I've always preferred to build prototypes using "solderable breadboard" style prototyping board, which has holes tied together in groups of 3-4 - but quality prototyping board like this has been hard to find at a reasonable price. This 4"x4" size is the largest size of prototyping board that I offer (see below for links to smaller versions). All of these are manufactured on high quality 1.6mm thick FR4 material with lead-free HASL surface treatment, double-sided with plated through holes. Compare to other prototyping board around the internet, which is often made on low quality single-sided phenolic resin with no surface treatment in the copper - we wouldn't use that garbage in our projects, and neither should you!
The 4" x 4" board has a ground trace around the outside, crossing the board in three places, and three independent power rails next to the ground rails.
Sometimes you need a ground plane. For projects like that, we now offer an enhanced 4-layer version with a ground and power plane. In these boards, all ground stripes are tied to the ground plane, and the three power rails are all tied to the power plane (ie, they are not independent).

International orders have been suffering long delays due to COVID-19 - please check your country at https://about.usps.com/newsroom/service-alerts/international/ and make sure that I can ship to you, and that you are okay with any delays. There may be additional information available from your national postal service. Some customers have reported packages being delayed in transit by over a month. We cannot offer any sort of guarantees regarding international shipments at this time; we apologize for the inconvenience, and are looking into shipping internationally through UPS.
Please be sure that the address given to Tindie is accurate, and includes your street name and number - company name is only required if shipping to a commercial address. International orders require a valid phone number.
Domestic packages that go more than 1 week without a tracking update will be presumed lost in the mail and refunded or reshipped as buyer prefers. Any international packages can be delayed in customs without warning for 2 weeks or more. After 1 month without a tracking event (2 months to South and Central America - insane delays in those nations are commonplace), we will reship or refund a missing order (as you prefer). COVID-19 update: Some countries have stopped processing incoming international mail entirely -we will cancel orders to countries which we know are not processing international mail at all. This may also cause longer than usual shipping times - we are not responsible for such delays.
We do not open inquiries through the postal service - experience has shown this to be futile.
We ship all orders via USPS. UPS will be added as an option in the near future!
