Similarly to the Romi mounting holes used for the Arduino, the mounting holes used for the Raspberry Pi are also on surfaces of two different heights. As mentioned above, a few spacers <mall>([https://www.pololu.com/category/93/spacers lien pololu])</small>can be used to raise the board to an appropriate height. However, when using a Raspberry Pi, it can be beneficial to raise the board even more, enough to allow access to the HDMI port by simply removing a motor from a motor clip. To do this, the Raspberry Pi should be raised about 15 mm above the top of the battery box. This can be accomplished with two 25 mm spacers for the front mounting holes and two 15 mm spacers for the rear ones. Please note that using such long spacers will require some uncommonly long #2-56 or M2.5 screws.

An alternative solution is to use some of our {{pl|608|11 mm aluminum standoffs for the Raspberry Pi}} {{polpl|1952}}, which is especially helpful when using a Raspberry Pi HAT or expansion board since the same standoff can be used to mount that board to the Raspberry Pi. Stacking two of the 11 mm standoffs for the front mounting holes can help compensate for the longer distance; however, to reach the height previously mentioned to access the HMDI port through the motor clip, you will need to use some nuts or washers for the extra few millimeters as shown below:

If you are using a Raspberry Pi for controlling the Romi, you might consider our {{pl|503|DRV8835 Dual Motor Driver Kit for Raspberry Pi}} {{polpl|2753}}, the {{pl|704|A-Star 32U4 Robot Controller with Raspberry Pi Bridge}} {{polpl|3117}}, or one of our other Raspberry Pi Expansion Boards <small>([https://www.pololu.com/category/188/raspberry-pi-expansion-boards lien Pololu])</small>.
