Being the first in class, MAN3420A is a compact character display module that has been designed for both industry and hobby users. The module is one of the smallest pure LED character and numeric display modules available on the market, making it a great choice for applications where space is at a premium. It utilizes 12 LEDs to display 20 characters or numbers and includes a wide array of features such as dual level voltage input, selectable character set, and multiple languages.

The MAN3420A features a single pin interface to the microcontroller, eliminating the need for complicated reset and clock circuitry. It has a wide voltage range of 2.7V to 5.5V and is able to light up even at relatively low voltages, making it ideal for battery-powered applications. Additionally, the design supports both static display and animated display, making it possible to simulate the effect of a real-life display. The module also includes a wide variety of options such as optional control pads, remote control pads, multiple languages, and various fonts.

The MAN3420A works by using a single-wire two-way communications protocol between the host microcontroller and display module. The microcontroller will first send out a command to the module, which is then acknowledged by the module. After acknowledging the command, the module will send back any data that was requested in the command. All data is sent and received through a common serial line.

In addition the MAN3420A features a wide variety of features such as brightness control, character rotation, cursor movement and font selection. The module also supports a wide range of different languages, making it easy to integrate into existing microcontroller projects.

The photo-mosaic display technology is used by the MAN3420A in order to achieve its compact size. The photo-mosaic consists of a matrix of LEDs arranged in an interlocked fashion. Each LED corresponds to a different character, making it very simple to control large numbers of icons, characters, or numbers with only a few digital pins on a microcontroller.

The MAN3420A is a great solution for applications that require a reliable, low-power, and highly-flexible display module. Its small form factor makes it ideal for space-constrained applications, while its wide range of features makes it an all-in-one solution for various projects.
