2.2.2 Design Size

Another key consideration in this design was creating a small design size while having a good efficiency. Generally, more compact designs have less space for cooling, causing heat dissipation problems, leading to reduced performance abilities. Additionally, placing components closely together can cause signal interference and a need for higher routing accuracy. This design prioritized having a small and compact design size while maintaining a reasonable efficiency.
