PMOD connector spacing

[Solomon Kalbore]

Hello,

Please, I would like to know the exact spacing between two PMOD headers. (i.e. From the center of pin 1 of one header to the center of pin 1 of the next header.)

Thank you.

Hi @Solomon Kalbore,

I answered a similar question here. In short, the center-to-center distance between two PMOD headers is 0.9", so the center-to-center from pin1 on one header to the next should be the same as well. The comment includes a link to the PMOD standard, which has other bits of info should you need it.

Here is the relevant phrase from the PMOD Specification document:

"When multiple connectors are placed side-by-side along a board edge (either host or peripheral), the connectors are spaced 0.9”, center-to-center. This allows for 0.8” wide modules to be plugged side-by-side into a host without interference. Peripheral modules with multiple connectors must also have them spaced on 0.9” centers for direct connection to a host."

.9" is 22.86mm, so it looks like you have it correct.
