Serial Interconnection between PSoC 5LP and CYW4343W
The PSoC 5LP device also has a secondary UART that is connected to the BT_UART of
CYW4343W (Murata Type 1DX).
Note:
BT_UART is also connected to PSoC 64 MCU on the carrier module and this is the
communication interface between the PSoC 64 MCU and the Bluetooth section of the CYW4343W.

Power Supply System
The power supply system on this board is versatile, allowing the input supply to come from the
following sources:
■
5 V from the onboard USB Micro-B connectors (
J6
and
J7
)
■
7 V–12 V from external power supply at VIN through barrel jack (
J5
) or from Arduino header pin
