Comprising a built-in micro speak, audio amplifier, 3-stage audio filter and an LCD backlight control the credit-card sized board uses a SPI slave interface to communicate to the host microcontroller.
The second module in the series, the VM810C50A-N, excludes a display allowing engineers to select the size of screen to suit their application. Connected via the 40-pin FFC interface LCD screen sizes of 4.3 or 5 inch can be accommodated with SVGA, WVGA, WQVGA, or QVGA resolutions, along with a 4-wire resistive touch screen interface.
Both modules can be powered from a 5 VDC supply via the USB Micro-B port, SPI host connector or a 2 mm JST plug.
The FTDI FT81x EVE series of devices combine touch, display and audio capability on a single chip. Using an object-oriented to rendering graphics they can be displayed line-by-line at 1/16th pixel resolution and accommodate display resolutions of up to 800 x 600 pixels.
