Hardware
3.2.1 Serial communication between CYW20829 and PSoC™ 5LP KitProg3
The onboard CY8C5868LTI-LP039 PSoC™ 5LP device is a true programmable embedded system-on-chip
responsible for two-channel USB-serial conversion on this baseboard. The USB-serial pins of the PSoC™ 5LP
device are hard-wired to the HCI UART pins of the CYW20829 device.
Use the mode switch SW3 to switch between various modes of operation of KitProg3. Note that this board
supports only CMSIS-DAP BULK mode. This button function is reserved for future use. The status LED (LED5)
indicates the current mode of KitProg3.

Power

The power supply system on this board is versatile, allowing the input supply to come from the following
sources:
5 V from KitProg3 Micro USB Type-B port
•
3 V from coin-cell
•
These input source sections can have transient voltage suppression (TVS-diode) to provide ESD protection for
the power source at the connector.
The Amber power LED is connected to the VCC_3V3 rail through a current limiting resistor to indicate the board
power is ON.
The PSoC™ 5LP (KitProg3) is powered from the KP_VBUS rail with a 0 Ω resistor/jumper in series so that
PSoC™ 5LP can be disconnected from the supply rail easily or can be used as a current measurement jumper.
On the other hand, KP_VBUS also goes to the Arduino Header (J1) as VCC_ARD_5V0 through a reverse voltage
protection circuit.
The kit can have a buck regulator that generates 3V3, 2V5, and 1V8 for VBAT/VDDIO/VDDPA and eFuse voltages
of the CYW20829 devices.
The regulated output VCC_1V8 from LDO will go to the peripherals: IMU, thermistor, DMIC, RGB LED, and AMIC
through jumper and Arduino-compatible header as VDDIO reference through reverse voltage protection.
