- Require Elixir 1.10 or later. Previous versions probably work, but won’t be supported. This opens up the possibility of using Elixir 1.10+ features in future releases.

Spotlight: Pinout
If you've ever been doing Nerves and cursed yourself for closing the docs that had the pinout of the board, this library is for you. I had totally missed it.

Run Pinout.print() at your IEx prompt and get:
Very cool :)
Community updates
@pojiro shares his year with Nerves
It has been a while since I shared something from the Nerves JP community. They seem active still but I have a hard time following along over the language barrier :)
The post summarizes a lot of activity and you can get it translated by Google or in the original Japanese.
Nerves Meetup on 25th of January
The next event is about Control Systems and LiveView and features guest Powell Kinney. Double-check from your own device as Meetup can be tricksy with timezones, so you don't miss it.
Keep an eye on the Meetup page for updates.
Supporting the Nerves project
We want to encourage everyone to contribute in whatever way works for them. Here are some ways we currently recommend:
- Write or port a new hardware library and include it in the Elixir Circuits collection.
- Give money to the project via Open Collective.
- Get in touch about taking over maintenance duties for some libraries, we might be able to provide you hardware.
- Apply for an EEF stipend on something Nerves-related and build it. We can help if you have questions about this.
- Send corrections or improvements for documentation wherever it fails to help you.
- Write about Nerves, give talks about Nerves. Make videos about Nerves. It is all good.
Finally, if you have questions about the newsletter or want to suggest something you can simply respond to this email it will go directly to me, Lars, who edits this thing. Let me know what you think.
