FFC connector for expansion board
A 40-pin bottom-contact
flat flex cable (FFC) connector is provided, on the
pioneer board, to bring out the
CAPSENSE
™ pins of
PSoC
™
4100S Max MCU. This connector is used to connect the expansion board to the
pioneer board. This connector brings out 29 I/Os of PSoC
™
4100S Max MCU. Refer
section for information on precautions that needs to be taken while connecting and disconnecting
the flex cable.

CY8CKIT-041S-MAX capacitive sensing expansion board
The expansion board connects to the pioneer board using the 40-pin FFC connector. The expansion board has
two FFC connectors that connect the I/Os of PSoC
™
4100S Max MCU to either the Touchpad and proximity
section or to the Slider section.
3.2.11.1
Touchpad and proximity interface
The Expansion board consists of a 160-segment Touchpad that has 10 rows and 16 columns. The board also has
a proximity loop with ~11 cm diagonal length that can demonstrate a proximity range of about 18 cm distance.
