Flipper Devices has officially introduced the Flipper One open-source hardware portable Arm Linux platform and networking and Edge AI multi-tool powered by a Rockchip RK3576 octa-core Arm Cortex-A72/A53 SoC, and featuring a Raspberry Pi RP2350 for low-level control.
You may think of it as a successor to the popular STM32-based Flipper Zero hardware and wireless hacking tool, but the company stresses that the Flipper One is NOT a replacement for the Flipper Zero. It is a different product with mainline Linux kernel support, no binary blobs (probably not 100% true), and open-source drivers, and operating at a different level of the networking and wireless stacks with dual Gigabit Ethernet, Wi-Fi 6E, and optional 5G or 4G LTE modem.

Flipper Devices partnered with Collabora software development company for the upstreaming work for the Rockchip RK3576 to make sure the Flipper One supports “full mainline Linux kernel with no binary blobs, no proprietary drivers, and no vendor-locked board support package”. Some claims may be hard to meet, notably because the bootloader usually requires a closed-source binary blob for the RAM initialization (but an open-source alternative is being worked on), and more importantly, the firmware for WiFi and cellular is usually closed-source for regulatory (e.g., FCC) compliance.
Development is still in progress, and Flipper Devices welcomes users to contribute through the Developer Portal, containing information about hardware, firmware, Linux (Debian-based Flipper OS), UI using FlipCTL framework, testing, and documentation. It also includes task trackers, architectural discussions, and a live status of mainline Linux support. Finally, you’ll find several Flipper One-related repositories for the Linux build scripts, RP2350 MCU firmware, and more on GitHub.
Overall, the Flipper One will be a highly versatile, modular, open-source hardware and software Linux platform with networking and Edge AI capability. I’m using the future tense because the company is not quite ready to take orders at this time and will announce developer hardware availability, pricing, and consumer release timing in a future update.
