CY8CKIT-041S-MAX PSoC™ 4100S Max pioneer kit guide
Kit operation
The PSoC™4100S Max pioneer board has the following peripherals:
1. Power LED (D2): This Yellow LED indicates the status of power supplied to board.
2. KitProg3 USB connector (J8): The USB cable provided along with the pioneer board connects between this
USB connector and the PC to use the KitProg3 onboard programmer and debugger and to provide power to
the board.
3. KitProg3 status LED (D3): This yellow LED indicates the status of KitProg3. For details on the KitProg3
status, see the KitProg3 User Guide.
4. KitProg3 (PSoC™5LP) programmer and debugger (CY8C5868LTI-LP039, U2): The PSoC™5LP device
(CY8C5868LTI-LP039) serving as KitProg3, is a multi-functional system, which includes a SWD programmer,
debugger, USB-I2C bridge and USB-UART bridge. For more details, see the KitProg3 User Guide.
5. KitProg3 programming mode selection button (SW3): This button function is reserved for future use.
Note that the button connects the PSoC™5LP pin to ground when pressed. For more details, see the
KitProg3 User Guide.
6. Voltage regulator (U3): The kit has an onboard regulator IFX1963 that is configured to generate 3.3 V, this
voltage is derived from the USB connector or from the external power supply connector.
7. PSoC™4100S Max MCU VDD power selection jumper (J10): This jumper is used to select the PSoC™4100S
Max MCU VDD supply voltage between 5.0 V and 3.3 V.
8. PSoC™4100S Max MCU VDD current measurement header (J11): An ammeter can be connected to this
header to measure the current consumed by the PSoC™4100S Max MCU.
9. PSoC™4100S Max MCU reset button (SW1): This button is used to reset the PSoC™4100S Max MCU. It
connects PSoC™4100S Max MCU reset (XRES) pin to ground when pressed.
10.Arduino-compatible power header (J1): This header powers Arduino shields. It also has a provision to
power the kit though the VIN input.
11.PSoC™4100S Max MCU program and debug header (J12): This 10-pin header allows you to program and
debug the PSoC™4100S Max MCU using an external programmer such as MiniProg4. It is not typically used
since the kit has an onboard programmer/debugger.
12.Arduino Uno R3-compatible I/O headers (J2, J3, and J4): These I/O headers bring out pins from the
PSoC™4100S Max MCU to interface with Arduino shields. Some of these pins are multiplexed with onboard
peripherals and are not connected to PSoC™4100S Max MCU by default. For detailed information on how to
rework the kit to access these pins, see 3.3 CY8CKIT-041S-MAX Kit rework.
13.PSoC™4100S Max MCU user button (SW2): This button can be used to provide an input to P11[5] pin of
PSoC™4100S Max MCU. Note that this button connects the PSoC™4100S Max MCU pin to ground when
pressed, so you need to configure the PSoC™4100S Max MCU pin as a digital input with resistive pull-up for
detecting the button press. This button also provides a wake-up source from low-power modes of the
device.
14.CAPSENSE™buttons (CSB1 and CSB2): Two CAPSENSE™buttons which can be configured as self-
capacitance (CSD) or mutual-capacitance (CSX) buttons, allow you to evaluate Infineon’ fifth-generation
CAPSENSE™technology. These buttons have a 3-mm acrylic overlay for smooth touch sensing.
15.User LEDs (D1, D4 and D5): These three user LEDs can operate at the entire operating voltage range of the
PSoC™4100S Max MCU. The LEDs are active LOW, so the pins must be driven to ground to turn ON the LEDs.
D4 and D5 LEDs are placed above CAPSENSE™buttons and can be used to show the CAPSENSE™button
status.
16.Flat Flex Cable (FFC) connector (J9): 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. The cable should be oriented so that the
metal contacts are down (i.e. against the top of the PCBs).
17.Thermistor (TH1): The sensor allows you to evaluate low-power analog blocks of the PSoC™4100S Max
MCU.
