How is the Milk-V Duo S able to hit these extremely low price points? Are they selling at a loss or making some sort of market play? I've looked into integrating PoE modules into an ESP32-C3, and the bill of materials adds up quickly. That's not to mention that this is a 3-core SoC with vastly higher clock speeds and available memory. I have some projects that would really benefit from these specs at this price point, but is there some sort of catch?
