The LDS-AA104RI is a large digit display module that features a seven segment red LED display with a center decimal point. This device is both aesthetically pleasing and cost effective. It is well suited for applications such as instrumentation, counters, clocks and many more.

The LDS-AA104RI makes use of a high bright red LED display. The seven segment design makes it easy to read at a glance, as the decimal point can easily be seen in the center of the display. The display runs at an efficient 30V power supply and is able to draw a minimum of 1000 mAh of current.

The LDS-AA104RI utilizes common anode operation, which means that the ground lead and the anode terminals are interchangeable. The display is compatible with both CMOS and TTL input and can be connected directly to a microcontroller. This eliminates the need for complex decoder, amplifier and multiplexer circuitry.

The LDS-AA104RI is also available with a range of output interfaces, including SPI, I2C, and GPIO. By default, the module comes with 8 LEDs, however, it can be configured to display up to 10 LEDs with different colors. This flexibility makes the LDS-AA104RI an ideal choice for a wide range of applications.

The LDS-AA104RI uses the concept of multiplexing to control the LEDs. Multiplexing is the technique of sending data to multiple locations in a single cycle. This is done by connecting each digit to a common pin, sometimes referred to as the multiplexer line. When the multiplexer is energized, the digits connected to it will turn ON and then OFF in rapid succession, allowing all digits to be lit up at the same time.

The working principle of the LDS-AA104RI is relatively simple. First, the common anode and the segment anodes are connected to the microcontroller. This connection allows the microcontroller to control the LED display. When a command is sent from the microcontroller, each segment is driven in turn to a specific time period, creating the desired multiplexing effect.

In conclusion, the LDS-AA104RI makes an ideal choice for a wide range of applications. Its ability to run at low power makes it a cost-effective solution, while its multiplexing display capability makes it a great choice for applications such as instrumentation or counters. With its compact and aesthetically pleasing design, the LDS-AA104RI is the perfect choice for any embedded application.
