Flipper Zero hacking tool gets MicroPython support

MicroPython on Flipper Zero

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 […]

$49 Rejeee multiple external temperature sensor for LoRaWAN ships with three DS18B20 temperature sensors

Rejeee multiple external temperature sensor for LoRaWAN

The “Rejeee multiple external temperature sensor for LoRaWAN” is a LoRaWAN solution for temperature sensing that includes three waterproof DS18B20 temperature sensors that could be useful for cold storage, kitchen, and greenhouse monitoring. The device has a waterproof design that can withstand moisture and wet environments, is equipped with sensors measuring temperature within the -40°C to 125°C range, plus low-power LoRaWAN connectivity and Lithium AA batteries that can last up to five years when sending data every 10 minutes. Rejeee multiple external temperature sensor for LoRaWAN specifications: Microcontroller – Unnamed Arm Cortex-M MCU; potentially STMicro STM32L151 Cortex M3 @ 32 MHz based on another temperature sensor from Rejeee. LoRaWAN Data Rate – 300 bps ~ 62.5 kbps Transmit Power – 22 dBm Max. Receiver Sensitivity – -140 dBm (BW = 125 kHz, SF12) Operating Frequency – LF: 433 ~ 510 MHz; HF: 863 ~ 928 MHz Bands EU868, IN865, RU864 […]

Flipper Zero hacking tool gets CAN bus add-on board for vehicle diagnostics and security research

Flipper Zero Add On CANBus

Electronic Cats’ Flipper Add-On CANBus is a new add-on board for the Flipper Zero adding CAN bus communication to the popular wireless hacking tool. Built around the MCP2515 CAN controller chip this add-on card communicates with the Flipper Zero through an SPI interface. It allows users to sniff, send, and log CAN bus packets directly from the Flipper Zero, which means now you can analyze and manipulate CAN bus traffic for vehicle diagnostics, security research, and DIY projects. Previously we have seen Flipper Zero add an RP2040-powered video game module, and before that, we noted the developers launched their own app store with open-source apps. Additionally, we have written about Flipper Zero alternatives such as the M1 multitool so feel free to check those to know more about those solutions.

Arduino to switch from Arm Mbed to Zephyr RTOS

Arduino Zephyr RTOS

Following Arm’s decision to stop supporting Mbed from July 2026 onwards, Arduino has now decided to use Zephyr RTOS instead of Arm Mbed for Arduino boards that rely on the latter including Arduino GIGA, Arduino Nano 33 BLE, Arduino Nano RP2040 Connect, as well as Arduino PRO boards/solutions such as the Portenta, Nicla, and Opta families. Note that Arduino UNO, MKR, and Nano families are not impacted by the change since their Arduino Core implementation does not rely on Mbed. The change is not going to happen overnight as software development takes time, and Arduino plans to release the first beta based on ZephyrOS by the end of 2024. and a rollout for various boards starting in 2025 long before Arm Mbed is phased out for good. Arduino is not new to the Zephyr project as the company became a Silver member last year, and they were aware that Arm […]

NDAA-compliant NVIDIA Jetson Orin NX and Nano bundles target drones

ARK Jetson Orin Nano NDAA Bundle

ARK Electronics has recently introduced NDAA-complaint NVIDIA Jetson Orin NX and Nano bundles designed for drones with the company’s Jetson PAB (Pixhawk Autopilot Bus) carrier board, an ARKV6X flight controller, and an SSD preloaded with NVIDIA Jetpack and the ARK UI. I’ve come across the board following a post on X pointing to an article on Tom’s Hardware about the US passing a bill called “Countering CCP Drones Act” that would effectively ban DJI drones in the US.  DJI is supposed to have a 90% market share of the U.S. hobby market, a 70% market share of the industrial market, and an over 80% market share of the first responder market, so not everybody will be happy if the bill passes in the senate and becomes enacted by the US president. But US companies making NDAA-compliant hardware and drones may bit mind, and that’s how I discovered ARK Electronics NVIDIA […]
