Please note that only components and connectors in the {{underline|front three rows}} of pins can extend below the shield; the fourth row covers the chassis and is only suitable for components mounted above the shield.

If you use an Arduino Uno R2 or an older Arduino, which lack separate I²C pins, the SDA and SCL pins on the Zumo Shield will not be connected to anything. To use an I²C device on those pins, you can connect SDA to A4 and SCL to A5 yourself by bridging across those two sets of pins in the front expansion area. Section 3.c further explains the I²C lines and the jumpers connecting them to the on-board compass module.
