LED modules have become a ubiquitous feature in a variety of applications due to their bright, programmable, and energy efficient nature. Thanks to their ability to display various kinds of information to the user, they are becoming a preferred device in applications ranging from digital clocks to industrial control systems. One of the most widely used types of LED modules is the SA23-12EWA, a character and numeric display module used to display text and numerical data.

The SA23-12EWA is a programmable, red LED module with a 12-character display. It is designed to work with various microcontrollers and has a two-wire serial interface, allowing data to be sent to the module from an external microcontroller. Each character is composed of 6x8 dots and can be programmed to display any combination of text and numbers with a variety of display functions and effects.

The SA23-12EWA module is typically used in applications where the display of small amounts of text or numerical data is needed. Popular applications include digital clocks, temperature displays, and scoreboards; it is also useful for industrial control systems, displays in vehicles, and educational monitors.

The module is powered by a 5v DC voltage which is supplied via the two-wire serial interface. The module also has a clock pin which is used to synchronize data transfer with an external microcontroller. Additionally, the module is equipped with a reset pin which is used to reset the module’s internal memory and clear all text from the display.

The working principle of the SA23-12EWA module is relatively simple. Data is sent from an external microcontroller to the module via the two-wire serial interface with the clock pin used to synchronize the data transfer between the two devices. The data is then processed by the module’s internal processor and displayed on the 12-character display. The module is also equipped with various display functions and effects which can be used to control the way in which the data is displayed.

In summary, the SA23-12EWA is a 12-character red LED module which is used in applications where the display of small amounts of text and numerical data is required. It is powered by a 5v DC voltage and is designed to work with various microcontrollers via a two-wire serial interface. Its working principle is relatively straightforward, allowing data to be transferred and displayed on the 12-character display using display functions and effects.
