About the NFC-Copy-Cat PCB

NFC-Copy-Cat is an open source Microchip SAM PCB design by ElectronicCats, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 40.4 × 43 mm, with 38 components from 27 distinct parts.

Its main chip is the ATSAMD21E18A, from the Microchip SAM family. Other key parts include the AP2112K-3.3TRG1, MCP73831-2-OT, TC4424 and GD25Q16C. By type, the board carries 8 capacitors, 7 resistors, 6 ICs, 6 connectors, 6 diodes and 4 switches.

It belongs with the power & battery designs in this gallery.

From the project

NFC Copy Cat is a small device that combines two powerful cybersecurity tools, NFCopy and MagSpoof. NFCopy works by reading or emulating a NFC card; depending on the necessities of the researcher.

NFC Copy Cat, manufactured by Electronic Cats, is a small device that combines two powerful cybersecurity tools, NFCopy and MagSpoof. NFCopy works by reading or emulating an NFC card; depending on the necessities of the researcher. On the other hand, MagSpoof can wirelessly emulate/spoof any magnetic stripe card. So using NFC Copy Cat, the user will have a device capable of storing magnetic stripe data or NFC payment data to be replayed later — known in the cybersecurity world as a replay attack.

NFC-Copy-Cat: common questions

What microcontroller does the NFC-Copy-Cat use?

The NFC-Copy-Cat is built around the ATSAMD21E18A, from the Microchip SAM family.

How big is the NFC-Copy-Cat PCB?

The NFC-Copy-Cat measures 40.4 × 43 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the NFC-Copy-Cat?

38 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the NFC-Copy-Cat design files?

From the ElectronicCats/NFC-Copy-Cat repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the NFC-Copy-Cat design in my own project?

Yes, under the terms of its GPL-3.0 license, which ElectronicCats chose for the repository.

Can I test firmware for the NFC-Copy-Cat without the hardware?

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