it’s a good idea to write what each maker would appreciate in his ideal board,
i’d like khadas to adress multimedia player usage, but also server usage,
for which the board shall cost less than 70USD,
have onboard emmc (16G+),
I agree with the un necessity of 2x20 pins to look like the rpis
separate power socket is a must, but a small factor one, like what we have on modern laptops;
no need of tiny JST, no mipi, no csi socket, more than 2 usb sockets : at least one usb-A and two usb-c, no huge hdmi port, just a mini one,
the idea behing rpi compute module is good, consider to be compatible with their pinouts to benefit from existing “motherboards/carrier boards” and focus only on CPU boards that can evolve often,
propose a least one risc-V based SOC;
consider replacing the wifi-BT module w/ an ESP32 as a coprocessor and expose its GPIOs;
the embedded 8bit mcu is not so useful for us, remove it.
