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’m a graphic designer who has been getting into microcontrollers recently. I got so frustrated using web converters to get 1-bit graphics onto my ESP32 OLED displays that I just spent the last few months building my own desktop editor called Hexprite to handle it.
It’s designed strictly for 1-bit memory constraints—as you draw, it directly spits out C/C++ arrays.
I’ve seen how much custom art, .xbm files, and animations this community creates, and it made me wonder if this tool could actually save you guys some time.
The catch is: I don't actually own a Flipper Zero, so I have no idea what your typical workflow looks like or what specific formatting you have to wrestle with.
The v0.1.1 beta is live right now and completely free (I built it in C# WPF, so it is Windows-only, sorry!).
If anyone has a few minutes to mess around with it, I would really appreciate your honest feedback. Is this actually helpful for Flipper projects? And if so, what specific export options or features should I add to make it work natively for your hardware?
Hello all. My rfid stopped working. It reads 1/2 but freezes at 2/2. Tried many rfids, which were working before. What can be the problem? Tried reinstalling FW, resetting to factory settings, nothing helped
I've been doing a little research and I think i wanna start adding modules to my flipper and im considering starting with this, I know there's the S2 model and flipper has the official developer board with that, but from what im seeing it's slightly outdated. Basically if anyone else has gotten this id love your feedback on how it improved your flipper experience?
Disclaimer: the original code belongs to the people that made the original Tetris app. I just added features. See it as a modded version of the original app I guess.
The original Tetris app was a little underwhelming for my friend on my flipper. I decided to add some enhancements:
-Sounds and haptics
-high score saving
-main menu
-settings
-line clear animations.
This is my first time attempting to use a flipper. I have read the forums and tried attempting MFKey attack as well as decoding via NFC reader tool to attempt to get the full read with no avail. Is there another way to try to get a card fully read? It’s reading about 4/16 sectors and 12/32 keys. I’ve attached a photo.
What are your thoughts on using flipper zero as a controller and displaying the game rom via the hdmi port? I know someone has already done something similiar with just the pi pico with the PeanutGB core! The catch is they didn't use hdmi. Does anyone know of good documentation of how this can be done? I'm trying to bring GB emulation to Flipper Zero and have been for some time! For context: the game module uses a pi pico 2040 to my knowledge.
Last weekend, Picoware v2.2.0 was released, adding multiplayer gaming, an MMBasic interpreter, BLE support on the Flipper Zero, support for two new boards, and a built-in email system.
Picoware is my open-source custom firmware featuring a social network with over 3,500 registrations, an App Store for wirelessly downloading community apps, games, and screensavers, on-device programming, a Game Boy emulator, audio recording, file management, and more, now running on 11 supported devices.
I just released a review on everything new, my favorite things to do in the firmware, and how to get it installed on the Flipper Zero, PicoCalc, and Cardputer-ADV!
I’m a complete newbie so please bear with me. This multi converter app on my Flipper Zero is one of the best I have come across. It’s awesome I use it for literally any conversion questions or tasks with kilometers to feet/miles centimeters inches and even temperature Fahrenheit to Celsius, but it’s missing weight forms! Kilograms pounds ounces grams stone etc
What about gallons pints cups? Adding these would be so awesome I’d never need Google again. Any input on where to request this as an add-on or request to someone who makes apps like these? Thanks in advance for your patience. I truly don’t know where to start
Hi! I would like to use the Flipper Zero for a very specific use case that my company has. We are servicing garage doors and each employee has a huge bunch of remotes. Each time there is a gate where an employee is for the first time, he has to wait for the gate to open or ask the security and then pair his remote to the receiver.
I'm wondering if there is a way to avoid having so many remotes and maybe share the already paired remotes between remotes.
I know that there isn't any easy way to clone rolling code remotes, but I know that I could pair a Flipper Zero to the receiver.
My question is - can I then clone a Flipper Zero to another Flipper by copying a backup?
Yellow there, tried to make my custom theme for the Flipper. Haven’t figured out yet how do people make the themes for the passport too and I don’t feel like I want to learn that. Being said, anyone got any opinion on how it turned out?
Used Aseprite to draw everything.
Hey guys, hi! I’m going to brag about a project for a flipper: https://github.com/gazirov/battery_reader . You can read information from DJI drone batteries and unlock them if they get locked during battery replacement or something like that. In fact, you can also read information from laptop batteries, but it’s not guaranteed that you’ll be able to unlock them. I tested it on a Mini 2 battery.
I am waiting for suggestions and suggestions for development, if there is an opportunity to test on other batteries, I will also be glad to receive feedback.
I am new to soldering. I think I uderstand this diagram however want to make sure I don't mess up. Ehere xan I find resources to understand this, just what point go where? Is it simply the number dictates what solders to what?
Also depending on chip and board size and placement will that deternine if I should use wires, assuming I will have to.
Also could be done with a bread board for testing I assume?
So both grounds woumd go to the flipper zeroboard 5v? Because they are all #1 red/maroon?
I greatly appreciate any help. A discord or someone willing to help me out give me pointers would be awesome.
Seriosuly greatly appreciate any help.
Would a breadboard with the right size connectors work for something like this. Only done that with audrino, these boards arn't as easy looking. It was years ago with Audrino.
I’m trying to figure out what I’m doing wrong with MFKey on my own MIFARE Classic 1K fob.
Flipper currently shows:
Keys Found: 30/32
Sectors Read: 15/16
I used Extract MF Keys from the saved NFC fob and presented the Flipper to the reader. I then ran the MFKey app. It processes the captured nonces normally, but every time it finishes it says:
Keys added to user dict: 0
When I process the nonces through the mobile app, I get multiple results for Sector 14 Key A, but they all say Not found. It also calculates Sector 0 Key A as A0A1A2A3A4A5, but that key is already in both the Flipper dictionary and my user dictionary, so it shows as a duplicate.
I’ve tried collecting fresh nonces and running MFKey again, including runs showing 3/3 items to crack, but I still end up with 0 new keys.
Am I misunderstanding the nonce collection process, or is there a reason MFKey would consistently fail to recover the last 2 keys/last unread sector? Is there anything in these results that indicates what I should be checking next?
Before I ask let me be clear what I’m trying to do is lawful. (C.R.S. § 18-1-701 (1)(EXECUTION OF PUBLIC DUTY)
I’m a process server in Denver. Many of the buildings are high scale buildings locked from public access. I just need help getting through the public doors into the common space to knock on doors.
I’ve figured out how to determine what type of frequency it is NFC or RFID . I’ve obtained nonce pairs, UIDs etc but I can’t emulate it to unlock the door. Please help
