IcE1usb panel: common questions

What microcontroller does the IcE1usb panel use?

The IcE1usb panel is built around the ICE40UP5K-SG48, from the FPGA family.

How big is the IcE1usb panel PCB?

The IcE1usb panel measures 100 × 132.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the IcE1usb panel?

116 components, from 40 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 IcE1usb panel design files?

From the osmocom/osmo-e1-hardware repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the IcE1usb panel design in my own project?

The repository has no license, so all rights stay with osmocom. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the IcE1usb panel 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.
