System Design

System Block Diagram

Hardware Design

Overview

At a high level hardware integration requirements fell into two categories:

1. Reduce risk of unreliable cable connections and eliminate possibility of damage to components through unexpected disconnections, power surges, etc.
2. Provide a more fluid physical interface for the user to interact with the game via hardware


To accomplish these goals, two boards were designed: a breakout board and a gamepad controller. The breakout board serves as a connection hub between all system hardware components; power, the RGB matrix, the SJTWO board, etc. while the joystick provides a cleaner package to present the user with the games inputs. The diagram below shows the relationship between the main subsystems:

All board designs were done using EAGLE and manufactured by JLCPCB. Both boards were only two layers and used passive components for the most part.


Breakout Board Design

The breakout board design requirement was to interface all external hardware components with the embedded system (SJTWO). The hardware connections are:

1. The 64x64 RGB Matrix
2. Output power to the RGB Matrix
3. User game controller (see next section)
4. Input power supply (5V)
5. The SJTWO embedded system
