Ice40-dip40: common questions

What microcontroller does the Ice40-dip40 use?

The Ice40-dip40 is built around the ICE40UP5K-SG48I, from the FPGA family.

How big is the Ice40-dip40 PCB?

The Ice40-dip40 measures 17.8 × 50.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Ice40-dip40?

46 components, from 24 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 Ice40-dip40 design files?

From the esynr3z/ice40-dip40 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Ice40-dip40 design in my own project?

The repository has no license, so all rights stay with esynr3z. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Ice40-dip40 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.
