Rabbit-Labs Flipper Zero ESP32-C5 multi-board features CC1101, GPS, and dual-band Wi-Fi 6

Designed by Rabbit-Labs EU, the Flipper Zero ESP32-C5 multi-board is an expansion board for the Flipper Zero built around the ESP32-C5 dual-band Wi-Fi 6 (2.4 GHz and 5 GHz) microcontroller. The board also features a TI CC1101 sub-GHz transceiver, a GPS module, an SD card slot, and a USB-C port for power and programming. Last month, we wrote about the ESP32 Marauder 5G Apex 5 module, another ESP32-C5-based add-on for the Flipper Zero that comes with dual-band Wi-Fi 6, two sub-GHz radios, an NRF24 radio, and a built-in GPS module, which makes it quite bulky, to say the least. Compared to that, Rabbit Labs’ multi-board can be considered a stripped-down, simpler alternative, with a more compact design and straightforward setup. ESP32-C5 multi-board specifications: Main module – ESP32-C5-WROOM-1U SoC – Espressif Systems ESP32-C5 CPU Single-core 32-bit RISC-V processor @ up to 240 MHz Low-power RISC-V core @ 40 MHz acting as the […]

ESP32 Marauder 5G – Apex 5 module for Flipper Zero combines ESP32-C5, two Sub-GHz radios, nRF24, and GPS

Designed by HoneyHoneyTrading, the ESP32 Marauder 5G – Apex 5 Module is an ESP32-C5-based hacking and penetration testing tool for the Flipper Zero, with dual-band WiFi 6 (2.4GHz and 5GHz), two Sub-GHz radios (868MHz and 433MHz), an NRF24 radio, and a built-in GPS. This new Flipper Zero module can be considered an upgrade from the ESP32 Marauder – Double Barrel 5G, as it does not rely on a dual-chip configuration for 5 GHz operation, leveraging the ESP32-C5 dual-band capabilities instead. A microSD card slot handles storage, and the device can also save data directly to the Flipper Zero’s microSD card. It also features five antennas, including WiFi, Sub-GHz, nRF24, and GPS, along with dedicated LED indicators for the Sub-GHz radios and nRF24 activity. There is also a hardware button to toggle 433 MHz and 868 MHz Sub-GHz operation, a USB-C port, and a side button for power management and firmware […]

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. Flipper Zero UV Meter specifications: Target platform – Flipper Zero Sensor module – Sparkfun AS7331 Spectral […]

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 […]
