Fis: common questions

What microcontroller does the Fis use?

The Fis is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the Fis PCB?

The Fis measures 106.7 × 69.1 mm, has 2 copper layers and is 1.6002 mm thick.

How many components are on the Fis?

41 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the Fis design files?

From the nicolasfara/fis repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Fis design in my own project?

Yes, under the terms of its GPL-3.0 license, which nicolasfara chose for the repository.

Can I test firmware for the Fis without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
