This is Dot Led Matrix Module incorporating MAX7219 Driver chip. By using this dot LED module in your upcoming project,  you will be able to add some great cool animation.

The individual module features 8×8 LEDs, each controlled very precisely by the MAX7219 driver to generate the color pattern you wish. The great advantage of using this is users will have control over all of the 64 LEDs by just connecting 3 output communication wires to microcontrollers like Arduino etc.

Features: 

1. Requires only 3 communication wires of MCU
2. Cascading multiple Matrix LED Module is very easy
3. Size of the display is very compact
4. The PCB features M3 holes for mounting.

Do you have battery 9V and need 5Vdc? With this small kit you can connect your battery 9V easily with 9V battery clip and get at the end both 5Vdc & 9Vdc at the same time through a standard pin header 2.54″ connector – Now you can connect to your breadboard directly.

Specifications:

• On/Off switch.
• 7805 Voltage regulator
• 9V Battery clip
• 9Vdc & 5vdc outputs
• Dimensions: 42 x 13 mm

Battery 9v is not included with this kit – you need to buy it separately (check the available options below)
