Connectors

4.1
This chapter describes the implementation of the relevant connectors and headers on AFE Control Board-SAM4C
and their connection to the ATSAM4C.
4.1.1

I/O Extension Headers

The AFE Control Board-SAM4C has a dual row, 20 pin, 100mil extension male header (J8). J8 offers access to
the I/O of the microcontroller in order to expand the board, e.g. by connecting extensions to the board. Table 4-1
shows the pin assignment of J8. User can also expand the function by customized development.

Communication Connector

The AFE Control Board-SAM4C has a dual row, 20 pin, 100mil communication male connector (J7). When
connecting to the daughter board, the AFE Control Board-SAM4C can communicate with it through J7. Table 4-2
shows the definition of J7.
