MAX7219 dot matrix module ( Single )
MAX7219 dot matrix module ( Single )
100% Brand New & High Quality
Need only three IO port to drive a dot! No flicker when the dot matrix display! Support cascade!
Description:
1. Single module can drive an 8 * 8 dot matrix common cathode
2. Module Operating voltage: 5V
3. Module dimensions: length 3.2 cm X 3.2 cm wide X 1.3 cm high
4. Holes with four screws, diameter 3mm
5. Modules with input and output interfaces, support for cascading multiple modules
Wiring instructions:
1. On the left block to an input port, an output port on the right
2. When the control of a single module, simply enter the port received a CPU
3. When more than 3 modules cascaded output input termination CPU, the input output termination module of the first two modules of the first one,
the first two modules of the termination input terminal of the three modules, and so on
To 51 single example:
VCC → 5V
GND → GND
DIN → P2.2
CS → P2.1
CLK → P2.0
