FTUno: common questions

What microcontroller does the FTUno use?

The FTUno is built around the ATmega328P-A, from the AVR/Arduino family.

How big is the FTUno PCB?

The FTUno measures 68.6 × 53.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the FTUno?

52 components, from 34 distinct parts. The full bill of materials is listed on this page.

Where can I download the FTUno design files?

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

Can I use the FTUno design in my own project?

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

Can I test firmware for the FTUno without the hardware?

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