“The project is a sample project about how matrix monitors works. The scroll speed can be set by a potentiometer. A Bluetooth module added to the project. So, you can send texts to your board with a smart phone. A 3dprinted stand designed for the PCB. So you can place your board on a table and enjoy!
Two PCBs Designed in Altium Designer for two level board. First level, is the controller level. The microcontroller is placed in this level.
Second level, is the matrix level. 128 LEDs placed in this level in 8 rows and 16 columns. The second level is connected to the first level with 24pins pin-header.”
