Flipper Add-On: Ethernet
Turn your Flipper Zero into a wired-network auditor: scan, spoof-test, and sniff Ethernet LANs you are authorized to access.
$25.00
In stock
- Wired Ethernet / LAN networks (10BASE-T)
- LLDP-enabled switches, routers, access points & servers (via Passive Discovery)
- Wireshark (for deep PCAP analysis)
In the box
Flipper Add-On Ethernet board (no Ethernet cable)
Not included
Neither the Ethernet (RJ45) cable nor the Flipper Zero itself ship in the box.
You also need
A Flipper Zero (sold separately) and an Ethernet (RJ45) cable connected to an active network — the cable is not included.
- Designed and built in Aguascalientes, Mexico
- Hardware CERN-OHL v1.2 · firmware GPL-3.0
Map a wired network before you touch it
On a network you own or have explicit permission to test, run ARP Scanner to see what’s live and Passive Discovery to spot LLDP-enabled switches, routers, access points, and servers without sending a single probe — then dig deeper with the Port Scanner and OS Detector.
Prove a LAN is vulnerable to ARP spoofing
Run the ARP Spoofing tool on a network you own or have explicit permission to test, capture the traffic with the built-in Packet Sniffer, then export it as PCAP and open it in Wireshark for a deeper look.
Run wired-network exercises in a workshop or CTF
Install the app in minutes: download the latest release, connect the Flipper via qFlipper (or Flipper Lab / the mobile app), and upload the .fap through the File Manager’s Apps folder — then let students run ARP scanning, spoofing, and passive LLDP discovery on a network built for the exercise, always with explicit permission.
Start in 10 minutes
- Go to the GitHub Releases page of the firmware app repo and download the latest .fap file.
- Connect the Flipper to qFlipper, Flipper Lab, or the Flipper mobile app (with Experimental Options enabled).
- In the File Manager, navigate to the Apps folder.
- Upload the .fap file to the preferred folder inside Apps (any folder works, e.g. Misc).
| Ethernet Controller | Microchip ENC28J60 |
|---|---|
| Ethernet Standard | 10BASE-T |
| Duplex Mode | Half duplex, Full duplex |
| SPI Bus Speed | Up to 20 MHz |
| Connector | Flipper Zero external GPIO port |
| SPI Pin Mapping | MOSI = PA7 (pin 2), MISO = PA6 (pin 3), CS = PA4 (pin 4), SCK = PB3 (pin 5) |
| Interrupt Pin | ENC28J60 /INT on pin 10 (PA14, shared with SWCLK) |
| Cable | Not included — requires a standard RJ45 Ethernet cable connected to an active network |
| Power | Powered from the Flipper Zero's GPIO 3V3/GND pins |
| Onboard MCU | None — driven directly by the Flipper Zero's own STM32WB55 MCU over the SPI bus |
| Packet Buffer | 8 KB on-chip SRAM (3 KB RX ring, 1.5 KB TX ring) |
I need a case for my board.
Not for this board yet: the 3D-printable STL case files in the flipper-addons repo currently cover the Marauder, SubGHz and MagSpoof add-ons only. There is no published case file for the Ethernet add-on.
My question is not here!
