A Tamagotchi for Hackers — With Serious Credentials
Flipper Zero was conceived by Russian engineers Alex Kulagin and Pavel Zhovner in 2019, inspired by earlier projects like the Pwnagotchi Wi-Fi auditing device. Their goal was different though: a single portable device that could interact with the full range of digital access systems and radio protocols that surround us in daily life — keycards, garage remotes, infrared signals, NFC tags — all from something that fits in your pocket and looks like a toy.
The Kickstarter campaign launched on 30 July 2020 with a modest goal of $60,000. It raised $1 million in the first 24 hours. By the end of the campaign, 37,987 backers had pledged $4,882,784 — exceeding the goal by over 8,000%. First units shipped to backers in 2022. An official App Store launched in July 2023. In February 2024, the Video Game Module — a Raspberry Pi RP2040-based add-on with VGA output — was released officially. The device has now sold globally and built one of the most active open-source hardware communities on the internet.
Where the dolphin comes in
- Flipper Zero features a pixel-art dolphin virtual pet as its core UI character
- The dolphin evolves as you use the device — more exploration, happier dolphin
- This gamification makes security concepts approachable for beginners
- The dolphin’s mood reflects the device’s status and usage patterns
What’s Actually Inside This Thing?
Flipper Zero is deceptively compact — 100 × 40 × 25 mm and 102 grams — but contains a surprisingly sophisticated hardware stack built across four interconnected PCBs. The core is the STM32WB55 dual-core ARM microcontroller: a 64 MHz Cortex-M4 running the main firmware, and a 32 MHz Cortex-M0 dedicated to Bluetooth Low Energy 5.4. A dedicated NFC PCB (STM ST25R3916 chip), a separate Infrared/iButton PCB, and a dual-band RFID antenna board round out the hardware.
| Specification | Detail |
|---|---|
| Processor | STM32WB55RG — Dual-core ARM Cortex-M4 @ 64 MHz + Cortex-M0 @ 32 MHz |
| RAM | 256 KB |
| Flash | 1 MB internal + MicroSD up to 256 GB |
| Display | 1.4-inch monochrome LCD, 128 × 64 px, orange backlight |
| Battery | 2,100 mAh LiPo — up to 28 days standby |
| Connectivity | USB-C, Bluetooth LE 5.4, Sub-GHz radio (CC1101), NFC, RFID, IR, iButton |
| Inputs | 5-position D-pad + back button |
| GPIO | 18-pin header for hardware expansion |
| Dimensions | 100 × 40 × 25 mm / 102 g |
| Firmware | Open-source (GPLv3), written in C — active community forks |
| Official Price | $169 USD — flipperzero.one |
Note: the battery is 2,100 mAh — some earlier sources incorrectly listed 2,000 mAh. The corrected figure is confirmed on the official Flipper product page.
Seven Ways Flipper Zero Talks to the World
Flipper Zero’s defining feature is its ability to interact with the invisible digital signals that surround us. From your office access card to the garage door remote to the TV remote you lost down the sofa — Flipper can read, store, replay, and emulate a remarkable range of protocols.
Expanding Beyond the Box
Flipper Zero ships with the device itself, a USB-C to USB-A cable, a quick-start guide, and a sticker. A microSD card is required but not included — 16–32 GB from a reputable brand is recommended. Flipper officially cautions against cheap no-name cards as many do not support the SPI mode the device uses. Several official accessories extend functionality significantly.
Where Flipper Zero Really Comes Alive
Out of the box, Flipper Zero is useful. With the community behind it, it becomes a completely different beast. The official App Store launched in July 2023 allows users to install new tools, games, and experimental apps directly from the Flipper Mobile App on iOS or Android. Firmware is updated actively — bi-weekly stable releases via qFlipper desktop software.
Beyond the official firmware, a thriving ecosystem of community forks has emerged. Momentum is currently the most actively maintained alternative firmware (forked from Xtreme, which ceased development in November 2024). It offers improved customisation, better battery management, and expanded app support while maintaining update integrity via signed releases.
What the community has built
- Momentum firmware — improved menus, battery charge capping, expanded app library
- Custom Sub-GHz signal databases covering thousands of devices
- Expanded NFC libraries for newer card types
- Hardware add-ons: Wi-Fi boards, nRF24 transceivers, Geiger counters
- Games, Pomodoro timers, Flappy Bird — the dolphin has a social life
- r/flipperzero and dedicated Discord with active daily development discussion
The Honest Conversation About Misuse
What the headlines got wrong — and what’s actually true
In early 2024, Canada’s government proposed banning Flipper Zero, claiming it facilitated car theft. In March 2024, Queensland Police in Australia raised similar concerns. These claims were widely shared — and largely inaccurate.
The reality: Modern vehicles use rolling-code protocols and two-way authentication. Flipper Zero’s official firmware supports capture and replay of fixed-code signals from older or legacy devices — but cannot bypass the KeeLoq successors or advanced encryption used by modern cars. As of 2024, no verified incidents of vehicle theft using Flipper Zero have been documented. Security researchers and Flipper’s own developers have publicly addressed and rebutted these claims.
That said, the device can be misused for RFID skimming of older cards, Bluetooth device spamming, or unauthorised replay of fixed-code systems. This is why ethical and legal use is essential — and why this article is framed as educational.
Legitimate uses that Flipper Zero excels at
- Penetration testing access control systems — with proper authorisation
- Auditing your own home or office RFID badge security
- Replacing multiple TV remotes with one learned IR device
- Learning about radio protocols, NFC, and digital systems hands-on
- Electronics prototyping and GPIO hardware development
- Security research in a controlled lab environment
