A Flipper Zero (sold separately), plus a USB magstripe card reader connected to a computer to read the track data of any card you want to emulate through its MagSpoof half.

What is Marauder + MagSpoof?

Flipper Add-On: Marauder + MagSpoof combines the same ESP32 Marauder WiFi/Bluetooth analysis board sold on its own as the Marauder add-on with Electronic Cats’ MagSpoof, its magnetic-stripe card emulator, on a single board for the Flipper Zero. The module ships with Marauder firmware factory-loaded, ready for WiFi and Bluetooth frame capture, device enumeration and frame transmission. MagSpoof emulates a magnetic-stripe card wirelessly: a TC4424 driver chip amplifies pulses from the Flipper Zero into a coil, generating an electromagnetic field that mimics swiping a card through standard magstripe readers, no physical swipe needed, for authorized security audits. Where the standalone Marauder add-on covers WiFi/Bluetooth testing alone, this variant adds that wireless magstripe emulation without swapping boards.

Turn a capture into evidence you can open in Wireshark

You have finished a session on networks and devices you are authorized to test, and the report needs packet-level proof, not a summary. Connect the add-on to Marauder UI Pro in Chrome or Edge, then use the Storage Manager to pull the session’s .pcap, .log and .json files straight off the device’s SPIFFS/SD storage. Open the .pcap in Wireshark and cite exact frames.

Work from your phone when there is no laptop on site

On site for an engagement you are authorized to run, with only a phone in your pocket. Android browsers do not support Web Serial, so the browser dashboard is out; the Marauder UI Pro Android Edition talks to the add-on over a USB OTG cable instead. One step comes first: there is no pre-built APK, so you build the app from source with Node.js and Android Studio.

Test whether a magstripe reader accepts an emulated card

You’re running an authorized audit of a reader that accepts magnetic-stripe cards — a payment terminal, an access-control panel, a transit gate. Read the test card’s track data with a USB magstripe reader, save it to a .mag file on the Flipper Zero’s SD card, then open the MagSpoof app and send it: a TC4424 driver chip turns the Flipper Zero’s pulses into an electromagnetic field that mimics a swipe, no physical card contact needed. Basic transmission has been confirmed working against an MSR90 reader.

Start in 10 minutes

Prepare the Flipper Zero: flash a firmware whose API version matches the add-on apps. Electronic Cats recommends Unleashed Firmware. Use qFlipper (the official desktop tool) or the official Flipper mobile app: connect over USB, choose "Install from file", then Install.
Install the Marauder UI Pro dashboard’s dependencies: with Node.js in place, run npm install in the project folder.
Launch it with npm run dev — or skip the local setup entirely and open the hosted demo.
Open the dashboard in Chrome or Edge, click Connect, and select the ESP32 Marauder device’s COM port (Web Serial API).

What's the difference between Marauder and Marauder Spoof?

Both start from the same ESP32 Marauder WiFi/Bluetooth board, factory-loaded with Marauder firmware. Flipper Add-On: Marauder is that board on its own. Flipper Add-On: Marauder + MagSpoof combines it with Electronic Cats’ MagSpoof: a TC4424 driver chip and coil that emulate a magnetic-stripe card wirelessly, no physical swipe needed, for authorized security audits. Basic transmission has been confirmed working against an MSR90 reader.

What is Marauder firmware?

Marauder firmware — short for ESP32 Marauder — is the upstream project created by the independent developer justcallmekoko. Electronic Cats does not develop or maintain it; it builds the software around it, such as the Marauder UI Pro dashboard. Do not confuse it with your Flipper Zero’s own firmware: that one is the official build, Unleashed or a custom build, and it only has to match the API version the add-on apps were compiled with.

I need a case for my board.

The flipper-addons repository ships 3D-printable STL case files in its case/ folder, and Marauder is one of the add-ons currently covered, alongside SubGHz and MagSpoof. Download the STL that matches your board from github.com/ElectronicCats/flipper-addons, print it, and you are done — no need to design an enclosure yourself.

I don't have a Flipper Zero. Is there a standalone option?

Yes. This add-on needs a Flipper Zero to run. If you want a self-contained tool, look at Minino, an Electronic Cats board with its own screen, buttons and preloaded firmware: it covers 2.4 GHz WiFi and Bluetooth Low Energy analysis, adds Zigbee/Thread sniffing, an onboard GPS for wardriving and a microSD slot for captures, and runs on 3x AAA batteries. It does not run the Marauder firmware, so if the Marauder toolset itself is what you need, stay with this add-on. Minino: https://electroniccats.com/store/minino/
