Buy LED matrix shield kit - DISCONTINUED

Check out the newest LED matrix shield here.


Updated Sep 1, 2011
As of today, this kit is no longer offered, since I ran out of LED matrices. If you are still interested in the PCBs (because you already have a compatible LED matrix, for example, or maybe you just want to adapt a similar one), drop me a line.


Updated Feb 16/2010

The 40-pin female header, meant as a socket for the LED matrix, was replaced with two 12-pin machined female headers (see this posting), a much better solution. In the same time, since these headers are shorter, the LED matrix will be closer to the board, touching on the ICs underneath. Therefore, I eliminated the 3 IC sockets, since they do not make sense anymore.

Also, the 220 ohms resistor was replaced with a 110 ohms.

Here you can order a kit of the LED matrix shield for Arduino.
Paired with Wiseduino, which has on board RTC (real time clock) DS1307 and EEPROM 24LC256, it makes the Wise Clock.
(Please check out The Shoppe for more kits.)

The LED matrix shield kit includes the following components:

• PCB, black;
• 8x8 bi-color (red + green) LED matrix, medium size (47 x 47 mm);
• 2 x 74HC595 shift registers with 2 x 16 pin sockets;
• ULN2803A with 18 pin socket;
• 17 x 110 ohm resistor;
• 2 x micro push button;
• 220 ohm resistor;
• 10K resistor;
• 2 x 100nF capacitor;
• 40 pin female header; 2 x 12-pin machined round female header;
• 40 pin male header;
• infrared receiver.
