Sooner or later, both Arduino enthusiasts and beginners will encounter the MAX7219 IC. And for good reason, it is a simple and somewhat inexpensive method of controlling 64 LEDs in the form of a numeric or matrix display. Plus, they can be daisy-chained to control two or more units for even more LEDs. All in all, they are a lot of fun and can also be quite useful.
Features:
- Size: 50mm x 32mm x 15mm
- Module operating voltage: 5V
- A single module can control an 8x8 common cathode grid
- With four screw holes, 3mm aperture
- Module with input and output interfaces, supports multiple cascading modules.
