IcyBlue: common questions
What microcontroller does the IcyBlue use?
The IcyBlue is built around the ICE5LP4K-SG48ITR, from the FPGA family.
How big is the IcyBlue PCB?
The IcyBlue measures 50.8 × 22.8 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the IcyBlue?
73 components, from 34 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 IcyBlue design files?
From the Oak-Development-Technologies/IcyBlue repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the IcyBlue design in my own project?
Yes, under the terms of its MIT license, which Oak-Development-Technologies chose for the repository.
Can I test firmware for the IcyBlue 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.
