Hermes-Lite 2.0: common questions
What microcontroller does the Hermes-Lite 2.0 use?
The Hermes-Lite 2.0 is built around the EP4CE22E22C8N, from the FPGA family.
How big is the Hermes-Lite 2.0 PCB?
The Hermes-Lite 2.0 measures 100 × 100 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Hermes-Lite 2.0?
488 components, from 114 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 Hermes-Lite 2.0 design files?
From the softerhardware/Hermes-Lite2 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Hermes-Lite 2.0 design in my own project?
The repository has no license, so all rights stay with softerhardware. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Hermes-Lite 2.0 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.
