R75 is mounted on the kit, which connects the hatch to the shield pin. This is required for liquid toler-
ance.
For details on using CapSense, design guidelines, and capacitive sensing, refer to
AN85951 - PSoC
4 and PSoC Analog Coprocessor CapSense Design Guide

A.2.10.1
CapSense Trackpad
The Flex PCB has a 14-element capacitive trackpad, which is connected to the PSoC 4100S pins.
This trackpad controls the LED color in
CE214025 Trackpad With Color Gamut
code example.
A.2.10.2
CapSense Proximity Sensor
The Flex PCB has one proximity sensor loop, which is connected to pin P1[6]. The proximity senor
loop in the PSoC 4100S Pioneer Kit can also be used as a guard sensor to make the sensors toler-
ant to streams of liquids.
This proximity sensor controls the LED brightness in
CE214023 Proximity Sensing
code example.
A.2.10.3
CapSense Buttons
The Flex PCB has two buttons, the left button (BTN1) is connected to pin P0[1] and the right button
(BTN2) is connected to pin P0[2]. These buttons control the LED brightness in
CE214025 Trackpad
With Color Gamut
code example.
A.2.11
LEDs
The PSoC 4100S Pioneer Kit has five LEDs. Three status LEDs (red, amber, and green) indicate the
status of the KitProg2. An amber LED indicates the status of power supplied to the kit. The kit also
has a general-purpose RGB LED connected to PSoC 4100S for user applications.
A.2.12
Push Buttons
The PSoC 4100S Pioneer Kit has a reset button (SW1) and two user buttons. The reset button is
connected to the XRES pin of the PSoC 4100S and EZ-BLE PRoC Module, and is used to reset both
the devices. One user button (SW2) is connected to P0 [7] of the PSoC 4100S device. The other
user push button (SW3) is connected to P1 [2] of the PSoC 5LP. All the buttons connect to ground on
activation (active low).
A.2.13
Cypress Ferroelectric RAM (F-RAM)
The PSoC 4100S Pioneer Kit contains an F-RAM device (
FM24V10-G
) that can be accessed
through I2C lines P3 [0] and P3 [1] of the PSoC 4100S. The F-RAM has a capacity of 1-Mbit (128
KB) with an I2C speed up to 3.4 MHz. The I2C slave address of the F-RAM device is 7 bits wide, and
the two least significant bits are configurable through physical pins. These pins are hard-wired to 00
on the board. By default, the address of the F-RAM device used on the kit is 0x50. This address can
be modified by changing the R68/R71 (A1) and R67/R70 (A2) resistor pairs. The operating voltage
range of the F-RAM is between 2 V and 3.6 V. To prevent the F-RAM from operating at voltages
greater than 3.6 V, the power supply to the F-RAM is derived from the output of the 3.3-V regulator.
The I2C lines are connected to the 3.3 V side of the onboard level translator to allow the F-RAM to
communicate with the PSoC 4100S operating at 5 V. For more information on using the F-RAM,
refer to
Using the FM24V10 F-RAM on page 44

A.2.14
EZ-BLE PRoC Module
The PSoC 4100S Pioneer Kit includes an
EZ-BLE PRoC Module
. The EZ-BLE PRoC Module is a
fully integrated, 10×10×1.8 mm, fully certified, programmable module designed for ease-of-use and
