Fmcw: common questions
What microcontroller does the Fmcw use?
The Fmcw is built around the XC7A15T-FTG256, from the FPGA family.
How big is the Fmcw PCB?
The Fmcw measures 118.6 × 83.2 mm, has 4 copper layers and is 1.6002 mm thick.
How many components are on the Fmcw?
432 components, from 117 distinct parts. The full bill of materials is listed on this page.
Where can I download the Fmcw design files?
From the matthuszagh/fmcw repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Fmcw design in my own project?
Yes, under the terms of its Apache-2.0 license, which matthuszagh chose for the repository.
Can I test firmware for the Fmcw 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.
