Firmware Pinout
The interface between the Infineon PSoC microcontroller mounted on the CY8CKIT-059 Prototyping Kit (RKX-A3-EVK-001 headers J14, J15)
and the sensors mounted on the evaluation board, and either plugged directly to J6 (18-pin receptacle header) or via ribbon cable plugged into J5
(14-pin male header) on the RKX-A3-EVK-001 is shown in Table 5.
