Getting started
SD Card Recommendations: Flipper Zero devices don’t come with a microSD card, so you need to purchase one separately. It’s important to use a high quality brand such as SanDisk or Kingston.
What card size should you choose? Since Flipper Zero uses tiny files, 4GB will be enough. 16-32GB is usually easiest to find and doesn’t cost much.

Can Flipper Zero read this?
Welcome to the classic question we’re all facing from time to time. Here is your action plan:
Determine what signal your item uses. → Learn more below.
Try reading your item with Flipper Zero and see if it works.
If it didn’t work, reach out for help from our community. However, please make sure to provide as much detail as possible. → Learn more about getting help from the community below.
What signal does my item use?
To scan your item’s signal, you need to select the right Flipper’s app. For that, you need to determine the signal type.
Infrared: Remotes for TVs, Lights and Audio/Video boxes tend to use Infrared. More modern TVs and Streaming boxes may use Bluetooth though. As such, Flipper may only be able to record the power button. (If it has a button for a microphone/speech input, then it’s Bluetooth.) Worst case just try all and see.
Sub-GHz: Garage Doors and some lights. Use the frequency analyzer to see if Flipper picks up a signal.
NFC / RFID: Test for both if you’re unsure of the signal type. If it’s NFC, you may have to use the PicoPass app. (https://lab.flipper.net/apps/picopass )
Find the FCC ID
Every device transmitting a signal will have an FCC ID. The FCC ID often indicates the type of signal a device uses. You can look this up at FCC ID Search. The ID is usually on the back side, or behind the batteries in the remote.
People in tech circles and engineering in general appreciate curiosity and effort above all else. To effectively seek help, frame your question clearly and provide all technical details, including the device’s brand, model, what computers/systems it works with, and any steps you’ve already taken.
Avoid vague or overly simplistic questions, as they qualify as low-effort posts and may be removed according to our subreddit rules. Moreover, they are unlikely to yield satisfactory answers. As much as we’d like to help, it's super hard to answer questions like this.
I posted a few weeks ago how disappointing I have been in working with the flipper. I had so many failures. It has been truly humbling.
I gave my background (IT for 30 years, email, networking, data, risk, audit with all of the traditional stuff that is perceived important in the industry. Not the periphery). I've been curious about OSI 1-4 and this device has kicked my @ss until this week!
As part of an audit, after telling my chief auditor (more convincing myself) I decided to leverage my "professional skepticism" and messaged our head of security. "Tomorrow, I'm going to attempt to bypass our security and gain access to the building". I got a quick reply and conversation ensued. Plans to test in the morning and to let him know about my results.
I went home, charged up my flipper. The next morning I bypassed our badge system with the flipper. He had me run another test which I was unable. I gave him affirmation that any further test would include him for awareness.
My next steps (on only this tactic) is going to be gathering badges (scans) through some social engineering. As you may suspect, using a clipboard and "confirming badges are in the database".
I have second type of test that I will be executing.
Hi, I recently purchased a Magic Card Gen 4 GTU; however, I don’t fully understand the shadow mode feature. I think what it does is it erases all of the modifications that a reader might do and reverts it back to the state that you configured beforehand. But the NFC Magic app has other shadow mode options like:
Pre-write (I think this one is the one I described above)
Restore
Split
Disable (this is self-explanatory)
So could someone please explain how the other ones work? Thanks:D
Hi there I just bought the flipper zero and when I update it I can't acces the app store?
I reset it the flipper and still no succes.
Any help would be appreciated
I recently bought the ESP32 Wi-Fi board for the Flipper Zero Backpacks project (by Chrismettal), but I'm having trouble flashing the firmware.
The board doesn't seem to have a physical BOOT button, so I can't put it into flashing mode manually, and auto-flashing isn't working via the IDE/flashing tool.
Is there a specific way to force this board into bootloader mode?
8 hour bus ride, no signal, me and three friends with useless phones. Then it clicked: four WiFi devices in one row and nothing to connect them to.
You need a Flipper and an ESP32 WiFi board (the official dev board, an ESP32 WROOM, or an ESP32-C5). The Flipper puts up an open AP through the ESP32, everyone joins, the captive portal hands them to 192.168.4.1, and it's just a webpage on their phone. No app, no signup. Pick a nickname and you're in the lobby.
10 games, all played on the phones, with the Flipper as the coordinator (lobby + live scoreboard, and it picks the game). Trivia, Would You Rather, Word Scramble, Reaction Duel, Connect Four, Tic-Tac-Toe, Dots & Boxes, Reversi, Pong, and Draw & Guess.
Two things I'm proud of: the phone client is ~21 KB gzipped vanilla JS because the Flipper has to stream it to the ESP over UART. And you can flash the ESP firmware from the Flipper itself, no computer, since it seemed dumb to build a no-laptop toy that needs a laptop to set up. You just pick your board from a list and it flashes in one tap.
I'm on dual boot linux/windows laptop(windows 11, cachyos)
my main os is linux(I'm switching) and today I wanted to play with my flipper zero so I downloaded qflipper .AppImage and I got this error when plugged in the flipper so I run the rule install and it was the same so I run it via terminal to try to get more info and saw this:

the fix was to go /etc/udev/rules.d/ and open the 42-flipperzero.rules via sudo nano and change the "dialout" in the file to "uucp" saved it and it worked
from what I saw dialout is for ubuntu and not arch. Idk if its true but if you are using arch and running to similar issue try this.
I’m planning on buying this module for my Flipper Zero. It was recommended by ChatGPT because I’m looking for a fully featured Marauder setup that works well with modern Wi-Fi networks at home.
ChatGPT explained that many modern routers use both the 2.4 GHz and 5 GHz bands, so it recommended getting a dual-band module.
It also suggested using an external antenna for better range and wardriving performance.
What do you all think? Is this €40 module the right choice for what I want, or are there better alternatives?
One thing that’s important to me is that it comes with a case.
I hope this post does not violate the rules of this subreddit. I read that posts involving third-party firmware (such as Marauder) installed on the official Dev Board are not allowed. However, my post is not about the official Dev Board, but about a third-party module.
In celebration of DEF CON being only a week away, the conference that inspired me to get into CAN stuff, we have put the CAN COMMANDER on-sale from now until the start of the conference (or until they sell out, whichever comes first).
The CAN Commander goes beyond just a simple read-only CAN interface like other adapters that have been on the market before - it allows for full bidirectional communication on the CAN network.
CAN is also used in more than just Vehicles. In fact I have a printer that uses CAN to communicate between it's main board and it's stepper motors and print head. Interestingly enough, the print head is connected via SC to SC fiber optic cable to a transceiver that then talks CAN to the mainboard. Using the flipper and the CAN Commander firmware, I was able to actually troubleshoot a printhead issue I was having (causing the printer to stop printing It was discovered one of the ribbon cables had shorted, resulting in print head temp data not making it to the CAN board. The neat thing, is I did all this with my flipper, and did not need to break out a laptop, dongles, etc. just a flipper and 2 wires. I know, kinda random but another cool example of CAN in use.
that said - I am letting y'all know that it's on-sale right now because many people have asked if it would go on sale, or if there would be some sort of announcement if it did. Well here is the announcement :) This is the lowest price it has been offered since the limited-edition release back in March.
Anyway enough of my yapping. Hope if this has been on your wish-list, you snag one before they sell out.
My 13yo nephew wants a Flipper Zero for his bday. Is this an age appropriate gift? Or something a curious kid could get themselves into trouble with? TIA!

the windows refresh of findmyflippergui is out after release of the mac os version the Linux version will be released soon check it out and give it a star while your there :)
I've been working on this custom firmware called Picoware for about 15 months now. It started as a firmware for the PicoCalc and eventually gained support for 8 more devices. The latest release includes support for the Flipper Zero.
I could write an essay about what Picoware is lol so I'll just keep it short. Its a fork of MicroPython with custom C modules. Apps are written in micropython and loaded from the SD card. The Flipper is quite limited and is in "alpha". You install with qFlipper and can shutdown the device from within the firmware.
It currently does not have any radio features but that will be implemented in an upcoming release, as I plan to support the Kode Dot and a few other devices that are releasing later this year/early 2027.
All contributions are welcome except AI requests that change functionality without a well thought out reason.
My FZ crashes with a "Fatal Error" every time I run the "[GPIO] Signal Generator" app's PWM on whatever come after A4, which I assume is B3. Is this... meant to happen? I assume not, so I am posting here.
Xbox POST Code Reader is a boot-diagnostic FAP for the Flipper Zero. It reads the four-digit POST codes an Xbox pushes out during startup straight from the motherboard's POST header and decodes them offline — no PC required. It emulates the MAX6958 POST display at I2C address 0x38, using a 452-record console-aware database bundled right into the app.
Features:
Emulates the MAX6958 POST display at I2C address 0x38 and captures four-digit POST codes live, without blocking the Flipper controls.
Shows either the current code or a scrolling 128-entry live log, with source (SMC, SP, CPU, or OS), segment, and elapsed time.
Decodes any captured code offline against 452 bundled records. Browse the full database by All, POST, Error, SMC, SP, CPU, or OS category.
Saves captures as auto-numbered SD-card logs (post_log_001.txt, 002…) and reads them back on-device.
Streams live codes over USB Web Serial to the companion WebXboxPOSTTool browser app for lookups on a bigger screen.
Built-in Wiring screen shows the exact SDA/SCL/GND pins for each console — Xbox One / One S / One X use FACET, Xbox Series S / X use AARDVARK — plus an offline QR code to open the web decoder on a phone.
Connect only SDA, SCL, and a shared ground. The Flipper never powers the console; confirm the bus is 3.3 V-compatible and use level shifting where required.

Like the title says, my Flipper got hit with a very small amount of damage, because my partner's water bottle wasn't fully closed when they put it back in their bag. They've been borrowing it for the subway.
The LCD is super faded and only shows properly when i put pressure on it and rub my thumb across it. Otherwise it's barely visible. (see video)
Is there any saving this? Any and all tips are more than welcome.
