OVERVIEW
Standalone Board Mode
A 24 key matrix panel is integrated into the E6248 together with LED key indicators. A 14-pin
header allows connection to an external matrix panel if required. To operate the board, plug it into a
live USB socket.
Main User Interface
This kit is designed for evaluation and development of QT60248 and QT60168-based behind-the-
panel touch matrix circuits. It includes all circuitry and materials required to make a fully-functioning,
24-key matrix touch control. This board has a virtual RS232 serial interface via the USB port that
allows connection to a PC for function setup and data viewing. The E6248 makes use of QmBtn™
software, which is included.
Chip/ Subsidiary Interface
The QT chip on this board uses SPI for communications. This is directly available on connector J4.
