Introduction to ConnectEVE
The ConnectEVE board contains FT800Q
graphic controller and 4.3" TFT color display
AT043B35 with 480x272 pixel resolution,
which is driven by HX8257A display controller,
capable of showing advanced graphical
content. Each pixel can display 262K different
colors. TFT display is covered with a resistive
touch panel which can be used as input device.
The board is primarily designed to be used as
additional display on mikroElektronika Easy
development boards. For further connectivity
there are two headers (2X5 and 1X10). After
testing and building the final program, this
board can also be used in your final device. The
board also contains mounting holes for easier
integration into your designs.
