Display

...

• Ideally want RGB support—want to have RGB rainbows etc
  • This only really works with an LED matrix though, an RGB rainbow on an LCD/OLED display is boring
• Should have sufficient resolution to display the logo
  • Minimum size of LEDs to effectively show pathfinding

I will need to consider, among other things:
1. Operating voltages;
2. Typical current draw;
3. Communication/driving protocol (data lines required, microcontroller peripherals needed); and
4. Cost.

First, I will begin by doing a Parts Selection by comparing different options, and selecting the device(s) that I think will be the most suitable.

Having evaluated the different options I can elect to go with, I have decided to proceed with a Discrete LED Matrix, and specifically the preferred devices identified in Discrete Non-Addressable RGB LEDs.

Having done my parts selection, I will move on to a Layout Design in Figma using my selected devices to design the matrix layout and topology itself.

After choosing my Shift Registers and LED Drivers to drive my matrix, I will work through determining the Design Parameters that I will need to know in order to use the selected LED driver.

I also needed to design a simple Current Amplifier stage for the common-anode input of each LED, as the shift register can only source per output.

Lastly, I needed to determine the necessary VLED Bypassing Capacitors to produce a 'well-regulated LED supply voltage ().
