PatchLogic: common questions

What microcontroller does the PatchLogic use?

The PatchLogic is built around the LFE5U-85F-8BG381x, from the FPGA family.

How many components are on the PatchLogic?

28 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the PatchLogic design files?

From the Unicamp-Odhin/PatchLogic repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the PatchLogic design in my own project?

Yes, under the terms of its CERN-OHL-P-2.0 license, which Unicamp-Odhin chose for the repository.

Can I test firmware for the PatchLogic 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.
