Flipper Zero - Portable Multi-Tool Device for Geeks - Fully Open-Source & Customizable - RFID + NFC Reader, Infrared Remote and Wireless Signal Explorer for Curious Minds, White

Flipper Zero is one of those rare gadgets that feels like it was made for geeks by geeks. It’s wireless, pocket-sized, and packed with tools - RFID, sub-GHz, infrared, GPIO, and more. All wrapped in a playful dolphin-themed interface. Whether you’re testing remotes, cloning access cards, or exploring signal protocols, it’s endlessly useful and surprisingly intuitive. The community support and open-source ecosystem make it even better. Highly recommended if you love tinkering, learning, and pushing boundaries - just be ready to lose hours exploring what it can do. And remember, keep it legal!

This is a great little tool. Put off grabbing one for a while. Sounded cool but I thought it was just something for low effort peoples to speed run some sense of accomplishment. In the end grabbed one to have one, before they got banned or something silly. Seeing the gpio pins clinched it as figured at worst it was an overpriced usb to uart bridge, that I could flash a couple led's with. Searched for some vids before it arrived, and read a bunch of complaints about how it couldn't open cars or wouldn't pick up a dogs tag. I saw some positive comments but nothing that really communicated the full potential. Finally got the thing and pretty instantly grew to love it. Would have been amazing to have this as a young teen, aside from being a cool educational tool that encourages you to explore outside your interests just to see the lil dolphin get a bit more experience. Way beyond that, it is a legitimate swiss army knife for some hardware hacking, in the classical sense. The number of uncased AVRdudes or old serial cables lying about, flipper can do it all. AVR flasher, ESP32 programmer, SWD debugger, I2C bus scanner. If there's not "an app for that", you can write your own, give it some nice graphics that are integrated with the overall aesthetic and build against whichever firmware you are using. The support for that is fleshed out, full of examples, with a healthy dev community. It's not brain dead it is C (headers are defined for easy compilation with C++), but there is a lot of support for people learning. - Look for Derek Jamison, on youtube (has a bunch of dev tutorials for fz) Dev experience is smooth, with a python tool for target building only your app, generating a `.fap` that you are then able to simply drag and drop onto the sd card to instantly see on your flipper. In this way it acts as a microcontroller that can save your gpio experiments to be easily replayed later without reflashing. There are some pretty high effort apps made by the community. With official devs and friends putting out things like the AVR flasher, which you can download from the flipper "app store" or from github and build. Didn't get any expansion boards when I purchased, and stuck with the official firmware (or modifying the official firmware) just to really explore what it could do in stock form. But it is worth mentioning that like with the dev community there are builders making physical expansion cartridges. There's a bunch of unofficial firmware's, some are just compilations of community apps and data dumps, but others lift limitations to free the hardware. It's one of those one's that you can really go down a rabbit hole with. This is a tool like Vim is a tool.

I wasn’t sure what to expect from the Flipper Zero, but one thing’s for sure: it’s not your average gadget. This tiny powerhouse combines the fun of a digital pet with the thrill of a high-tech Swiss Army knife. And yes, there’s a dolphin that levels up the more you use it. It’s like having a tiny tech buddy egging you on with every new discovery. This isn’t just a tool, it’s a ticket to a world of exploration. Whether it’s talking to RFID, NFC, or even infrared, the Flipper opens up so many possibilities that it’s hard to resist trying it on everything around the house. One minute, you’re pressing buttons, and the next, you’re feeling like a secret agent who just unlocked a hidden skillset. It’s compact, portable, and perfect for satisfying your tech curiosity. Plus, there’s something addictive about leveling up that little dolphin every time you find something new to scan or test. Now, if you’re new to tech, you might need to watch a YouTube tutorial or two, but let’s be real: if you’re reading this review, you probably already know what it’s capable of and just want to join in on the fun. And if you’re already in the know, the Flipper’s learning curve won’t be a problem—it’ll be part of the fun. The only real downside? It can go through battery life pretty fast if you’re playing around a lot. But honestly, that’s a small price to pay for what it offers: hours of entertainment, endless curiosity, and a dolphin buddy who’s always there to “high-five” your latest tech feat. The Flipper Zero is equal parts gadget, game, and guilty pleasure, worth every penny and then some. Just be prepared to spend a little more time poking around than you planned!

You really have to learn this product but great gadget

The Flipper Zero has a number of features that make it a powerful tool for interacting with access control systems. These features include: * A built-in antenna that can read and write RFID and NFC tags * A built-in infrared transceiver that can be used to emulate radio remotes * A built-in iButton reader that can be used to read and write iButton keys * A built-in GPIO interface that can be used to connect to other devices The Flipper Zero can be used to: * Read and emulate RFID and NFC tags: This can be used to open doors, access computers, and pay for items. * Emulate radio remotes: This can be used to control garage doors, TVs, and other devices. * Read and write iButton keys: This can be used to access buildings and other secure areas. * Connect to other devices: This can be used to control lights, appliances, and other devices. My favourite being my work passes and 2FA. I have all my 2FA information saved on my Flipper Zero and also my Work Pass to get through security. Brilliant piece of equipment, not a waste of money in my eyes.

This was way smaller than I expected - fits into your palm. Really well made - feels solid and the buttons have a satisfying click to them. It's got a cute sort of dolphin based interface ( when you turn it off the dolphin weeps ). That said this is a very technical tool - it can do endless things and has been well supported but I needed to update the firmware from the get go to have it work. It scans some cards and not others - there are forums to help here but you need to be familiar with smart card standards to debug stuff.

Absolutely love this product one of the best things I have ever bought came perfectly fast and just amazing service

Easy to learn. There's tons of instructions and information on the Internet. I can now control my digital radio my skybox my smart TV my air-conditioning at work and get into the building without my key foband read my Pets microchips and also annoy my kids by ringing my doorbell
