Here's some updates on the new board(s).

The form factor will change. The current prototype is significantly smaller (6.5cm x 4.5cm). There are more IO pins (100 completely unused) on the Artix 7 version and the connectors have changed to some high-density surface mount connectors.

The main reason for this is the cost of shields. Assembly for the thru-hole stackable headers is really expensive and where most of the cost comes from on the simpler boards. It's basically impossible to make a shield cost less that $25. The new form factor will help with this.

There will be an adapter board available that will make it possible to use your existing shields.

A protoboard that breaks out all the IO to 0.1" holes will also be available.

The Mojo V3 and ISE will continue to be supported for the foreseeable future. With that said, some new features may be impossible to bring to the Mojo for technical reasons. Supporting ISE is actually easy from the point of view of the Mojo IDE since it's frozen. The only real challenge is getting all the emails from people who can't get it to build because of Windows 10.

The new Artix 7 based board doesn't have official pricing yet, but I'm hoping to get it around $99.

This board, will be overkill for most people beginning and difficult to swallow at that price point. This is why it isn't the only board we are working on. We have another board in the works based on the iCE40 using the same form factor (but less IO). The hope is to make a board around $50 with open-source and proprietary tool-chain support.

There isn't a current ETA for these. The move to the new site and some other behind the scenes projects are taking my current attention, but I do have a working prototype on my desk. The current work is in validating some software can work with it as I want and getting a prototype of the Lattice board.

Thank you for the update.

Have you considered putting a Pmod connector on the new boards?

It's handy for easily attaching all sorts of things, for example Ethernet, SD card reader, GPS, PS/2, RTC etc. Plus it's a simple enough spec that it's relatively easy for people to create their own Pmods. I understand you have your shields, but this would be great for those smaller, simpler, add-ons.

There definitely won't be a pmod connector on the board as their pin density is terrible. However, we could make a shield with some on it if there's enough interest.

About the Vivado software: Is there a free licence for Vivado just like for ISE Webpack?
As I understand it, there is a free version "Vivado HL WebPACK Edition", ... bpack.html, it doesn't support Spartan-6, but Spartan-7 and Artix-7 and more, so Mojo v3 is not supported.

I have a background as a software engineer (in a previous life), so my main interest is the different languages, so for me is the most important thing with Vivaldo is that it supports SystemVerilog.

Any new information on the ETA for the new board? I will be first in the queue to buy it...

No firm ETA yet but check out or for updates!
