FD2: common questions
What microcontroller does the FD2 use?
The FD2 is built around the XC7A100T-FGG484, from the FPGA family.
How big is the FD2 PCB?
The FD2 measures 112 × 158 mm, has 4 copper layers and is 1.2 mm thick.
How many components are on the FD2?
263 components, from 69 distinct parts. The full bill of materials is listed on this page.
Where can I download the FD2 design files?
From the Jegeva/FuzzyDuck repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the FD2 design in my own project?
The repository has no license, so all rights stay with Jegeva. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the FD2 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug FPGA firmware against it before you order a PCB.
