Good afternoon everyone. I hope everyone are fine and doing well.
I am Bharath S. I am studying electronics engineering.
I am currently working in scoreboard project for my ground. I want to make bigger scoreboard. Approximately 100cm width and 50 cm height. I saw many tutorials in adafruit but every tutorial is only for smaller matrices.
In order to make large display board( 100cm width X 50cm height), what type of microcontroller we need to use? Is Adafruit Matrix portal enough to build this much larger board?
The size of the dashboard is not so important. It is more important what LEDs (smart or ordinary) you use and how many. Depends on whether any animations and / or effects will be used. If you are going to use regular LEDs and only show large 7 segment numbers, an Arduino Nano may be enough. However, you will also need a suitable power supply because many LEDs need a lot of power. You have not specified what exactly you will do and I'm just guessing.
Here I am using 32x32 RGB matrix matrix from Adafruit. I am going to construct large matrix by cascading 8 32x32 RGB matrix in horizontal and 4 32x32 RGB matrix in vertical. So total of 32 matrices. And also I am going to display text with scrolling effect, displaying images and gifs as well.
So I am really confused to choose microcontroller to use. Please help me out with this.
32 * 32 * 32 * 3 / 1024 = 96K of RAM just for the single frame buffer, so you should have a good bit more.
32 * 4A = 128A @ 5V
You can use those requirements to search for uController power supply cantidates. Fortunately you can use multiple power supplies but I would recommend a single uController with enough ram to handle the job.
