ICE40hxk4 dev board: common questions
What microcontroller does the ICE40hxk4 dev board use?
The ICE40hxk4 dev board is built around the iCE40-HX4K-TQ144, from the FPGA family.
How big is the ICE40hxk4 dev board?
The ICE40hxk4 dev board measures 67 × 157 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the ICE40hxk4 dev board?
379 components, from 73 distinct parts. The full bill of materials is listed on this page.
Where can I download the ICE40hxk4 dev board design files?
From the smartbench/mainboard repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the ICE40hxk4 dev board design in my own project?
The repository has no license, so all rights stay with smartbench. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ICE40hxk4 dev board 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.
