KiCanvas: View KiCad Files in a Browser
KiCanvas by Thea Flowers is an open-source, interactive, browser-based viewer for KiCAD schematics and boards. Not only can you view files from your computer or GitHub links, but it is also designed to be embedded in a web page so you can use it to directly reference your KiCAD files in online documentation. The embed-ability greatly simplifies documentation management since it saves the hassle of exporting images after every revision. - kicanvas.org and GitHub. Via LinkedIn.

New Boards Supported by CircuitPython
The number of supported microcontrollers and Single Board Computers (SBC) grows every week. This section outlines which boards have been included in CircuitPython or added to CircuitPython.org.
This week there were (#/no) new boards added:
Note: For non-Adafruit boards, please use the support forums of the board manufacturer for assistance, as Adafruit does not have the hardware to assist in troubleshooting.
Looking to add a new board to CircuitPython? It's highly encouraged! Adafruit has four guides to help you do so:
- How to Add a New Board to CircuitPython
- How to add a New Board to the circuitpython.org website
- Adding a Single Board Computer to PlatformDetect for Blinka
- Adding a Single Board Computer to Blinka
New Learn Guides
The Adafruit Learning System has over 3,200 free guides for learning skills and building projects including using Python.
Fruit Jam OS is under heavy development by the community. If you'd like to participate, check out the Adafruit Discord, YouTube and GitHub. Via X.

CircuitPython Libraries
The CircuitPython library numbers are continually increasing, while existing ones continue to be updated. Here we provide library numbers and updates!
To get the latest Adafruit libraries, download the Adafruit CircuitPython Library Bundle. To get the latest community contributed libraries, download the CircuitPython Community Bundle.
If you'd like to contribute to the CircuitPython project on the Python side of things, the libraries are a great place to start. Check out the CircuitPython.org Contributing page. If you're interested in reviewing, check out Open Pull Requests. If you'd like to contribute code or documentation, check out Open Issues. We have a guide on contributing to CircuitPython with Git and GitHub, and you can find us in the #help-with-circuitpython and #circuitpython-dev channels on the Adafruit Discord.
You can check out this list of all the Adafruit CircuitPython libraries and drivers available.
The current number of CircuitPython libraries is ###!

Tim
This week I wrote a few of the guide pages for the NeoPot poroduct guide. I've also been continuing to review many PRs submitted by the community with improvements to Fruit Jam OS and the apps within it. I worked on simplifying the volume API in the Fruit Jam library as well since the DAC supports so many different ways to control volume. We put a customizable limit mechanism in it as well to try to help prevent small speakers from getting blown out.
