Kit Hardware
2.4.7
UART Connection
A dedicated connection is provided to connect the PSoC 4 I/O pins on J4-1 and J4-2 to the KitProg
UART pins on J6-1 and J6-2. The J6 shield pins connect to the pioneer kit’s KitProg J8 header, pin
J8-9 (UART TX) and J8-10 (UART RX). The PSoC 4 device used on the CY8CKIT-040 kit does not
provide a UART peripheral; therefore, the UART connection is not used with this kit. All other
Pioneer kits provide an onboard UART connection; therefore, the J6 connection is not used with
these kits. The UART connection shown in
allows the liquid level sensing firmware to
implement a terminal interface for user interaction.

Liquid Container
The 32 oz Square PET plastic liquid container is provided for use with the flexible sensors. User
supplied container can be used in its place if it is compatible with the sensor dimensions. You can
also purchase the kit container (Item Number: 70348) from
Hot water above 170 °F/80 °C can cause PET plastic to deform. Extremely hot water should be
avoided as the liquid container provided in the CY8CKIT-022 kit is made of PET plastic.
