The TOUCH DATA connector found on QT600 interface board is used for streaming touch data to the PC. It has three interfaces ‒ TWI, UART and SPI (UART is at the moment not supported in the software). The same connector is found on the Touch MCU boards. A 10-wire cable can be connected between these two connectors.
