Mini ice40: common questions

What microcontroller does the Mini ice40 use?

The Mini ice40 is built around the ICE40HX1K-VQ100, from the FPGA family.

How big is the Mini ice40 PCB?

The Mini ice40 measures 25.4 × 43.2 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Mini ice40?

33 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mini ice40 design files?

From the hacklabmikkeli/mini_ice40 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Mini ice40 design in my own project?

Yes, under the terms of its LGPL-3.0 license, which hacklabmikkeli chose for the repository.

Can I test firmware for the Mini ice40 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.
