LED indicators are widely used in various electronic circuits. They are typically used in consumer electronic products, household appliances, safety equipment, and industrial control devices. In particular, Discrete LED indicators, generally those with one or two colors, are used to indicate simple functions or states. Few components feature a higher density of LEDs as the WP7104GD Discrete LED Indicator, with its densely packed 64-LED array in a 1” x 0.66” footprint.

WP7104GD Overview

The WP7104GD Discrete LED Indicator features 64 individual 1cmx1cm LEDs each of which can be independently driven with an onboard programmable microcontroller. This makes it an ideal solution for applications that require high-density LED indicators with unmatched reliability. The narrow but tall size allows the WP7104GD to fit in tight spaces. The indicator has an operating temperature from –20°C to 85°C, and can dissipate up to 60 mW at 9V/50mA.

The WP7104GD is a great solution for projects requiring a high density LED indicator in a space-saving format. It is available in both through-hole and surface-mount versions, and the shape ensures that the LED board fits into tight spaces.

WP7104GD Application Field

The WP7104GD can be used in a variety of applications, including status indication, simplified computer control and process monitoring. Its extremely high LED count makes the WP7104GD suitable for applications that require more than a few LEDs for indication such as providing indication for entire systems or multiple pieces of equipment. The WP7104GD makes it possible to use a single indicator to provide indication for multiple pieces of equipment. The LED array can be used as simple indicators as well, such as simple indicators for channel selection on audio and video equipment or process control.

Additionally, the WP7104GD can be used in security systems where different light combinations can be used to indicate whether an alarm is active or inactive. The indicator can also be used in industrial applications to display multiple running states, such as in conveyor belt systems or material handling equipment. The WP7104GD can also be used to indicate resource levels, such as in device operation or fluid levels.

WP7104GD Working Principle

The WP7104GD consists of an MCU module and a 8x8 single-color LED display module. The MCU module, designed for a 9V supply voltage and 16MHz frequency, controls the LED display module by decoding the serial input data and then driving the 8x8 red LEDs. The MCU module also contains a 64-bit security code that allows the user to easily configure the functionality of the indicator.

The WP7104GD features an active-low switch that can be used to enter programming mode. The 64-LED array consists of 8 rows and 8 columns, each row has 8 LEDs connected in series; the columns are connected in parallel. When a logic 0 is applied to a row, the corresponding 8 LEDs will be lit. When a logic 1 is applied, the LEDs of the corresponding row will be turned off. By applying logic 0 or logic 1 to different rows, different patterns and colors can be displayed.

The WP7104GD can also be used in applications that require multiple colors. For example, by applying different voltages to the 8x8 LED array, various colors can be displayed. The WP7104GD can also be used for LED animation, as well as for displaying simple messages or symbols.

Conclusion

The WP7104GD Discrete LED Indicator is a great solution for applications that require high-density LED indicators in a space-saving format. It is highly reliable, and can be used in applications that require more than a few LEDs for indication. The WP7104GD can be used in status indication, simplified control, process monitoring, security systems, industrial applications and more. The active-low switch allows for easy configuration, and the array is designed for different colors. The WP7104GD is a great choice for any application that requires an ultra-dense LED indicator.
