The CP2501 Development Kit includes a motherboard that interfaces to a daughter board. The CP2501
Development Daughter Board contains a CP2501 device to be used for preliminary software development.
Numerous input/output (I/O) connections are provided on the motherboard to facilitate prototyping. Figure 3 shows
the CP250x Motherboard and indicates locations for various I/O connectors and shows the factory default shorting
block positions. Figure 4 shows the available CP250x daughter board.
