When you post, please add #CircuitPython2022 and email to let us know about your post so we can blog it up here.
Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. It should also work with most “full-size” Arduino clones, such as the EMSL Diavolino and the Seeed Studios Seeeduino, as well as the Netduino boards.Īs 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. The new UNO boards added a fourth mounting hole, which is indicated. The drawing has dimensions for both the regular Arduino and the Arduino MEGA, and the hole pattern is good for all Arduinos going back to the NG (though the diameter of the holes might be different). There’s a 1-inch scale mark next to the title block in case you want to verify that it printed correctly.
Somewhere in the Acrobat print dialog there’s going to be a “Page Scaling” option. In order to get it to print 1:1, you have to turn off print scaling in Adobe Acrobat. If you don’t have a proper punch, you can just use a sharpened nail (we’re not fancy here). I’d recommend you use the punch rather than just drilling through the paper, to avoid a “walking” drill bit. It is drawn at a scale of 1:1 on a standard 8.5×11 sheet, so you can print it out, lay the drawing down on your mounting surface, and use a pre-drill punch directly on the paper. You can use it as a reference to the dimensions or as a drilling guide. I figured others could use a similar drawing - after some polishing up, I had this Arduino hole dimension drawing (PDF).
In the process of working on a robot project, I needed to draw up an Arduino hole pattern and outline in CAD as part of the design. If all you have is a ruler and a pencil, this isn’t the easiest thing to do. While there are some great enclosures specifically designed for an Arduino, if you just have a regular box that you want to use, you have to measure and mark out the holes yourself. Arduinos are great, but if you’ve ever tried to mount one on a baseplate or inside an enclosure, you know it can be a pain.
