HackBat – DIY open-source hardware Flipper Zero alternative features Raspberry Pi RP2040 MCU, ESP8266 WiFi module, RF transceiver…

HackBat DIY open source pentesting device

HackBat is an open-source hardware pen-testing device designed for hackers and makers and equipped with a Raspberry Pi RP2040 microcontroller, an ESP8266 WiFi module, a sub-GHz RF transceiver, NFC, an OLED display, and more… It’s basically a DIY alternative to the popular Flipper Zero wireless hacking tool, that you can produce and assemble yourself. The Flipper Zero was the victim of its own success with the Canadian government (wrongly) claiming it could easily be used for car theft and planning to ban it (status still unclear right now), so Flipper Zero alternatives such as the M1 multitool device got some traction as backup solutions with some extra features. But any closed-source device could eventually be banned, something that’s close to impossible for an open-source hardware device like the HackBat although policymakers could still decide to impose heavy fines if they wanted to make this type of device illegal… HackBat key […]

NXP i.MX 95 SMARC 2.1 system-on-modules – ADLINK LEC-IMX95 and iWave iW-RainboW-G61M

Several companies have unveiled SMARC 2.1 compliant system-on-modules powered by the NXP i.MX 95 AI SoC, and today we’ll look at the ADLINK LEC-IMX95 and iWave Systems iW-RainboW-G61M and related development/evaluation kits. The NXP i.MX 95 SoC was first unveiled at CES 2023 with up to six Cortex-A55 application cores, a Cortex-M33 real-time core, and a low-power Cortex-M7 core, as well as an eIQ Neutron NPU for machine learning applications. Since then a few companies have unveiled evaluation kits and system-on-modules such as the Toradex Titan evaluation kit or the Variscite DART-MX95 SoM, but none of those were compliant with a SoM standard, but at least two SMARC 2.1 system-on-modules equipped with the NXP i.MX 95 processor have been introduced. ADLINK LEC-IMX95 Specifications: SoC – NXP i.MX 95 CPU Up to 6x Arm Cortex-A55 application cores clocked at 2.0 GHz with 32K I-cache and D-cache, 64KB L2 cache, and 512KB […]

Blaustahl USB storage device features 8KB FRAM with up to 200 years of data retention

Machdyne’s Blaustahl is a USB storage device equipped with a Raspberry Pi RP2040 MCU and 8KB of FRAM with a potential lifespan of over 200 years and designed for long-term storage of text up to about 8,000 characters. FRAM (Ferroelectric RAM) has been around for years delivering ultra-low power consumption, faster writes, and ultra-long write endurance (one million billion read/write cycles) compared to EEPROM or NOR flash, but the cost is quite higher and it’s mostly used in applications that require ultra-low power consumption and non-volatile storage write capabilities such as data logging, sensor networks, batteryless applications. The Blaustahl storage device and USB text editor is one of those. Blaustahl speciications: Microcontroller – Raspberry Pi RP2040 dual-core Cortex-M0 processor at 133MHz and 264kB RAM. Storage 4MB (32Mbit) NOR flash for firmware 8KB (64Kbit) FRAM (Fujitsu MB85RS64) Lifespan – 95 years @ +55°C, over 200 years @ +35°C Endurance – 10^12 […]

ardEEG shield works with Arduino UNO R4 WiFi for biosignals measurement

PiEEG has launched the ardEEG shield specially designed for the Arduino UNO R4 WiFi and capable of measuring biosignals such as those used in electroencephalography (EEG), electromyography (EMG), and electrocardiography (ECG). PiEEG, led by Ildar Rakhmatulin, Research Associate at Heriot-Watt University in Edinburgh, launched the PiEEG shield for Raspberry Pi to enable brain-computer interfaces last year, and now the company has been working on the equivalent design for Arduino with the ardEEG shield equipped with eight channel taking input from wet or dry electrodes. ardEEG shield key features and specifications ADC – Texas Instruments ADS1299 Analog-to-Digital Converter for biopotential measurements Supported board – Arduino UNO R4 WiFi 8 channels for connecting wet or dry electrodes (Electrodes are positioned according to the International 10-20 system) Host interface – Arduino headers with SPI used for data transfer with a frequency from 250 SPS to 16 kSPS and a resolution of 24 bits […]

Arduino Alvik is a 3-wheel robot designed for STEAM education

Arduino Education’s Arduino Alvik is a 3-wheel educational robot that was initially unveiled at the Bett 2024 show in London and designed to teach robotics, programming, and other STEAM subjects. The robot is based on an Arduino Nano ESP32 board and comes with a set of nineteen lessons designed by Arduino Education’s team in collaboration with teachers so that students can learn the basics of IoT, get started with MicroPython, and get themselves familiar with various physics and engineering concepts. The company has yet to provide the full specifications for the Alvik robot, but here’s what we know at this stage: Mainboard – Arduino Nano ESP32 2x wheels plus 1x ball wheel Sensors – “High-quality sensors” that include a ToF ranging sensor, line-following sensors, a 6-axis accelerometer & gyroscope, a proximity sensor, and color sensors.

Official Raspberry Pi M.2 HAT+ launched for $12

The official Raspberry Pi M.2 HAT+ is finally out for $12. The add-on board allows users to connect M.2 M-key peripherals, mainly NVMe SSDs, but also AI accelerators, to their Raspberry Pi 5 leveraging the PCIe connector on the(relatively) new SBC. We have to stress “official” because it’s been possible to do the exact same thing with third-party boards from PineBerry (now PineBoards), Waveshare, Pimoroni, and Geekworm for about half a year. I also had the opportunity to review the GEEKWORM X1001 and Waveshare M.2 PCIe HAT+ with Cytron MAKERDISK SSDs last month. But let’s have a look at what the official Raspberry Pi M.2 HAT+ has to offer. Raspberry Pi M.2 HAT+ M Key specifications: M.2 M-key socket for 2230 or 2242 modules Single-lane PCIe 2.0 interface (500 MB/s peak transfer rate) routed via Raspberry Pi PCIe FFC connector. (Note: PCIe 3.0 should also work fine on most Raspberry […]
