PCBs for sale

Note: These designs are NOT for beginners. You will need, at the minimum, some prior experience in soldering and assembly, and preferably the ability to read schematic diagrams, as pertinent information is given in them. There are no parts supplied with these boards. They are NOT kits. Elby Designs offers kits for some of these designs.

The printed circuit boards as listed below are available from me as indicated.

These boards are professionally etched, with component overlay and solder mask. All holes have been drilled. Most boards have smooth milled edges.
Note: Some of the older boards are NOT lead free / ROHS compliant. New boards and restocks are all made to RoHS requirements using either ENIG -Electroless Nickle/Immersion Gold- or Lead-free HASL - Hot Air Solder Leveling.

Please email me (otherunicorn@gmail.com) to organize the sale or enquire about availability.

Some boards marked as discontinued may be revived if there is sufficient interest. These runout boards are listed in orange.

Yes. Shipping is US$20.

By placing an order you accept these terms:

  • Items are sent by uninsured, untracked air-mail. If you require insurance, please specify when you email me. Insurance will cost $20 dollars or more, depending on the total order value. Some destinations are not insurable - e.g. Canada and Germany - due to the policies of the respective countries.
  • Any customs fees or taxes that the purchase attracts are the sole responsibility of the purchaser. If such fees or taxes are required, you will be contacted by the taxing body. It has nothing whatsoever to do with me. It is up to the purchaser to determine what can legally be imported into their country.
  • I am not responsible for uninsured boards that are lost in the postal system.
  • All sales are final. I do not take returns because "you have changed your mind".
  • I will accept changes to an order before it is shipped.
  • I will reply to your payment notification. If you do not get a reply to that email address within a couple days of payment, please email me. Note that I often won't reply on weekends.
  • Customs inspectors can read the prices on this web site just as easily as you can. Don't ask me to declare a false value; it is a crime for me to do so.
  • All orders are shipped from Australia.


I accept payment via PayPal. Please send payments to otherunicorn@gmail.com

Make sure you select GOODS or ONLINE PURCHASE payment type. Personal payments (no fee) will be rejected.

All prices are in US dollars.

Occasionally some of these boards are left-overs from prototype runs, and have minor faults. These faults are outlined in the appropriate construction articles.

I reserve the right to refuse to sell these boards on occasions I see fit.
