XMMR07A

Display Modules - LED Dot Matrix and Cluster

The XMMR07A is a display module based around a Red and Yellow 5x7 dot matrix cluster. The module is designed to be used in display applications such as state change indicators, and warning lamps. It has a small footprint and is easy to implement into an existing system.

The module is made up of two individual 5x7 grids - one red and one yellow. Each grid contains 49 LEDs and is driven by two independent current drivers. This allows for selection of individual dots or zones within the matrix, allowing for various pattern and color displays. The modules come with adjustable current settings and have a wide input voltage range of 3.3V to 15V.

The XMMR07A can be used for various types of applications. It can be used to provide a visual indication of a states, such as in control systems, to alert user to certain conditions such as alarms. The module can be used in displays, such as scoreboards or game consoles, or to create various patterns or animations. The module can also be used with text-based messages, or other screens with dynamic content.

Working Principle

The working principle of the XMMR07A is based around current driving LEDs. Each LED is connected to two 8-bit current drivers, which control the brightness of the LED. With the current drivers, the individual dots or zones of the matrix can be selected and their brightness can be adjusted. The LEDs are connected to their respective current drivers through two sets of pins, the red and the yellow. These pins are connected to the microcontroller and the current drivers.

The current is provided by the power supply, regulated through the regulator and then supplied to the LED. The microcontroller then controls the current flow, to achieve the desired brightness. The LED is dimmed or brightened based on the amount of current supplied to it, which is why it is possible to set the brightness of each LED in the matrix or zone. Additionally, the current drivers allow for the selection of various patterns or animations to be formed.

Conclusion

The XMMR07A module is a great tool for creating various displays for applications such as control systems and animation. It has a small footprint and a wide input voltage range which makes it very easy to integrate into existing systems. With the adjustable current settings, it is possible to select individual dots or zones and create various patterns or animations. The XMMR07A is a great option for creating visual displays and is sure to meet any needs.
