Expansion Connector - Seco SBC-A62-J User Manual

3.3.15 Expansion connector

The SBC-A62-J board offers the possibility of accessing directly to some of the various features offered by i.MX6 processor through the pin multiplexing.
This means that onboard there is a dedicated 32-pin connector, J8, which is a standard dual-way male pin header, p=2mm, h=
4mm, type Townes P1022-2*16MGF or equivalent.
The pinout of this connector is shown in the following table. In there, near each pin name, it is also indicated the possible uses of those pins, according to the pin
multiplexing possibilities of i.MX6 processors. Port numbering is written only for easier identification, but each pin can be individually set, independently from the
use of the other pins of the same port.
Due to the various pin multiplexing possibilities offered by i.MX6 processor, in the following table are shown the features supported by SECO's BSP. It is also
shown the i.MX6 pad name connected to each pin of connector J8, for the users who want to explore different configurations not directly managed by the BSP
provided.
