Hobbyists and makers now have more flexibility and options when developing LED signs, using the MAXREFDE99# 16x16 display reference design from Maxim.
LEDs continue to dramatically transform signage and lighting. However, often LED displays today are 8x8 and cannot communicate many international alpha-numeric characters. MAXREFDES99# integrates four MAX7219 LED drivers to provide designers a 16x16 display with 256 LEDs, allowing them to create signs in multiple languages. The MAX7219 driver simplifies the process of controlling multiple LEDs in matrix or numeric display form. For fast prototyping, software code developed for the MAXREFDES99# reference design works with both ARM mbed and Arduino platforms. Developers are encouraged to build upon and enhance the code base for more signage possibilities.
