The KiCad project lives in the Serhio4522/SEM_hitachi- repository on GitHub; these links point at the commit this page was built from.
SEM hitachi-: common questions
What microcontroller does the SEM hitachi- use?
The SEM hitachi- is built around the LFE5U-25F-6TG144C, from the FPGA family.
How big is the SEM hitachi- PCB?
The SEM hitachi- measures 100 × 70 mm, has 4 copper layers and is 1.6062 mm thick.
How many components are on the SEM hitachi-?
284 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 SEM hitachi- design files?
From the Serhio4522/SEM_hitachi- 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 SEM hitachi- design in my own project?
The repository has no license, so all rights stay with Serhio4522. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the SEM hitachi- 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.
