The most common problem with tvboxes is that most of their Wi-Fi and Bluetooth devices are not supported by Linux Kernel.
H616 is inferior compare to old H6, rk3318 is inferior compare to rk3328, S905x4 is closed for opensource community contrary to the old S905x3. The latest new models are almost always inferior to their predecessors or they are much pricier, so you'd better hurry up before the old models run out. The current supply crisis has unfortunately also affected the tvbox market. I only choose devices that support USB 3.0 as this is an important feature for most USB grabbers. For example, testing popular and cheap tv-boxes by trying to install Linux OS on them. Even the new Raspberry Pi Zero 2W that was recently tested is no longer available or costs over $ 30 in my country, so we have to look elsewhere.
The optimal solution like the Raspberry Pi 4 with USB3.0 is not available in the market or the price is about 4 times the initial price. With the latest review, I want to open a new chapter for new platforms that can be the hardware base for HyperHDR. With the help of my Github sponsors (thank you!) I have the opportunity to test different hardware such as grabbers and other IoT devices like ESP8266 / ESP32 to check HyperHDR compatibility or design new software for them like HyperSerialESP8266/HyperSerialEsp32/HyperSPI etc.
