NEDOCON was born in 2009 as online store for electronic kits and boards based on free designs created by nedoPC community since 2002. Actual sales started in 2011 and then NEDOCON became part of TERNARY RESEARCH CORPORATION - a New York corporation incorporated in 2012 and operated by founder of nedoPC community, professional software developer Alexander "Shaos" Shabarshin (MSCS'96 and electronic hobbyist since 1985) and his wife Olga (professional graphic designer) - both are strong free software supporters with many years of GNU/Linux and MacOS X experience. All hardware designs listed here are absoultely FREE and pretty much "hobbyist friendly" because only through hole components are used in most of them! Company also offers some services as custom software development for listed devices and custom hardware modifications of those devices - it costs less than you can imagine!

We have free delivery for U.S. customers (foreign customers should contact us before purchase, but usually PCB delivery is free worldwide). Orders are normally prepared and shipped within five business days. If user bought something else in that period of time then we will combine all purchases in one package. Typically you should get your kits in 2 weeks, but it could be longer because of the postage delays or customs (for some foreign countries you may expect about two months). Foreign customers are responsible for their taxes, import duties or any other customs related charges (phone number is required for them in order to include it in custom form along with the address). If you need 10 or more identical items then we may offer some discounts (contact us for this). If you need to receive your order faster then you need to buy "express delivery option" ("Pay Now" button below). It is PRIORITY EXPRESS service from USPS - 1 or 2 business days for U.S. or 1 week worldwide (package will be trackable and insured). Also express delivery option is not refundable in case of return (see below).

TERNARY RESEARCH CORPORATION is authorized to collect sales taxes for NY residents, so please contact as first if you are New York State resident with your full shipping address and we will send you PayPal invoice with included sales tax with specific rate (it depends on actual street address, not only zip-code) otherwise your payment will be immediately refunded.


You may return items for full refund within 30 days after delivery even if you already opened a kit and started soldering, but you need to return all components of the kit or we will reduce your refund amount. Also you need to pay shipping costs to deliver returning kit back to us. Sometimes we may refund your shipping costs also for example in case of our mistake or defective components. We will NOT refund payments for express delivery.
