The VM810C50A-D features a 5.0-inch TFT display with WVGA resolution and a resistive touchscreen. Conversely, for the VM810C50A-N, the display is not included. Instead, through use of its 40-pin FFC interface, a suitable 4.3/5.0-inch LCD (with SVGA, WVGA, VGA, WQVGA or QVGA resolutions and a 4-wire resistive touch screen interface) may be attached, meaning that the appropriate display can be connected.
Both of these units act as SPI slaves connecting to the specified system microcontroller through their single SPI interfaces. They each have a built-in micro speaker, audio power amplifier, 3-stage audio filter, audio line out option and LCD backlight control. Power can be drawn for these modules via either the 2mm power jack, the USB Micro-B port or SPI interface. The SPI interface supports 5V tolerant buffers when using a 5V SPI supply.
