Telefon: common questions

What microcontroller does the Telefon use?

The Telefon is built around the SC0692, from the Raspberry Pi family.

How big is the Telefon PCB?

The Telefon measures 140 × 70 mm, has 4 copper layers and is 1.2 mm thick.

How many components are on the Telefon?

1 components, from 1 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 Telefon design files?

From the ptulin/telefon repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Telefon design in my own project?

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

Can I test firmware for the Telefon without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
