Header descriptions
The OSD3358-SM-RED board has 2 main expansion headers J5 and J6 that have the same
pinout as Bealgebone Black headers P8 and P9 if the jumper J11 is unpopulated. The pinout is
shown in the Figure 62. Detailed information regarding the pinout and multiplexing of each pin is
described in section ‘Connectors’ of the Bealglebone Black reference manual.
