Flipper One is a handheld Linux hacker device built around Rockchip RK3576, 8GB LPDDR5, dual Gigabit Ethernet, and an M.2 Key B expansion port.
Key Takeaways
Main SoC is RK3576: 4x Cortex-A72 + 4x Cortex-A53 up to 2.2 GHz, Mali G52 MC3 GPU, 6 TOPS NPU.
Co-processor is RP2350B: dual Cortex-M33 + dual RISC-V Hazard3 at 150 MHz, handling low-power and hardware I/O tasks.
Ports include 2x USB-C (USB 3.1, one with DisplayPort 1.4 Alt Mode), 1x USB-A, HDMI 2.1 (4K@120Hz), 2x Gigabit Ethernet, 3.5mm TRRS, MicroSD, Nano SIM.
M.2 Key B slot (2242/3042/3052, PCIe 2.1x1, USB 3.1, SATA3, SIM passthrough) enables modular expansion including SDR cards.
Battery is 24000 mWh / 7000 mAh (not final); Wi-Fi 6 via MediaTek MT7921AU with Bluetooth 5.2 integrated.
Hacker News Comment Review
Major concern: no built-in sub-1GHz, NFC, or RFID radio unlike Flipper Zero; the M.2 slot is the intended answer for SDR coverage (e.g., 30 MHz to 11 GHz via third-party modules), but this requires an extra purchase and changes the form factor.
Dual Gigabit Ethernet is the most-discussed hardware win: commenters see inline MITM, VLAN inspection, 802.1X capture, ARP mapping, and WoL tooling as primary use cases that make it genuinely useful for network operators.
The device is viewed as a different product class from Flipper Zero rather than a successor, closer to a pocket Linux pentesting platform with optional radio than a dedicated protocol hacking toy.
Notable Comments
@sterlind: Flags absence of NFC/RFID/sub-1GHz and argues Flipper One should have been an SDR with an FPGA at its core.
@tonyarkles: “This is not an incremental improvement over the Flipper Zero, this is something else entirely.”
