The HD223 and HD1023 are designed to be used between 0°C and 40°C, at 90% maximum relative humidity, non-condensing.
The power supply for the HD223 and HD1023 is 18W (12V@1.5A). The device will use less than 11W of power when playing a 1920x1080x60p H.265 (HEVC) source file.
An additional 6W of power is available for peripherals connected to the player. This is sufficient to provide up to 1A at 5V on the USB 2.0 port and up to 0.5A at 3.3V on the GPIO 3.3V pin.
