NOTE FOR PULL REQUESTS: I DO NOT ACCEPT MASS ADDS. If you have 5-6 really awesome parts, I'll accept a pull request, but if you have say 10+ parts, I will not. Select only the neatest. Also, make sure JLCPCB offers the parts, if they're intended for board mounting!

  • 8473.30 -> The board must be used in conjunction with a programmable machine (under HTS section 8471), in that it must meet the following requirements:
  1. Storing the processing program or programs and at least the data immediately necessary for the execution of the program.
  2. Being freely programmable in accordance with the requirements of the user.
  3. Performing arithmetical computations specified by the user AND
  4. Executing, without human intervention, a processing program which requires them to modify their exeuction, by logical decision during the processing run.

Also, another friend mentioned 8537.10.9170 is a common entry for general purpose circuit boards for controlling things. So may want to look into that if appropriate for your uses. Note: This has a 27% Tarriff at least in Oct, 2024

Questions

How big is the Etheraddon PCB?

It measures 38.7 × 40 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Etheraddon use?

37 parts, built around the LM5160ADNTR and MT2492. 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 Etheraddon KiCad files?

From the cnlohr/cnhardware repository on GitHub, at the commit this page was made from: the board is ch32v20x/ch32v208funboard/etheraddon/etheraddon.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Etheraddon design in my own project?

Its repository states no licence, so its author keeps all rights: ask cnlohr before reusing the design.
