The Elite version is the cheap one without too much peripheral devices on it. Currently supported are serial console, wired networking(USB), USB OTG in peripheral mode, USB host, SD storage, GPIO buttons, PWM beeper, ADC and LEDs. The WM8960 analog audio codec is also enabled. The FIMC is not used for camera currently, I enabled it just for a colorspace convertor.
