Expansion headers
The Rapid IoT connect developer kit contains two single inline headers (J1 and J5). All pins of the PSoC™ 6 MCU
device that are not dedicated to a function are connected to the stackable expansion headers. The I/O header
signals include signals from PSoC™ 6 MCU and system power signals.

QSPI
This board has a 24-BGA 512 Mbit QSPI NOR flash. This device uses a Serial Peripheral Interface (SPI) to
communicate with the PSoC™ 6 MCU device. The device supports four-bit (Quad I/O) serial commands. The
PSoC™ 6 MCU device supports up to 70MHz clock on the QSPI interface. 33Ω series termination resistors are
provided as close as possible to the module footprint on the clock and all I/O lines.
