Hardware

This site documents the physical side of the tag project: the circuit boards, the printed and machined parts they sit in, and the bench work that turns a fabricated board into a tag ready for a bird.

Section	Covers
Board Designs	KiCad designs for tags, bases, chargers and bench equipment, and how fabrication outputs are generated
Mechanical Designs	Printed cases, adapters and jigs, and the parametric model behind the tag cases
Board Assembly	Preparing a fabricated BitTag board: programming, labelling, battery, conformal coating

The project overview, the tag families and the field guides are on the project home. The host applications, firmware and command-line tools are documented in the software documentation.

Getting the designs

Everything here lives in the hardware repository. It builds on its own; you do not need the software repository to work on a board.

Fabrication outputs are generated from the design files rather than committed, so a board you want to order is a build away rather than a file to find.
