New v3.1.7 Batch Arriving

Hello all, We very much appreciate the patience of everyone who’ve been waiting for their ULX3S! Short update here, just to let you know we have shipped a new batch to Mouser. We also have some news on the progress of ULX4M and a preview of the new Synth project we've been working on. Read the full update.

Slowly Approaching v3.1.7

Hi to all! Sorry about the update delay - but we are trying to figure out our options for the next batch. Current situation is that we have 100 85F chips and all parts, but we are in the middle of a new version. You already know everything about chip shortages, so I will just say it is almost impossible to get anything. Due to the low quantity of boards (that have already been pre-ordered), we will move the next delivery date to November. Read the full update.

Production Delays for New Batch

It's been a long time since my last update, and I have some not-so-great news about the new batch of ULX3S boards. As you may have heard, supply chains are not in good shape right now. We did managed to get all of the components for a new batch...except for the Lattice 85F FPGA. Our most recent news about that suggests that more will be available in four to six weeks. After that, we'll need some time to produce and ship the boards, so we've pushed our shipping estimate back to June 1st. But we also have some good news! Read on to learn more about our plans to design a more modular FPGA board. Read the full update.

Our Shipment Has Finally Arrived at Mouser's Warehouse

Hi everybody. We lost a couple of weeks due to customs-related issues, but everything has come through in the end. Mouser has received the shipment at their warehouse and will begin sorting it all out this week. We've pushed the estimated ship date back to October 12th, but we expect crowdfunding orders to be on their way before that. You have all been awesomely patient with these fulfillment delays. Thank you! Please check the 'Order Details' in your Crowd Supply Account Settings to make sure your shipping address is up-to-date! This post also covers our ongoing production plans, including our pick-and-place experimentation. Read the full update.

Almost There

More happy news from Intergalaktik!!! As of 28th August, our first batch—which includes 788 ULX3S boards and 200 PMOD sets—is on its way to Mouser for fulfillment. It will cover all crowdfunding orders and all current pre-orders. This update also describes some issues we've been having with our pick-and-place machine (but don't worry, it's a story with a happy ending). Read the full update.

All Boxed Up!

Just a quick update to let you know that all crowdfunded ULX3S boards (and all PMODs) were packed into ten boxes, last week, and are currently waiting on Mouser to initiate the pick up. This shipment will also include all current pre-orders and enough stock to cover expected sales while we are waiting on the second manufacturing run. Everything should be on its way to Mouser early next week, and we expect crowdfunding orders to ship out to backers by the middle of September. Pre-orders will follow shortly after that.

Now With Support for SynthoWheel Retro Sound!

We have reconstructed a vintage organ in the digital interface of ULX3S. With this simulation of a very famous vintage organ's tonewheel, our lab member EMARD created a polyphonic synthesizer with parameters that are configurable through a MIDI interface. Read the full update.

Ready for Crowdfunding

After many months of preparation, the team here at Radiona is ready to launch our crowdfunding campaign for the ULX3S FPGA with ESP32. Hackaday described ULX3S as creating "the Year of the Hacker FPGA," and we are finally ready to make that prediction a reality. Many people have worked to prepare this board – and the sample code that highlights its potential – for distribution to makers and hobbyists worldwide. We believe this is one of the best developer boards ever designed, as it incorporates a vast array of features and capabilities into one relatively small and reasonably priced package.
