EVBCRTOUCH

EVAL BOARD, TOUCHSCREEN SENSE, USB

The is a Xtrinsic CRTouch capacitive and resistive touch sensing platform evaluation board. It enables resistive touch screens to handle two touch gesture recognition and allows the addition of up to four capacitive electrodes to system, all packaged on a 5mm x 5mm 32 pin QFN. It supports four and five wire touch screens and communicates over UART and I2C communication protocols. The implementation of these technologies enables the CRTouch to help reduce space, cut software development costs and speed time to market.
