E6248

E6248 kit is designed for evaluation and development of QT60248 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. QProx QMatrix ICs detect human touch on up to 24 keys when used with scanned, passive X-Y matrices. They project touch keys through almost any dielectric like glass, plastic, stone, ceramic, and even wood up to thicknesses of over 5cm. Touch areas are defined as simple two part interdigitated electrodes of conductive material deposited on the rear of a control panel. 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. The E6248 makes use of QmBtn software.

• QT chip on this board uses SPI for communications
• Button touch sensor type
• 24 touch channels
• Sensitivity of each key can be set individually
• Key setups are stored in an onboard EEPROM and do not need to be reloaded with each powerup
