Icezum: common questions
What microcontroller does the Icezum use?
The Icezum is built around the iCE40HX1K-TQ144, from the FPGA family.
How big is the Icezum PCB?
The Icezum measures 68.6 × 53.3 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Icezum?
208 components, from 74 distinct parts. The full bill of materials is listed on this page.
Where can I download the Icezum design files?
From the FPGAwars/icezum repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Icezum design in my own project?
Yes, under the terms of its GPL-3.0 license, which FPGAwars chose for the repository.
Can I test firmware for the Icezum 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.
