Particle’s M-series multi-radio devices connect anywhere with WiFi, cellular, NTN satellite, and LoRaWAN connectivity

Particle M-series M-SoM versions

Particle Industries Inc., an IoT Platform-as-a-Service company, has announced a new line of multi-radio boards and modules that offer multiple connectivity options in a single product. Particle is a complete edge-to-cloud IoT development platform that offers hardware products and software tools for creating IoT solutions. The company’s latest product, the M-series, has a bold tagline: connect anywhere. Although wireless connectivity has come a long way, there is no single wireless technology that works everywhere. Particle’s M-series aims to address that problem by bundling multiple radios – Wi-Fi, cellular, satellite, and LoRaWAN – into one product. Particle is looking to expand from its two primary wireless technologies: Wi-Fi and cellular, and add two more radios, satellite and LoRaWAN, for broader coverage. These two radios will cover devices in areas such as enclosed spaces (boiler rooms, elevator shafts, basements, and mines) and remote locations (methane sensors in oil and gas plants, boats, […]

Spark Analyzer is an ESP32-C3-powered device built to streamline the process of developing and debugging USB-C Power Delivery (UCPD) solutions. The board’s design is simple, compact, and includes helpful power delivery and analysis functionality, at an affordable price. Spark Analyzer runs on an ESP32-C3FH4 microcontroller, a low-power SoC with a single-core RISC-V CPU with onboard 2.4 GHz Wi-Fi and Bluetooth 5 (Low Energy) connectivity. The wireless chip lets users control the Spark Analyzer and monitor its operation remotely. It also supports integration with other smart devices via Matter.  The device allows you to adjust voltage output from 5V to 20V, depending on your project requirements. Power is sent to a connected device via the two-pin screw terminal block on the device, and a Cross Chip sensor measures the electrical current sent through the device using Hall effect. It includes a software safety feature that turns off the output field-effect […]

Microchip announces the PolarFire SoC Discovery Kit, a low-cost devkit for Linux and real-time applications

Microchip PolarFire SoC Discovery Kit

The SoC Discovery Kit is the latest addition to Microchip’s list of development kits for the PolarFire series. The series is the first SoC FPGA family powered by a deterministic, coherent RISC-V CPU cluster. They provide low power consumption, thermal efficiency, and defense-grade security for smart, networked systems. They also support a deterministic L2 memory system for Linux and real-time applications. Microchip launched the Icicle Kit for the PolarFire SoC in 2020 and it was followed by the Video and Imaging Kit which was intended for mid-bandwidth imaging and video applications. Now, Microchip has announced the Discovery Kit which is billed as a low-cost alternative to the Icicle. The Discovery Kit retains the full range of features needed for testing concepts quickly, developing firmware applications, and programming/debugging user code. According to Microchip, the kit will bring “a low-cost RISC-V and FPGA development for learning and rapid innovation” to new and […]

m1 multitool device

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)

nrfice fpga board

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)

Ovrdrive USB flash

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 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 […]

Boondock Echo front

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 […]
