Products Description:

MAX7219 Dot Matrix Module 4 in 1

100% brand new and high quality
A convenient four-wire serial interface can be connected to all common microprocessors. Each data can be addressed at the time of updating without having to rewrite all the displays. The MAX7219 also allows the user to select or not code for each data.
The entire device contains a 150μA low power shutdown mode, analog and digital brightness control, a scan limit register allows the user to display 1-8 bits of data, and a test mode for all LEDs to emit light.
Only need 3 IO port can drive a dot matrix! Dot matrix display without flicker! Support cascade!

Module parameters:
1. A single module can drive an 8 * 8 coin lattice
2. Module operating voltage: 5V
3. Module size: Length 12.8 cm X Width 3.2 cm X Height 1.3 cm
4. With 64 fixed screw holes, aperture 3mm
5. Module with input and output interfaces, support multiple modules cascade.
6. Light Color: Blue/Green/Red
