The Pandaboard ES 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 ES). 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 16 for the placement and orientation of these two connectors on the Pandaboard
ES. 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 ES from either top or
bottom, depending on user preference.
See Table 11 for the pinout of expansion connector “A” and Table 12 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 OMAP4460 pin multiplexing. Some of the
OMAP I/Os have more than two possible functions, see Table 22 on page 55 for a complete list of the
functions available.
