In addition to a beautiful full-colour TFT screen, seamless incorporation of a touch panel provides sleek
user input while a small piezo speaker and vibratory motor can offer audio and tactile feedback for a
completely interactive experience. Storage of fonts and bitmaps within the swappable onboard SD
memory card allows for a co-ordinated appearance in any design.
The elegant simplicity of the familiar Matrix Orbital command structure now provides updates to the
user and optional flow control for full two-way communication. Also new are animations, full-colour
graphs, automated display initialization, and field upgradeability.

Available flow controlled RS232 and TTL interfaces, as well as an I 2 C protocol provide versatile
communication schemes, while USB and RS422 versions ensure that any controller can have a beautiful
user interface. Scorching fast communication speeds, up to 256kbps in serial modes and 400kHz in I2C,
ensure important information is relayed on time.
