side to create a longer string of digits. Note however that the board does not have mounting holes, so you may need to find a creative way to secure this in any final product.

4-Digit 7-Segment Serial LED Board Features

  • 4-digit blue alphanumeric display with serial (1-pin) or SPI (3-pin) interface
  • Can display numbers, most letters, and a few special characters
  • Individual control of decimal points, apostrophe, and colon
  • Selectable baud rate (2400 to 57600 bps)
  • Selectable brightness
  • Baud rate and brightness values retained in non-volatile memory
  • Individual segment control for each digit
