Ossc: common questions
What microcontroller does the Ossc use?
The Ossc is built around the EP4CE15E22C8N, from the FPGA family.
How big is the Ossc PCB?
The Ossc measures 124.6 × 68.8 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Ossc?
259 components, from 72 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 Ossc design files?
From the marqs85/ossc_pcb 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 Ossc design in my own project?
The repository has no license, so all rights stay with marqs85. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Ossc 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.
