Occupy few MCU ports, ability of scrolling display of a few hundred words*-screen series, text scrolling display, can build electronic billboards

Features:

1, Use high-quality bright LED DOT-matrix block

2, Optimized circuit design, with brightness uniformity

3, Standard interface that can be expanded in a variety of development boards

4, Multi-screen connectivity is available

5, ***-line scan, **5 numbers

6, Applicable to a variety of platforms including Arduino / AVR / ARM

Able to support direct multi-screen connection, it can achieve rolling display by cascading the LED *6**6 Matrix directly like putting up building block only with 5 pin jumper wire.

How to achieve the cascading and achieve rolling display?

The answer is that you just need two 5 pin jumper cables used to link one LED brick to another, then you have achieve rolling display, because our circuit have solved all the query at the back stage. So this allow that you can cascade as more piece as you can.

However it occupy few MCU interface and own the ability of scrolling display of hundreds of words.
Support text, cartoon, etc scrolling display, so you can build electronic billboards and any other application you need easily.

The most important is that: You can achieve what you need and what you imagine in your mind about Matrix LED.

Now I am telling you something of LED Array Screen. I will show you an DIY experiment.
Tools used:

1. Arduino Duemilanove with ATmega **8
2. Arduino Sensor shield V4.0
3. *-pin jumper wire
4. *-pin jumper wire
5. Wrobot *6X*6 LED Array Screen

Connect digital pin 4, 5, 6, 7 to pin OIA, OIB, OIC, OID of LED screen, which choose the row. Connect digital pin 8, 9, *0 to pin SER, SCK, RCKof screen, which the data of a row. Connect GND and VCC to power.

Extension connection is very easy too. Connect pin on the OUT side of one board to the pin with the same name on the IN side of the next board.

In fact, you can assemble a screen of ant size you want(times of *6), large square screen or long screen. And you can program it to display anything you want.
