Dongle: common questions

How big is the Dongle PCB?

The Dongle measures 29.7 × 21.2 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Dongle?

11 components, from 10 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Dongle design files?

From the andrewo3/pangotag-pcb repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Dongle design in my own project?

The repository has no license, so all rights stay with andrewo3. Use it as a reference, and ask the author before reusing the design.
