# PmodTM Compatible mikroShield
# Overview
The PmodTM Compatible mikroShield is a simple mikroBUSTM add-on board that links the Digilent PmodTM Interface Specification to the mikroBUSTM standard.
The PmodTM Compatible mikroShield is fully passive and allows for connecting 6-pins and 12-pins PmodTM Compatible modules, as well as various wired sensors and breakout boards.
The Digilent PmodTM Compatible connector's supply voltage can be switched between 3.3 V and 5 V using the header, and the I2C pull-up resistors can be disconnected as necessary.
# Dimensions and Top & Bottom Views
