Lfi rig: common questions

What microcontroller does the Lfi rig use?

The Lfi rig is built around the Pico, from the RP2040/RP2350 family.

How big is the Lfi rig PCB?

The Lfi rig measures 130 × 95 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Lfi rig?

13 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the Lfi rig design files?

From the fraktalcyber/lfi-rig repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Lfi rig design in my own project?

Yes, under the terms of its MIT license, which fraktalcyber chose for the repository.

Can I test firmware for the Lfi rig without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
