SN-64: common questions

What microcontroller does the SN-64 use?

The SN-64 is built around the LFE5U-85F-6BG381C, from the FPGA family.

How big is the SN-64 PCB?

The SN-64 measures 101.8 × 80.5 mm, has 6 copper layers and is 1.2 mm thick.

How many components are on the SN-64?

383 components, from 117 distinct parts. The full bill of materials is listed on this page.

Where can I download the SN-64 design files?

From the FantomZap/SN-64 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the SN-64 design in my own project?

The repository has no license, so all rights stay with FantomZap. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the SN-64 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.
