Piunora

By now all of the beta testers have received their units and have been playing with the board. I already got some valuable insight into software issues.
In the meantime I was hustling to secure the stock for all the parts which was quite nerve wrecking due to many parts being out of stock for many months. In the end I found enough drop-in replacements so at least this first production run is secured!

I have also been busy making all the last changes that I discovered since the last production prototype. Mostly silkscreen fixes and a few pin out changes (the pins that normally over a UART on Arduinos now actually has pins with hardware UART).

I also sneaked in a little bonus feature for the adventurous hackers. You can now optionally mount a SIM card connector to use 4G/5G modem cards in the M.2 connector. I verified that this is actually possible, in this case you just need to close the USB jumper that I provided to re-route the USB-A port to the M.2 connector.

Piunora has been in development for about 3 months now and has moved on to the pre-production run, if no issues arrive from that I will also release the design files. I know some are eager to take a look at those but I had bad experience with releasing unfinished designs so I'm sticking to verified designs.
Once they are ready for release I will create a GitHub repo and add it to this project. So if you follow this project you should be notified about the release.

I've been meaning to track the development on hackaday.io but it was just way to taxing to do this also besides actually working on it but I try to give you some of the background details after the fact to give you an idea how the development had progressed.
Now the design is entering more the production phase and I hope I can give you more insights into that as it progresses.

Piunora has entered its crowdfunding campaign yesterday on CrowdSupply and I'm really happy about all the excitement I have received throughout the day!

If you are eager to get a Piunora the campaign is your best bet, it will receive boards first before any other distributors after the campaign.
