1.3 ModusToolbox™
ModusToolbox™is a free software development ecosystem that includes the Eclipse IDE for ModusToolbox™,
AIROC™BTSTACK, Bluetooth® SDK, and the PSoC™ 6 SDK to develop applications for Infineon IoT products.
Eclipse IDE for ModusToolbox™is a multi-platform, integrated development environment (IDE) used to create
new applications, update application code, change middleware settings, and program or debug applications.
Using ModusToolbox™, you can enable and configure device resources and middleware libraries, write C source
code, and program and debug the device. The build system infrastructure includes the new project creation
wizard that can run independently of the Eclipse IDE, the make infrastructure, and other tools. This means you
can choose your compiler, RTOS, and ecosystem without compromising usability or access to our industry-
leading CAPSENSE™ (Human-Machine Interface), AIROC™ Wi-Fi and Bluetooth®, security, and various other
features.
The Infineon’s AIROC™ BTSTACK is a software implementation of the Bluetooth® core 5.4 host protocol stack.
The stack is hosted as a library on Infineon’s GitHub. The stack library includes both Bluetooth® BR/EDR and
Bluetooth® Low Energy hosts and provides APIs for them. The application can choose to use Bluetooth® Low
Energy or both BR/EDR + LE. The stack is available for different Arm® cores, such as CM4 and CM33, and can be
used with three toolchains Arm®, GCC, and IAR.
For more details on ModusToolbox™installation and usage, see the ModusToolbox™ user guide.

Kit operation
1. Power indicator LED (LED1): This LED is used to indicate the status of power supplied to the board.
2. USB connector (J5):J5 is a Micro-B USB female connector for connecting the kit to the PC using the
provided USB cable. It is used for programming and USB-UART communication.
3. KitProg3 Programming mode selection button (SW3): In this kit by default, it supports CMSIS-DAP BULK
mode. The button connects the PSoC™ 5LP pin to the ground when pressed. For more details, see the
KitProg3 user guide.
Note: Dual UART mode is not supported because there is no hardware connection between KitProg3 and
M.2 interface.
4. KitProg3 (PSoC™ 5LP) programmer and debugger (CY8C5868LTI-LP039, U5):The PSoC™ 5LP
(CY8C5868LTI-LP039) serving as KitProg3, is a multi-functional system, that includes a Serial Wire Debug
(SWD) programmer, debugger, USB-I2C bridge, and USB-to-UART bridge. For more details, see the KitProg3
user guide.
5. VDDPA select jumper (J12): This jumper is used to select the VDDPA (power amplifier supply) power
source. The possible selections are 3.3 V or VCOIN (3 V) which is the coin-cell power supply on the bottom
side of the board.
6. VIO_BASE select jumper (J10):This jumper is used to select the VIO_BASE power source. Possible
selections are 3.3 V, 1.8 V, or VCOIN (3 V), which is the coin-cell power supply on the bottom-side of the
board.
7. VBAT select jumper (J9): This jumper is used to select the VPA_BT (core power supply) power source. The
possible selections are 3.3 V, 1.8 V, or VCOIN (3 V) which is the coin-cell power supply on the bottom-side of
the board.
8. Analog mic (U13):It can be used to configure the kit as a voice remote.
9. Arduino-compatible header (J1): The Arduino-compatible I/O header brings out power and reference
voltage pins from the base board to interface with Arduino shields.
10. Reset button (SW1, XRES): This button can be used to reset the device.
11. Debug header (J13): J13 is a 10-pin interface header that can be used to connect an external
programmer/debugger via SWD.
Note: Use J13 only to connect a programmer/debugger. A voltage mismatch occurs if something else is
connected to J13 to communicate with KitProg3.
12. Arduino-compatible header (J2): The Arduino-compatible I/O header brings out pins from CYW20829 to
interface with Arduino shields.
13. User button1 (SW2): This button can be used to provide input to the CYW20829 device. Note that the
button connects the CYW20829 pin to the ground when pressed; therefore, the CYW20829 pin must be
configured as a digital input with a resistive pull-up for detecting the button press.
14. Digital mic (U11):The digital microphone ASIC contains an extremely low-noise preamplifier and a high-
performance sigma-delta ADC. It can be used to configure the kit as a voice remote.
15. User button2 (SW4): This button can be used to provide input to the CYW20829 device. Note that the
button connects the CYW20829 pin to the ground when pressed; therefore, the CYW20829 pin must be
configured as a digital input with a resistive pull-up for detecting the button press.
16. User LED2 (LED4): These onboard LEDs can be controlled by the CYW20829 device. The LEDs are ACTIVE
LOW; therefore, these pins must be driven low to turn ON the LEDs.
17. User LED1 (LED3): These onboard LEDs can be controlled by the CYW20829 device. The LEDs are ACTIVE
LOW; therefore, these pins must be driven low to turn ON the LEDs.
18. M.2 Stand Off (MT1):Stand to connect M.2 card

19. CYW20829 (U1): The Bluetooth® Low Energy 5.4 qualified system-on-chip from the Infineon is the heart of
this evaluation kit.
20. M.2 E key connector (J16): This is used to interface Infineon custom Bluetooth® Low Energy M.2 boards to
this kit.
21. RGB LED (LED5):These onboard LEDs can be controlled by the CYW20829 device. The LEDs are ACTIVE LOW;
therefore, these pins must be driven to the ground to turn ON the LEDs.
22. Thermistor (TH1): The onboard thermistor is an NTC analog thermistor that can be used to measure
temperature.
23. Thermistor enable jumper (J14): This jumper can be used to connect or disconnect the onboard
thermistor from the CYW20829 device.
24. Peripheral enable (J13): The jumper allows the user to connect and disconnect the VDDIO supply to
onboard peripheral devices such as the IMU, thermistor, analog mic, and real-time clock by disabling VDDP.
25. VDDIO current measurement jumper (J17): This jumper is used to power the carrier module. Remove this
jumper and connect an ammeter to the two pins to measure the current the carrier module uses.
26. 6-axis IMU(U12):This is an I2C-based 6-axis IMU sensor.
27. 1-MB serial flash (U14): This is the 1-MB QSPI flash used for application purposes (no load by default).
28. Arduino-compatible header (J4 and J3):The Arduino-compatible I/O header brings out pins from
CYW20829 to interface with Arduino shields.
29. Digital I/O headers (J18):Extended GPIO headers for extending the additional GPIOs from the CYW20829
device.
