Gerber Files

The Gerber files will be made available by request for use under the terms of the Creative Commons 3.0 sa-nc-by license.  Under the terms of the license, you are free to make boards for your own use or to make boards for commercial use as a component in a larger system.  You are not allowed to make and sell TAP-28 bare boards or assembled boards.

TAP-28 boards are offered here at a fair price that is cheaper than they can be commercially made in small quantities.  We are able to offer this price by making a large quantity of boards.  The boards are offered here as a service to the PIC user community.

Documentation For the Original Version of the TAP-28

The original version of the TAP-28 board differs only in a few details from Revision A and is equally useful for PIC applications.
