About the Faultycat PCB

Faultycat is an open source RP2040/RP2350 PCB design by ElectronicCats, published on GitHub under the BSD-3-Clause license. It is a 2-layer board measuring 51.2 × 124.2 mm, with 94 components from 59 distinct parts.

Its main chip is the IRLML2502, from the RP2040/RP2350 family. Other key parts include the AP2112K-3.3, W25Q16JV, RP2040, TXS0108EPW and TLV75718PDBV. By type, the board carries 25 resistors, 24 capacitors, 11 connectors, 10 diodes, 7 transistors and 7 switches.

From the project

Faulty Cat is a low-cost Electromagnetic Fault Injection (EMFI) tool, designed specifically for self-study and hobbiest research.

Faulty Cat is a low-cost Electromagnetic Fault Injection (EMFI) tool, designed specifically for self-study and hobbiest research.

Faulty Cat is a high-end Electromagnetic Fault Injection (EMFI) tool a remix of the project ChipSHOUTER PicoEMP design optimization focused in rough order on (1) safe operation, (2) high performance, (3) usability, and finally (4) cost. This results in a tool that covers many use-cases, but may be overkill (and expensive) for many.

Faultycat: common questions

What microcontroller does the Faultycat use?

The Faultycat is built around the IRLML2502, from the RP2040/RP2350 family.

How big is the Faultycat PCB?

The Faultycat measures 51.2 × 124.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Faultycat?

94 components, from 59 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 Faultycat design files?

From the ElectronicCats/faultycat 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 Faultycat design in my own project?

Yes, under the terms of its BSD-3-Clause license, which ElectronicCats chose for the repository.

Can I test firmware for the Faultycat 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.
