Kit Operation
2.2.2 USB-UART Bridge
The KitProg3 on the PSoC 62S1 Wi-Fi BT Pioneer Board can act as a USB-UART bridge.
The KitProg3 has two USB-UART bridges. The primary UART is connected to the PSoC 6 MCU and
the secondary UART is connected to the CYW43438. The primary UART can always be accessed
through USB, while the secondary UART can be accessed by changing the mode of the KitProg3 to
BULK with two UARTs Mode. For more details on the KitProg3 USB-UART functionality, see the
KitProg3 User Guide .
The primary UART and flow-control lines between the PSoC 6 MCU and the KitProg3 are hard-wired
on the board, as
Figure 2-15 shows.

The secondary UART and flow-control lines between the CYW43438 and the KitProg3 are hard-
wired on the board, as
Figure 2-16 shows.
