E6486

E6486 kit is designed for evaluation and development of QT60486 based glass touch matrix circuits. It includes all circuitry and materials required to make a fully functioning, 48 key matrix touch control. This board has an RS232 serial interface that allows connection to a PC for function setup and data viewing. This digital charge transfer IC are designed to detect human touch on up to 48 keys when used with a scanned, passive X-Y matrix. They will project touch keys to 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 16 pin header connector on the end of the board allows connection to a matrix panel. An LED status indicator shows detection and error states. The E6486 makes use of QmBtn software.

• QT matrix sensing through material of choice
• Wide variety of panel sizes and shapes
• Keys individually adjustable for sensitivity, response time and many other critical parameters
• UART interface
• Adjacent key suppression feature
• Synchronous noise suppression pin
• Spread spectrum modulation: high noise immunity
• Low cost per key
