Electrical Engineer Jenner Hanni (of OSH Park and Wickerbox Electronics) designed a protoboard DIP for the Next Thing Co. C.H.I.P. (“The World’s First Nine Dollar Computer”):

for when you need something more durable than a breadboard

The KiCad schematic and layout are available at the Github repo. The project is released as Open Hardware under the CERN Open Hardware v1.2 License.

This project was created using the CHIP DIP KiCad template from Wickerlib. The protoboard holes are connected where indicated by exposed copper, for easier wire routing and soldering.

Jenner has shared the board on OSH Park:

$17.50 for a set of three

For a non-stackable version, you can just use two standard 0.1” (2.54mm) pitch 1×40 headers, each snapped in half.

For a stackable version, you can use two of these extra-tall 2×20 female headers from Adafruit. The connectors are from the Samtec SSQ family so you could shop around for other distributors, but Adafruit has by far the best price for this particular component.
