6.2 Expansion headers
The EVB provides a set of expansion headers to access the module IO pins. The assignments for
these headers are shown below.
• Signal with (DNS) is not connected by default, but can be connected with a 0Ω resister
• Signal with (0Ω) is connected by default, but can be disconnected by removing the 0Ω resister
