Flipper Zero UV Meter

UV Meter for Flipper Zero measures ultraviolet radiation with AS7331 sensor

The UV Meter is a Flipper Zero application designed to measure ultraviolet (UV) radiation using the AS7331 spectral sensor, which can detect UV-A, UV-B, and UV-C wavelengths. Designed for personal and environmental UV monitoring, this tool measures UV exposure levels in everyday scenarios, whether it’s behind windows, under cloud cover, or while wearing sunglasses. It provides real-time irradiance readings in µW/cm², W/m², or mW/m², and calculates safe maximum daily exposure durations based on 2024 TLVs and BEIs from ACGIH, with adjustable factors like eye protection status, gain, and exposure time. A visual meter and warning symbols notify the user of under- or overexposure. The app also displays each UV type’s relative contribution to overall exposure risk. A compact adapter PCB enables easy connection between the Flipper Zero and the AS7331 breakout board via I²C.

The FlippenHeimer is a compact Geiger counter add-on module designed to work with the Flipper Zero. It allows users to monitor beta and gamma radiation levels using the Flipper’s display and power source, making it a portable device to detect radiation. Built around a J305 Geiger–Müller tube, the FlippenHeimer provides real-time data logging, visual feedback via graphs. Other than that, it features “atomic dice roller” functionality that uses the random nature of radioactive decay to generate unpredictable outcomes. Key components of this device include 555 timers, LM358 op-amps, 2N3904 and MPSA42 transistors, inductors, and high-voltage capacitors. These features make this device useful for applications such as environmental awareness, hobbyist radiation monitoring, and generating random values. FlippenHeimer Specifications: Main interface – Connects to Flipper Zero via GPIO/UART (plug-and-play with GPIO header) Detection device – J305 Geiger-Müller glass tube,  suitable for gamma and beta radiation Radiation detection: Detects beta and gamma radiation […]

ESP32 GPS CC1101 3-in-1 expansion Flipper Zero

FlipMods Combo is a 3-in-1 Flipper Zero expansion module with ESP32, GPS, and CC1101 modules

Sacred Labs’ FlipMods Combo is a 3-in-1 expansion module for the Flipper Zero that combines an ESP32 WiFi and Bluetooth SoC, Texas Instruments CC1101 Sub-GHz wireless microcontroller, and an unnamed GPS module. The expansion module is housed in a neat 3D-printed case and features a built-in GPS antenna, external WiFI/Bluetooth & Sub-Ghz antennas, as well as a switch to send the GPS data to the ESP32 chip or the Flipper Zero.

CapibaraZero ESP32-S3 Flipper Zero alternative

CapibaraZero firmware enables low-cost Flipper Zero alternatives based on ESP32-S3 hardware

CapibaraZero open-source firmware aims to offer a low-cost alternative to Flipper Zero for ESP32-S3-based hardware platforms and soon other gizmos with ESP32 wireless microcontrollers, notably the LilyGO T-Embed CC1101, similar to the original T-Embed with ESP32-S3 WiSoC, but also featuring a Texas Instruments CC1101 Sub-GHz microcontroller and an NXP PN532 NFC/RFID module. The Flipper Zero is a popular portable multi-tool for pentesters and hardware hackers based on STMicro STM32WB55 Bluetooth 5 LE & 802.15.4 wireless microcontroller and a TI CC1101 Sub-Ghz MCU that got involved in controversies such as a ban proposal in Canada last year due to its (dubious) potential use for car theft. Since then we’ve seen several alternatives such as Monstatek M1 (that’s yet to be delivered to backers…) and HackBat open-source hardware with Raspberry Pi RP2040,  ESP8266 WiFi module, and the CC1101 RF transceiver. The CapibaraZero firmware offers another way to create your own cheap Flipper […]

MicroPython on Flipper Zero

Flipper Zero hacking tool gets MicroPython support

Developer and engineer Oliver Fabel has developed a port that is designed to run MicroPython on the Flipper Zero. This port allows users to write programs for Flipper Zero in Python, instead of built-in JavaScript. Till now you can access GPIO, ADC, PWM, the speaker, buttons, the display, and infrared communication with this but it doesn’t have support for NFC or RFID yet, and it’s still under development. Previously we have written about various addon boards for the Flipper Zero like the Mayhem v2, the ESP8266 Deauther board, the CAN bus addon board, and other powerful alternatives of the Flipper like The M1 and the HackBat. Feel free to check those out if you are interested in the topic. The process is simple, and you don’t have to do a firmware update to work with MicroPython, you can download the application from the community-driven Flipper app store and are good […]
