In my last post I figured out the battery mounting solution. The next step is to get the Raspberry Pi mounted and powered.

Mounting the Raspberry Pi

As mentioned in this post, I’m using openGrid for a flexible mounting solution. I designed this simple raspberry pi opengrid snap mount in fusion

The advantage of this opengrid setup is the existing ecosystem of parts. For example, this cable holder.

Power Distribution

The external battery is a TalentCell 12V, 6A battery. This of course needs to be stepped down using a buck converter.

The final amount of wiring looks like the following.

Next Steps

ROS 2 and remote teleop.
