 A touch sensor system is built on a substrate which carries electrodes and relevant connections under a protective flat surface. When a user touches the surface, the capacitance variation is used to evaluate if the touch was valid.
 
-.. only:: SOC_TOUCH_VERSION_1

-    Touch sensor on {IDF_TARGET_NAME} can support up to 10 capacitive touch pads / GPIOs.

-.. only:: SOC_TOUCH_VERSION_2
-
-    Touch sensor on {IDF_TARGET_NAME} can support up to 14 capacitive touch pads / GPIOs.
-
 The sensing pads can be arranged in different combinations (e.g., matrix, slider), so that a larger area or more points can be detected. The touch pad sensing process is under the control of a hardware-implemented finite-state machine (FSM) which is initiated by software or a dedicated hardware timer.
 
 For design, operation, and control registers of a touch sensor, see *{IDF_TARGET_NAME} Technical Reference Manual* > *On-Chip Sensors and Analog Signal Processing* [`PDF <{IDF_TARGET_TRM_EN_URL}#sensor>`__].
