Expansion Connectors (J3 & J6)
The PandaBoard provides locations for two 28-pin, 0.1” through-hole expansion connectors, J3 and J6, to
support platform expansion (these connectors are not mounted on the current PandaBoard). The
placement of these connectors on the Panda PCB is shown below. On both connectors, the top left pin is
pin 1 and odd numbered pins are on the top row of the connector, and even numbered pins are on the
bottom row. See Figure 17 for the placement and orientation of these two connectors on the PandaBoard.
The distance between pin 1 of the two connectors is 300 mils or 7.62mm. Note that since these are
through-hole connectors, boards can be designed to plug into the PandaBoard from either top or bottom,
depending on user preference.
See Table 10 for the pinout of expansion connector “A” and Table 11 for the pinout of expansion
connector “B”. These tables show the primary function that is available on the connector pin, along with
the alternate function that can be selected by changing the OMAP4430 pin multiplexing. Some of the
OMAP I/Os have more than two possible functions, see Table 21 on page 58 for a complete list of the
functions available.
