The choice for 2.0 is based off my intents for this item to be used. The majority of keyboards, macro pads, mice, and other related peripherals do not have any use for 3.0. Additionally, 3.0 would limit what I'm wanting to do with this design:
- 3.0 controllers are on average larger than 2.0 ones, especially ones with more than 2 ports, and require more components and routing on the PCB, making the entire design even larger and costing more to produce
- 3.0 controllers are, on average, more expensive to buy, with the 2.0 ic I'm using being $.96 for a single one and the cheapest 4port 3.0 ic I've found being $10.20 for one and needing more components, which would impact the relatively low price point I'm looking to hit with these
- 3.0 requires different wire with 11 conductors that is not only more expensive, but larger, meaning that normal paracord would not work with it, so this would impact the pricing as well as the customization that I'm looking for
If I went with 3.0 and couldn't make my design small and clean, relatively cheap, and customizable, then why would anyone buy it over a $10 3.0 hub off Amazon?
