Overview

Zforce air adapter is an open-source printed circuit board by corytodd, from the corytodd/neonode-adapter repository on GitHub, published under the CC-BY-SA-4.0 licence. It is a 2-layer board of 39.9 × 16.5 mm with 10 parts on 15 nets, routed with 97 tracks and 12 vias.

It is built around the SM07B-GHS-TB. Its parts include 5 resistors, 3 connectors and 1 switch. It belongs with the interfaces and adapters boards of this library.

This is an alternative form-factor USB/I2C adapter board. The original board uses a flat-flex cable and FPC connectors. I've ripped up more traces than I care to admit... so I've made my own.

The idea is to use a single board design with the FPC on the backside that acts as the mount. The USB micro has been replaced by a USB C connector. The surface test points have been replaced by a JST header.

This is a work-in-progress. Parts are arriving in the next couple weeks.

Questions

How big is the Zforce air adapter PCB?

It measures 39.9 × 16.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Zforce air adapter use?

10 parts, built around the SM07B-GHS-TB. 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 Zforce air adapter KiCad files?

From the corytodd/neonode-adapter repository on GitHub, at the commit this page was made from: the board is zforce_air_adapter.kicad_pcb and its schematic zforce_air_adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Zforce air adapter design in my own project?

Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
