... 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 for function setup and data viewing. The E6486 makes use of QmBtn™ software, which is included. The QT chip in this board uses two interfaces: SPI for high-speed synchronous communications or RS232 for communications with a PC ...
