Piggyback Adaptor Boards

Piggyback adaptor boards were developed to accommodate variations in pin configurations on modules that were otherwise intended to use the same parent PCB header. These have been used most often on modules employing an I²C interface, as described in the I²C pages elsewhere on this website.

The other situation in which a piggyback adaptor has been useful is in using one of the 'standard' headers on a prototyping board for a purpose other than that for which it was originally intended. In this situation, the piggyback board is simply patching the pins of the relevant module into the appropriate prototyping board connections, as is the case when configuring the MPS20N0040D air pressure sensor module described on the relevant sensor page elsewhere on this website.
