Floppy-Ant-Controller: common questions
What microcontroller does the Floppy-Ant-Controller use?
The Floppy-Ant-Controller is built around the STM32F072CBT6, from the STM32 family.
How big is the Floppy-Ant-Controller PCB?
The Floppy-Ant-Controller measures 65 × 60 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Floppy-Ant-Controller?
53 components, from 28 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 Floppy-Ant-Controller design files?
From the FloppyO1/Floppy-Ant-Controller 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 Floppy-Ant-Controller design in my own project?
Yes, under the terms of its CERN-OHL-S-2.0 license, which FloppyO1 chose for the repository.
Can I test firmware for the Floppy-Ant-Controller without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
