The host board will typically have a 12-pin right angle female connector at the board edge for direct connection of
peripheral module boards, however a straight female connector inboard from the board edge is also allowed.
When multiple Pmod host ports are placed side-by-side along a host board edge, they are spaced 0.9” center-to-
center. This allows for 0.8” wide modules to be plugged side-by-side into a host without mechanical interference.
Peripheral modules with multiple male connectors must also have them spaced on 0.9” centers for direct
connection to a host.
Peripheral modules with a single connector that are intended for direct connection to a host, or that are intended
to fit into the Pmod mounting clip, should be 0.8” wide. There should also be >25 mil of clearance from the board
edge to any components to allow clearance for the Pmod clip to latch the board edge. The connector should be
centered along the 0.8” side of the module.
Peripheral modules that are more than 0.8” wide can be directly connected to a host in most cases but may
interfere with adjacent host ports.
The following diagrams show physical connector placement and pin numbering conventions for the host (system
board) and peripheral module sides of the connection. Note that the pin numbering conventions for the 2x6
connectors are non-standard and are mirrored between the host connector and the peripheral board connector.
