Installing Empyrean Support in Arduino IDE
- Open the Arduino IDE and then navigate to the Preferences screen by selecting the
Filemenu, and thenPreferences. Click the small button to the right of the text box labeledAdditional Boards Manager URLs, and then paste the following URL into the windows which pops up: https://github.com/etherkit/ArduinoBoards/raw/master/package_etherkit_index.json
Click OK to close this window, and then OK to close the Preferences. - Navigate to the Arduino Boards Manager in the IDE by selecting the
Toolsmenu, thenBoard, and thenBoards Manager.... In the search box in the upper right of the Boards Manager windows, typeSAMD. - In the search results list below, find the entry for
Arduino SAMD Boards, select it with your mouse, and then click the install button. - Next, find the entry for
Etherkit SAMD Boards, select it, and click the install button. Close the Boards Manager window when this is complete. - In the
Tools > Boardsmenu, you should now see Empyrean Alpha and Empyrean Beta listed as board options. Select the appropriate board in order to start uploading sketches to your Empyrean.
USB-UART (CDC) and Other Serial
You can access the built-in USB-UART (virtual serial port) by using the SerialUSB object in your sketch, just as you use Serial in AVR-powered Arduinos. You can also use pins 0 and 1 of Empyrean as a hardware serial port with the Serial1 object.

Questions
How big is the Empyrean PCB?
It measures 18.3 × 45.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Empyrean use?
46 parts, built around the CG0603MLC-05E, DMG1012T-7 and ECS-.327-12.5-34B-TR. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Empyrean KiCad files?
From the etherkit/Empyrean repository on GitHub, at the commit this page was made from: the board is pcb/Empyrean.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Empyrean design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
