Announced on August 12, 2019, Arduino has partnered with the London-based Chirp, a wireless data-over-sound software solution for machine-to-machine connectivity. The system has the ability to work online or offline, as long as there is a loudspeaker and a microphone available. The software works with the Arduino Nano 33 BLE Sense board in send and receive mode, while most Arduino MKR boards and Arduino Nano 33 IoT will also be supported by the SDK, but only to send data. The software and board are fully compatible with SDKs from a wide variety of platforms. The Nano 33 BLE Sense is available for purchase from the Arduino website, for $29.50. The sensor-rich Arduino Nano 33 BLE Sense is application-ready right out of the box, and Chirp is ready to start sending encoded data from a device fitted with an audio speaker, to the board’s built-in microphone, where it is encoded and […]
Teensy 4.0 Launched for $20 with a Much Faster NXP i.MX RT1062 Arm Cortex-M7 Processor
We last wrote about Teensy boards in 2016 for the launch of Teensy 3.5 & 3.6 boards powered by NXP Kinetis K64/K66 Arm Cortex-M4 microcontroller, and a longer form factor. Paul Stoffregen has now upped the ante with Teensy 4.0 featuring a much more powerful NXP i.MX RT1062 Cortex-M7 cross-over processor clocked at 600 MHz, and going back to the original, and more compact, form factor of earlier Teensy boards such as Teensy 3.2. Teensy 4.0 hardware specifications: SoC – NXP i.MX RT1062 Arm Cortex-M7 processor at 600 MHz with 1024KB RAM (512KB is tightly coupled), Storage – 2048KB serial flash (64KB reserved for recovery & EEPROM emulation) USB – 1x micro USB port for power and programming Expansion via through-holes and pads USB – 2x USB ports, both 480 MBit/sec Storage – 1x SDIO (4 bit) native SD Audio – 2x I2S Digital Audio, 1x S/PDIF Digital Audio Serial […]
MINIX NEO S2 USB-C SSD Hub Review in Ubuntu 18.04 with Khadas Edge
MINIX NEO S1 & S2 are USB-C hubs with the usual HDMI and USB outputs, but also a built-in 120 GB & 240 GB SSD respectively. The company has sent me a sample of each, and in order to test the platform, I decided to do on a Khadas board running Ubuntu 18.04 with LXDE desktop environment (aka Lubuntu). I’ll start by checking out the packages’ content, before going through my experience with the MINIX NEO S2 USB-C hub in Ubuntu 18.04 with LXDE desktop environment. MINIX NEO S1 & S2 Unboxing Both packages are basically identical except for the different color, and one shows 120GB SSD capacity, while the other has 240GB The back side has some more details about the USB-C hub. I’ll focus on the 240GB model since it’s just the same, but around $13 to $20 more expensive, and it offers double the capacity, as well […]
Reading ID Card Data in Ubuntu with EZ100PU Smart Card Reader (Thai ID Edition)
I was asked help with configuring a smart card reader on a government computer running Windows 7, but this made me wonder what would happen if I connected the card reader to my Ubuntu laptop and whether I’d be able to read content from a Thai ID card. EZ100PU Smart Card Reader Let’s have a look at the card reader itself first. It’s a FAST ID EZ100PU smart card reader compliant with ISO7816 standard. That’s the product page of the specific model, but a search for EZ100PU only reveals the manufacturer may be InfoThink Technology based on Taiwan. The USB smart card reader comes with a CD that includes drivers for Windows, Linux, Mac OS, and Android, as well as an SDK with a demo program and sample code in C++, Visual Basic .NET, and C#. As we’ll see further below, the Linux driver is not needed as it works […]
Aviat WTM 4800 5G Multi-band Radio Targets Transport Applications
Aviat Networks has released the WTM 4800, an eBand and Multi-Band Radio focused on 5G transport applications such as autonomous vehicles, remote healthcare, and industrial machine-to-machine communications, while still being able to work with the 4G network. The radio is structured to work with eBand and Multi-Band, all in one unit, and only needing an antenna to function contrary to the usual 2 or 3 radio unit systems. This is the industry’s first and only single box design for a multi-band 5G transport application solution. The unit is said to reduce the total cost of ownership (TCO) significantly. The WTM 4800 does not need an indoor interface for the user as with other solutions, which need to be configured, maintained and installed in a complex series of steps. The WTM is less complicated, easily configured over the cloud and scalable for nearly any type of transportation application needing radio connection. […]
Somu Tiny Open Source FIDO2 Security Key Enables Passwordless Login & Two-factor Authentication (Crowdfunding)
Tomu is a tiny, open source USB connector-sized board powered by a Silicon Labs Happy Gecko Cortex-M0+ MCU that adds two keys to your computer and can work as a Universal 2nd Factor (U2F) token to support two-factor authentication (2FA). But the board is not secure enough for FIDO2 support, and Tomu’s developer worked on a secure USB key called Solokey, and shrank it to Tomu form factor. Meet Somu open-source and secure key with FIDO2 support for compatibility with your Google, Twitter, and GitHub accounts for two-factor authentication, or your Microsoft account passwordless login. Somu hardware specifications: Secure MCU – STMicro STM32L432KC Arm Cortex-M4 microcontroller with TRNG, security isolation for keys, two levels of locked flash Crypto Algorithms – ECC P256 (as per FIDO2 standard) Supported Protocols – FIDO2, U2F Host Interface – USB type-A port Misc – Two touch buttons ( in FIDO2 firmware the two buttons behave […]
MDP-XP is A Modular DC Power Supply Kit For Your Next Project
My love for modular power supply design can not be denied. I find it cool, how you can increase the functionality of relative less powerful device just by adding another device on top or connected to it. With the explosion of the Arduino shields, the Raspberry Pi HaTs, I must say hardware modular design will surely be here for a long time. An interesting modular product discovered on SeeedStudio is the MDP-XP Smart Digital Power Supply Kit. This product is a new product carried by Seeedstudio as it can be seen on the front page, and it is an interesting product indeed. The MDP-XP known as Mini Digital Power System is a system of programmable linear DC power supply inheriting the modular design concept where you can enhance the basic functionality of the device. It is a cost-effective DC power supply, featuring indicators, stability, reliability and distinct user interface comparable […]
Samsung Galaxy Book S Snapdragon 8cx Laptop to Launch soon for $1,000
Qualcomm Snapdragon 8cx was announced as the first Snapdragon processor specifically designed for connected mobile PCs (aka laptops with cellular connectivity) last December. Earlier this year we got confirmation 8cx would support 5G connectivity as an option, and in May, we got news Lenovo Limitless 5G laptop was coming and got some benchmarks showing Snapdragon 8cx with performance similar to an Intel Core i5 Kaby Lake-R processor (15 Watt TDP) while offering much longer battery life. It’s Samsung turn to announce their Snapdragon 8cx laptop with Samsung Galaxy Book S that will be available this fall for $999 and up. Samsung Galaxy Book S specifications: SoC – Qualcomm Snapdragon 8cx Compute Platform with eight 64-bit Armv8 cores in two clusters: Kryo 495 Gold cores (Cortex-A76 class) @ 2.84 GHz + Kryo 495 cores (Cortex-A55 class) @ 1.8GHz ; 7nm process; 7W TDP System Memory – 8GB RAM (LPDDR4X) Storage – […]
