MAX7219 8X8 Dot LED Matrix Display Module
The MAX7219 is compact, serial input/output common-cathode display drivers that interface microprocessors to 7-segment numeric LED displays of up to 8 digits or 64 individual LEDs. It includes an on-chip BCD code-B decoder, multiplex scan circuitry, segment and digits drivers, and an 8×8 static RAM that stores each digit.
Features:
- A single module can drive an 8*8 common cathode matrix
- 4 fixing screw holes, 3mm aperture , can be fixed with M3 copper column
Specification:
| Specification | Value |
|---|---|
| Supply voltage | 5 V |
| LED matrix | 8 x 8 |
| Communication interface | SPI |
| LED color | Red |
| Module dimensions | 50 x 32 mm |
| Matrix dimensions | 32 x 32 mm |
The set includes a display matrix of LEDs 8 x 8 complete with a controller and all necessary passive elements. The MAX7219 control system communicates via the SPI bus, which means it can be easily controlled using microcontrollers, including AVR and Arduino modules. The description, together with a library and a sample program for users of Arduino can be found here.
To start the module with Arduino using the library, you must connect: DIN – PIN 12, CLK – PIN 11 CS – PIN 10.
Outputs are in a form of popular goldpin connectors (2.54 mm raster) for connecting the sensor via wires or directly to the breadboard.
For manual assembly you can check this product or this one.
Package Includes:
- Printed circuit coard with MAX7219 driver and 8×8 matrix
- 5x cable female-female – 20 cm
