The M1 device is a Flipper Zero alternative with a faster STM32H5 microcontroller and Wi-Fi connectivity (Crowdfunding)

The M1 is a multitool device that bundles several hacking and penetration tools in a package that looks like a retro-gaming console and could be viewed as a Flipper Zero alternative with a more powerful STMicro STM32H5 Cortex-M33 high-performance MCU featuring Arm TrustZone hardware-based security for additional protection for sensitive data. The M1 multitool device features transceivers for infrared, sub-1 GHz, Bluetooth, NFC, RFID, and Wi-Fi. This means that the M1 can replace most of your remotes as well as your RFID and NFC-based items (membership cards, access fobs, business cards, credit cards, etc.) It also has twelve 3.3V (5V tolerant) GPIO pins that can be used to add extra functionality to the device. M1 specifications: MCU – STM32H5-series microcontroller, with a 32-bit ARM Cortex-M33 core, 1MB RAM Storage – MicroSD card slot Display – 1.54-inch display, 128 x 64 resolution Connectivity Bluetooth 4.2 BR/EDR BLE Sensitivity -96dBm Infrared – […]

NRFICE is a Bluetooth FPGA board in the Arduino UNO form factor (Crowdfunding)

The NRFICE FPGA is a Bluetooth FPGA board designed for edge computing and IoT applications. It is built upon a combination of the dual-core nRF5340 Bluetooth SoC and the Lattice ICE40UP5K FPGA. The ICE40 UltraPlus is a low-power, high-performance FPGA for edge computing and artificial intelligence projects and the nRF5340 is a Bluetooth 5.3 SoC that supports Bluetooth Low Energy (BLE), Bluetooth Mesh, Thread, NFC, and Zigbee. Through the Nordic nRF5340, NRFICE can load a project directly into the iCE40 FPGA, bypassing the usual extensive toolchain setup. This enables a new class of FPGA development, where bitstreams can be hosted in the cloud, selected by a user on their phone, and loaded wirelessly to the board. It features a built-in J-Link OB for easy debugging and programming without the need for emulator dongles and is similar to the previously covered Segger emPower evaluation board in this regard. This board supports […]

Ovrdrive USB is an open-source, privacy-oriented USB flash drive that can self-destruct (Crowdfunding)

We have previously covered the Tillitis Tkey, an open-source security key in a USB-C case but the Ovrdrive USB stick is not a security key. It is a simple, plain USB flash drive with a special security feature. It will appear completely blank unless you plug this drive in three times in quick succession. The Ovrdrive flash drive is aimed at journalists in repressive areas and security researchers but may be useful to other security and open-source hardware enthusiasts. As for how it works, the Ovrdrive has two identical circuits connected to the ATtiny24A microcontroller that controls the rapid plug-in functionality. When the flash is plugged in, the microcontroller powers on, and the CHG1 node goes high, charging C3 through D2. The pin will remain high for a while and then slowly discharge via R1 and body resistance. C3 and the identical C14 will remain high through power cycling/a quick […]

Tangara is a portable, open-source music player based on an ESP32 MCU (Crowdfunding)

Tangara is a portable music player that is out to make MP3 players cool again. With an iPod-inspired design and an ESP32 module at its core, Tangara presents an open-source and nostalgic way to listen to your favorite music and podcasts. The ESP32-WROVER-E at the core of the music player is the main microcontroller but it also features a co-processor, a Microchip SAMD21, which is responsible for USB communication and power management. We have covered the ESP32-WROVER-KIT, a development kit for the ESP32-WROVER and ESP-WROOM-32 line of modules with a JTAG interface and an LCD. The Tangara music player can output audio through a 3.5mm headphone jack or Bluetooth, although Bluetooth is currently limited to the default SBC codec. Tangara is the brainchild of Australian tech company Cool Tech Zone and is aimed at the portable media player community at large. This is reflected in many of the design choices […]

The Boondock Echo is an internet-connected ham radio powered by the ESP32-A1S devkit (Crowdfunding)

The Boondock Echo is an open-source, internet-backed recording and playback device for two-way devices. It can denoise, transcribe, translate, and send emails on hearing keywords/call signs. It is a low-cost solution for timeshift radio communication that enables users to monitor frequencies and record audio from a connected radio. Captured messages are uploaded to a server and transcribed using OpenAI. On the cloud server, the audio messages also pass through some DSP (digital speech processing) algorithms for noise reduction and volume normalization to enhance their clarity and usability. The Boondock Echo is aimed at amateur radio operators and first responders in remote areas and during emergencies, situations where traditional two-way radios tend to be unclear and unreliable. Multiple devices can be linked together to form a ‘dockpack’ and monitor/record multiple frequencies at once. Boondock Echo specifications: Mainboard – ESP32-A1S (ESP32 Audio Kit) running at up to 240MHz Expansion Board – Boondock […]

EVN Alpha is a LEGO-compatible robotics controller built around Raspberry Pi RP2040 MCU (Crowdfunding)

The EVN Alpha is a robotics project from a team based in Singapore and is aimed at roboticists seeking an advanced building platform beyond what LEGO Robotics kits offer. This robotics controller can be considered a spiritual successor to the LEGO MINDSTORMS EV3 intelligent brick. It runs on the Raspberry Pi RP2040 microcontroller with two Cortex M0+ cores running at a maximum clock speed of 133 MHz and 264KB of embedded SRAM and builds upon the rich software support available for the microcontroller. It features 64 LEGO Technic-compatible holes on five sides for easy installation into your projects and has 26 ports for I2C, UART, servos, EV3, and NXT motors. It is smaller volumetrically than the LEGO bricks and can be powered from two generic 18650 Lithium-ion cells rather than a proprietary solution (unlike the LEGO SPIKE Prime). The EVN Alpha was created as a “basecamp for students looking to […]

Renesas releases the DA14592, a new dual-core Cortex-M33/M0+ BLE chip with integrated flash

The DA14592 System-on-Chip (Soc) is Renesas’ “lowest power consumption and smallest, multi-core Bluetooth LE device.” According to the company, this chip’s design was achieved by making careful tradeoffs between on-chip memory and die size. The chip offers an ultra-low power mode that uses only 2.3mA when transmitting radio signals at 0dBm and consumes 1.2mA to receive radio signals. It also supports a hibernation mode that uses about 90nA and can extend the operating life of battery-powered products. The active mode is best for processing-intensive products and uses 34µA for every MHz of CPU clock. Projected key applications for the DA14592 chip include crowd-sourced location (CSL) tracking as used in Apple’s Airtags, remote control units, human interface devices, asset tracking, IoT end nodes, data logging, connected health, and activity tracking. Renesas DA14592 specifications: CPU cores: Cortex-M33F running at up to 64MHz as application core Cortex-M0+ at 64MHz as configurable MAC Memory: […]

Jetway launches the JF35-ADN1– A 3.5” Intel N97 SBC designed for industrial robotics applications

Jetway, an AAEON-affiliated manufacturer, has released a new single-board computer, the JF35-ADN1, targeted at industrial robotics applications. The JF35-ADN1 is a subcompact, 3.5” board that is powered by the Intel N97 (formerly Alder Lake) processor. It features several high-speed interfaces and peripherals for its target applications including two 2.5GbE ports, a total of eight USB 2.0 ports (physical ports and internal connectors), two USB 3.2 Gen 2 ports (Type-A and Type-C), and supports up to 32GB of DDR5 RAM via a SO-DIMM socket. It can power up to three displays via two HDMI 2.0b ports and a DisplayPort over USB-C port. The Jetway JF35-ADN1 SBC is aimed at Automated Guided Vehicles (AGV) applications, but it is stated to be versatile enough to accommodate other uses such as machine vision and payment systems solutions. The JF35-ADN1 features the same Intel N97 processor as AAEON’s Up Xtreme 7100 and is intended for […]
