Zenith: common questions
What microcontroller does the Zenith use?
The Zenith is built around the XC7K70T-FBG676, from the FPGA family.
How big is the Zenith PCB?
The Zenith measures 194.1 × 141.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Zenith?
56 components, from 27 distinct parts. The full bill of materials is listed on this page.
Where can I download the Zenith design files?
From the kostareg/zenith repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Zenith design in my own project?
The repository has no license, so all rights stay with kostareg. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Zenith 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.
