10-pin SWD header

A 10-pin (50 mil pitch) SWD header is provided for the programming and debugging of the target CYW20829
device using an external programmer such as MiniProg4.
VDDIO (3V3/3V/1V8) will be supplied from the onboard LDO via reverse protection circuit to restrict Kit
operation by the programmer power.

Arduino-compatible and extended headers

The baseboard supports the generic Arduino-compatible Uno shields and selected Infineon custom defines
Arduino-compatible shields. All the CYW20829 GPIO pins are brought out to Arduino-compatible headers. Some
pins with fixed functions are also multiplexed through 0 Ω or jumper and connected to the headers.
The I/O headers J1-J4, whose position and pin map comply with the Arduino-compatible UNO R3 kit to support
Arduino-compatible shields. The system power signals are brought to the pins of J1.
The power supply pins for Arduino-compatible VCC_ARD_3V3 and VCC_ARD_5V0 connect to VCC_3V3 and
KP_VBUS through reverse voltage protection circuits.
All GPIOs of the CYW20829 device are at 3V3/3 V/1V8 level-based on the selected jumper position in VDDIO
power selection. To establish compatibility with the existing Arduino shields, all GPIOs are level mapped with
the same VDDIO in the baseboard.
