개요

  • 본 제품은 7x5 초록 LED 매트릭스 2개를 장착한 제품입니다.
  • LED 매트릭스는 8비트 serial-in, parallel-out shift register에 의해 동작됩니다.
  • 7x5 LED 매트릭스는 ASCII 문자를 디스플레이하는 표준 해상도로 본 제품은 두개의 문자를 디스플레이할 수 있습니다.
  • 타켓 MCU와는 SPI인터페이스를 통해 통신하며, 3.3V/5V 시스템과 사용이 가능합니다.

특징

  • How it works

    7x5 is a standard resolution for displaying ASCII characters, so 7x10 click is essentially a dual character display capable of showing letters in more readable typefaces compared to a 14-segment display.

    The dot matrix can also show scrolling text, thus fitting longer messages in small space. The pair of 8-bit SIPO shift registers drive the display. The current amplification necessary for driving the LEDs is performed by a Darlington Transistor array while a Johnson counter performs the necessary LED multiplex.
