16 * 16 dot matrix description:
1. Supply voltage: DC 5V
2. Principle: Each row consists of 4~16 decoders by two 74HC138 + transistor drive; each column cascade driven by the two 74HC59; LED in cross point will light on if row outputs high level and column outputs low level
3. Compatible with LCD12864 interfaces， plug and play
4. Offers 51 microcontroller and Arduino examples
