5. Evaluation Board Overview
The CP2110 Evaluation Kit includes an evaluation board with a CP2110 device pre-installed for evaluation and
preliminary software development. Numerous input/output (I/O) connections are provided to facilitate prototyping
using the evaluation board. Refer to Figure 3 for the locations of the various I/O connectors.
5.1. LED Headers (J3, J4, J5, J6, J7)
Connectors J3, J4, J5, J6, and J7 are provided to allow access to the 10 GPIO pins on the CP2110. Place shorting
blocks on these headers to connect the GPIO pins to the 10 green LEDs D0 - D9. These LEDs can be used to
indicate active communications through the CP2110. Table 1 shows the LED corresponding to each header
position.
