The pins in the front expansion area of the Zumo Shield are shown in the following diagram:
{{POLImage|Pololu-Zumo-Shield-Arduino-extension-avant-00.png|599px|Brochage de l'extension avant}}
This diagram is also available as a downloadable PDF: [https://www.pololu.com/file/download/zumo_shield_front_expansion_pinout.pdf?file_id=0J592 Zumo Shield front expansion pinout] (''552k, pdf, pololu.com'').
The front expansion makes available digital pins 2, 4, 5, and 11 and analog pins A0 through A5. It also provides access to the two I²C pins (SDA and SCL). However, please note that the I²C pins are not independent pins; they are respectively duplicates of analog pins A4 and A5 on the Uno R3 and digital pins 2 and 3 on the Leonardo and A-Star 32U4 Prime. Typically, you will only be able to use these pins for either I²C communication or general I/O, not both. Additionally, pin A1 is used to monitor the battery voltage if you install the battery monitor jumper.
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.
