We modified SparkFun's Artemis Module to use Ambiq's more capable Apollo 3 Blue Plus, giving us a pin-for-pin compatible module with all the existing features, but with twice the flash and RAM.

We also populated our module onto a SparkFun Redboard to create a dev board.

To validate the Artemis Plus design, a small batch of prototype modules were fabricated.  First, we had a panel of bare PCBs manufacturered.

Then we populated some with the Apollo 3 Blue Plus microcontroller and other necessary components.

Since this was our very first iteration of the Artemis Plus module, only a few of these boards were populated with components and then placed on SparkFun RedBoard Artemis ATP development kits.  Fortunately for us, the design worked properly on the very first try. We were able to verify all the pins (ATP) available on the module were wired correctly.

Our prototype modules on the RedBoard served as the platform to test the Arduino Board Support Packages, which needed to be updated to take advantage of the Apollo3 Blue Plus microcontroller. We are now able to seamlessly run code using the Arduino IDE. Artemis projects simply need to be recompiled to run on the Artemis Plus.

All of the hardware design files are open source.  The Artemis Plus was remixed from the SparkFun Artemis. All of the hardware design files are distributed in accordance with the terms of the Attribution-ShareAlike 4.0 International License (http://creativecommons.org/licenses/by-sa/4.0/), which are the licensing terms used by the original SparkFun Artemis.

While the original Artemis Module design files were made in EAGLE, for this remix, they have been imported into Altium Designer.

We hope to be able to do mass manufacturing to make modules and dev kits affordable and available.
