Raspberry Pi Matrix Module Model B / B+ Dot Lattice LED for Arduino Developer ( $7.64 )

Raspberry Pi Matrix Module Model B / B+ Dot Lattice LED for Arduino Developer

Supports Raspberry Pi model B/B+Driver : MAX7219Matrix type : 8 × 8 common cathode LEDs Interface:Note:1. To use LED lattice screen on the raspberry pie will have trouble. Because the number of IO raspberries pie is limited, if every IO control an LED, it can only control about 35 LED at most.2. By using special LED constant current control chip, basically take up raspberries pie SPI interface can control 64 LED lights. In this way, it is possible to drive LED dot matrix.
