Questions

How big is the CollabJam PCB?

It measures 57.6 × 40.4 mm and has 4 copper layers, 1.5 mm thick.

What parts does the CollabJam use?

65 parts, built around the TCA9548ARGER. 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.

Where can I download the CollabJam KiCad files?

From the TactileVision/CollabJam-PCB repository on GitHub, at the commit this page was made from: the board is v4/CollabJam.kicad_pcb and its schematic v1/CollabJam.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the CollabJam design in my own project?

Its repository states no licence, so its author keeps all rights: ask TactileVision before reusing the design.
