LED Display Module                  DEMO Video

LEDs are flat panel displays that emit visible light when an electric current passes through the light-emitting diodes.

LED displays are brighter and visible from a greater distance, which makes them optimum for sunlight readable application. Also, it offers a wider viewing angle up-to 178 Degree (Horizontal & Vertical).

One major challenge to drive the LED display is higher numbers of MCU (Microcontroller) I/O pins required, which makes it difficult to use it with MCU that have lower number of pins such as PIC12F.  



Bolymin  LED Display Module

Bolymin LED Display Module consists of LED Display, PCB, IC and it is connected through the SPI interface.

For example, the following 4-digit seven-segment LED module features a serial interface that requires only 3 I/O pins of a microcontroller and provides full control of all digits and decimal points.
