The Romi chassis also has mounting holes intended for use with a Raspberry Pi. These holes support the form factor and mounting hole locations used on the Raspberry Pi A+, Raspberry Pi B+, Raspberry Pi 2 Model B, and [https://shop.mchobby.be/fr/30-raspberry-pi-3 Raspberry Pi 3 Model B]. Additionally, our {{pl|704|A-Star 32U4 Robot Controller with Raspberry Pi Bridge}} {{polpl|3116}} (which is an Arduino-compatible programmable module designed to be an auxiliary controller atop a Raspberry Pi or a stand-alone control solution on its own) has mounting hole locations as these Raspberry Pi boards.

Le châssis Romi dispose également de trou de montage destiné à la fixation du Raspberry Pi. Ces trous supporte le facteur de forme et trou de montage du Raspberry Pi A+, Raspberry Pi B+, Raspberry Pi 2 Model B et [https://shop.mchobby.be/fr/30-raspberry-pi-3 Raspberry Pi 3 Modèle B et suivants]. En plus, le {{pl|704|contrôleur robotique A-Star 32U4 Robot avec Pi Bridge de Pololu}} {{polpl|3116}} (qui est un module Arduino-compatible programmable conçu pour être un contrôleur auxiliaire ay dessus d'un Raspberry Pi -ou- une solution de contrôle autonome) dispose de trou de montage comme les cartes Raspberry Pi boards.

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.

De façon similaire, les trous de montages Romi pour Arduino, comme les trous de montages utilisés pour Raspberry Pi, sont sur des surfaces à des hauteurs différentes. Comme mentionné ci-avant, quelques entretoises <small>([https://www.pololu.com/category/93/spacers lien pololu])</small> peuvent être utilisées pour surélever la carte à une hauteur appropriée. Cependant, en utilisant un Raspberry-Pi, il y a réel avantage à suréleber un peu plus la carte de façon à avoir accès au port HDMI en enlevant simplement un moteur de son clip. Pour pouvoir faire cela, il faut surélever le Pi 15mm au dessus du compartiment pile. Cela peut être fait à l'aide de deux entretoises de 25mm (pour les trous de montage à l'avant) et deux entretoises de 15mm (pour l'arrière). A noter que l'usage de telles entretoises nécessitera des vis M2.5 plus longues.

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:
