Shield Board
A.2.2.1
CapSense Circuit
CapSense Gesture Pad
The shield board includes a five-element CapSense Gesture Pad along with an eight-element radial
slider, which are connected to PSoC 4200L (marked 24 in
). All the pins on the
CapSense Gesture Pad are connected to the CSD0 block of PSoC 4200L. The Gesture Pad is used
to emulate mouse actions, joystick, LED color/intensity controls, and audio playback controls in the
code examples and can be used for general purposes. The CMOD and CTANK capacitors essential
for CapSense functionality are connected close to the PSoC 4200L device on the main board. See
for details on the CMOD and CTANK capacitors.
Proximity Headers
The shield board contains two headers (J21 and J22) for CapSense proximity wire connection
(marked 22 in
). If the proximity functionality is not being used, these pins can
be used as standard GPIO pins.
Note:
PSoC 4200L supports dual-channel capacitive sensing and the proximity pins are connected
to the second CapSense block (CSD1). As a result, when using the proximity sensors in your
design, CMOD1 will be required to implement the capacitive sensing. CMOD1 is populated on the
board by default; you need to select the appropriate CMOD pin (P5[0]) in the PSoC Creator to suc-
cessfully build and use the design.

Expansion Connectors
Arduino-compatible Headers (J17, J18, J19, J20, and J24)
The PSoC 4 L-Series Pioneer Kit has five additional Arduino-compatible headers on the shield
board–J17, J18, J19, J20, and J24. Header J17 is marked 18 and headers J18, J19, and J20 are
