This repository contains a collection of various adapter board designs created by Piotr Esden-Tempski and 1BitSquared.
All the designs are available under the Creative Commons V4.0 By Attribution Share Alike license.
You are welcome to take the designs and order your own boards or order them prebuilt from 1BitSquared US or 1BitSquared Germany/EU. Each adapter board README file should contain a link to an OSHPark order link. You can then easily order the boards in multiples of 3 with free international shipping. :)
If you have some additional adapters or modify the published desings and you would like to share with us and the community through this collection please do not hesitate to send us a pull request. The only hard requirement is that the designs are done in KiCad. Thank you for your support!
Please DO NOT use the adapter designs to create your own and unmodified retail products. You are not helping anyone besides your own pocket by making "cheap copies". We are sharing those designs to be helpful to the community not for you to make a quick buck. :D
If you are interested in bulk pricing to resell the adapters through your own shop please contact: info@1bitsquared.com we do provide good bulk pricing for anyone who wants to carry our products.

It measures 20 × 15.5 mm and has 2 copper layers, 1.6 mm thick.
70 parts. 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.
From the 1bitsquared/1b2-adapter-collection repository on GitHub, at the commit this page was made from: the board is pmod_jtag/v1.0/pmod_jtag.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask 1bitsquared before reusing the design.
