The HDSM-531C is a type of LED display module which is often used in a wide variety of applications where digital display is necessary.

The module is composed of two sections; the first consists of two individually-addressable 8 x 8 red LED matrices which are connected by two electrical links to an array of common anode, 7-segment displays.

The HDSM-531C features a 3V/250mA regulated, common cathode drive output for each individual LED display. The module requires a 5V to 28V DC, externally supplied power supply for operation. The LEDs are mounted in a 90mm x 91mm, black ABS plastic frame.

Applications for the HDSM-531C include industrial instrumentation, scoreboards, timer/clock displays, and time/date displays. It is also popular among hobbyists and is used with microcontroller-based control systems to create customised displays. The module requires specialised software for use with embedded applications.

The HDSM-531C works on the principle of multiplexing, a technique which enables the display to be driven by a single microcontroller. This technique is used to reduce the number of I/O pins and power devices required, while still providing a reasonable refresh rate and light intensity.

Multiplexing involves the use of two sections; the first, the LED array, is divided into columns and rows, while the second, a data driver, is divided into digits. Each row and column is then connected to single output of the data driver, enabling the LED array to be driven using only a single set of I/O pins. As data is written to the data driver, it is converted into an analog signal and routed to the appropriate row or column. When the row or column is enabled, the LEDs in that row or column are illuminated, creating a character or graphic.

The HDSM-531C LED display module requires minimal external components for operation, making it ideal for applications where cost and space are a factor. It is capable of displaying either 2D or 3D graphics and is easy to use with embedded systems control applications. The module also offers a high degree of contrast and a wide viewing angle. This makes it the perfect choice for a wide variety of applications.
