- Working out of the box. - Simply connect 5V to the Jack and it can works. (I connect a USB cable with a Jack on the other side and power it from my xbox360)
- Really bright when at Max. - Digit are Big, - Not enough instruction to change the built-in code. - Need a external programmer device to change the Chinese code. - the device have place for ... Read more
Cheap, hackeable and cool.
I can make some fun stuff only adding an accelerometer and replacing the atmega8 by an Atmega 328 with Arduino bootloader.
You can see a cool hack at http://www.radikaldesig.com/2012/08/22/sistema-de-particulas-en-matriz-led-con-acelerometro/ Could include a 5v Regulator to prevent possible over voltage from people without ... Read more
Works. Arduino drivers available, but layout of matrix differs from sure 3208 matrix and minor modifications are required. Performs well and is relative cheap. Build-in application (clock) is useless, since oscillator quality is not good (time differs several seconds in a day). Be careful with voltage (5v) since board has no regulators and over voltage ...

Nice module with a nice LED driver. Comes with an ATmega8 just waiting to be programmed by you. Includes an ISP header. There are spots on the board to add several components like a temperature sensor or a battery buffered real time clock. Three buttons. The original clock software is a matter of taste, but the date display with chinese symbols is a ... Read more
Out of the package, it behaves as a clock/calandar. When powered up with a 5VDC source, the unit will display the time then shortly afterward scroll the date. The time and date can be set by pressing the top button to go into settings mode, then pressing one of the lower two buttons to raise and lower the setting. When in standard display mode, the ...
