Ice40hx8k bg121 Breakout: common questions

What microcontroller does the Ice40hx8k bg121 Breakout use?

The Ice40hx8k bg121 Breakout is built around the iCE40HX8K-BG121(121-Ball_caBGA), from the FPGA family.

How big is the Ice40hx8k bg121 Breakout?

The Ice40hx8k bg121 Breakout measures 22.9 × 48.3 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Ice40hx8k bg121 Breakout?

55 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the Ice40hx8k bg121 Breakout design files?

From the jkiv/kicad-breakouts repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Ice40hx8k bg121 Breakout design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Ice40hx8k bg121 Breakout 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.
