Balise tofs: common questions

What microcontroller does the Balise tofs use?

The Balise tofs is built around the RASPBERRYPIZERO2, from the Raspberry Pi family.

How big is the Balise tofs PCB?

The Balise tofs measures 95.4 × 95.4 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Balise tofs?

97 components, from 37 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 Balise tofs design files?

From the EsialRobotik/Electronique 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 Balise tofs design in my own project?

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

Can I test firmware for the Balise tofs 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.
