Raspberry Pi CM3L Single Board Handheld

We apologize for not posting any updates recently. Summer was quite busy for us. We are currently working on v4.1 of the boards.

This revision will address the following:

- Battery charging circuit issues

- Button locations and sizes

- Add audio out

- Add HDMI out

Here is a teaser of what the new case design is looking like!

We will try to be better about posting more frequent updates. Check us out on Instagram to see more day to day progress!

We've also been slowly working on a case design! Here is a picture of the early prototype.

This version will incorporate the HDMI out and the audio out. Also should fix the issues with the battery circuit.

The most recent version of the board has been assembled and tested! There has been a design flaw identified with the load sharing feature of the battery management circuit but otherwise the board is a success. The next version will fix the battery management and add audio and HDMI out capabilities.

We have ordered the new boards and already have all of the required components. Hopefully we can get the boards put together ASAP. In the meantime we have begun work on the case design.

I have made a blank Kicad project that has all the parts necessary for jumpstarting a project based on the Raspberry Pi Compute Module 3 Lite. All of the files are available at our GitHub. If anyone has an issue using these files, please let us know so we can help fix any issues.

The process of designing v4.0 of the board has begun. We have chosen to modify the design slightly with this update. This update will also bring the battery management circuit onto the board, a power switch, and buttons that are better suited for manufacturing. This version will also add test points and holes for mounting the device in a case. Here is quick look at the proposed board redesign:

The first prototype is complete. There are some minor issues with the layout and some features that still have yet to be added. The next version of the board is in the works and should be closer to the final version.
