BIG 7-SEG R Click Board™

Product Code: MIKROE-2269

The BIG 7-Seg R Click Board™ is what you need if you want to add a seven-segment LED display to your project. This Click Board™ features an SC10-21SRWA seven-segment display. Communication between the MCU and the SC10-21SRWA display is established via serial-IN, parallel-OUT shift register 74HC595 IC. The BIG 7-Seg R Click Board™ runs on either 3.3V of 5V power supply and communicates with the target MCU over an SPI interface. Display The BIG 7-Seg R Click Board™ displays letters, numbers and symbols in highly readable form. It can be used in any simple interface and combined with other Click Board™s. The color of the displayed character is red, as the R in the name of the Click Board™ states. Light Intensity The light intensity on the display is controlled via the PWM pin on the board. Applications Adding a seven-segment LED display to your device with SPI interface.
