Weightless Development Kits are Finally Available (Sort of)

The first version of the Weightless standard aiming at lowering cost of IoT communications was published in 2013, but so far development kits were nowhere to be found. Nwave has now launched a Weightless-N SDK using sub-GHz spectrum, but not the white space spectrum used by Weightless-W, probably due to regulatory hurdles. Specifications and features of Nwave development board: MCU – Silicon Labs EFM32G210F128 ARM Cortex M3 MCU @ 32 MHz with 128KB flash, 16KB SRAM Connectivity – RM3 radio module (868MHz) and antenna connector (X3) USB – X1 USB port for connection to PC or UART interface, X2 micro USB port Debugging – UART, and 10-pin JTAG connector (X4) Expansion header – 16 through holes for GND, 3.3V, GPIOs, ADC, Timers output, I2C, etc… (X5) Misc – Three Jumpers for UART and other selections (TBD), reset buttons for USB ports? Power – 5V via USB ? Dimensions – N/A […]

Marvell EZ-Connect MW302 IoT Starter Kit Supports AWS IoT Cloud Services

Amazon has just launched AWS (Amazon Web Services) IoT (Beta), a cloud platform that lets connected devices securely interact with cloud applications and other IoT devices. As pasrt of the announcement, they also released AWS IoT SDK that comes in three flavors: Embedded C SDK for C-based platforms such as Linux, RTOS, with variants for OpenSSL and mbed TLS. JavaScript SDK in Node.js Arduino Yún SDK. Ten started kits are currently officially supported by AWT IoT, many of them being existing platforms such as LinkIt One, BeagleBone Green, Intel Edison, or TI LaunchPad CC3200, with several of these kits including SeeedStudio’s Grove modules. One of the kits that’s completely new, at least to me, is Marvell EZ-Connect MW302 IoT Starter Kit which include a mini USB to USB cable, and Marvell 88MW302 development board with the following (preliminary) specifications: SoC – Marvell EZ-Connect MW302 ARM Cortex-M4 WiSoC with 512KB SRAM […]

Walabot MIMO Radar Board Can See Through Walls Thanks to Vayyar 3D Imaging Sensors

A few days ago, I wrote about Orbbec Astra 3D camera that can analyze distance and depth to form a 3D image of object. However, this solution uses an IR sensors, and while it can fulfill the needs of many application it does not allow to see through object, and that’s exactly what Walabot wideband MIMO radar board promises to do thanks to Vayyar 3D imaging sensor and a dozen of RF antennas. Some of the key features and preliminary specifications of Walabot board include: Vayyar VYYR2401 3D imaging sensor 12 (or is it 14?) non-contact antennas array system based on “Octopus A3 System on chip” Build in Tx/Rx linear polarized wide-band antennas from 3-10Ghz. On-board Cypress FX3 controller for communication and pre-processing EEPROM (for inventory and calibration information) Walabot interface connectors: Micro-USB 2.0 for high-rate data communication. Option to provide supply from USB. Single supply voltage 4.5-5.5v input for […]

Roseapple Pi Board Powered by Actions Semi S500 Comes with 2GB RAM

[Update: I’ve finally received an answer: Lemon Pi and RoseapplePi makers are different companies, but they just happen to both use the same Actions Semi S500 reference design, and RoseapplePi is manufactured in Taiwan. The picture above is V1.0 board, but V1.1 will have some modifications] Lemon Pi development board was launched this May via a Indiegogo campaign. The board, based Actions Semi S500 quad core Cortex A9 processor, got fully funded by over 200 backers, but at the time of launch, some people questioned the used of the word “Lemon” in a product name, as it has several pejorative meanings, including “something that is useless or crappy”. I was contacted about a new Roseapple Pi board yesterday, and upon checking out the details, it looks exactly like the Lemon Pi, except it got upgraded to 2GB RAM, just like in Indiegogo… The board name on the PCB also reads […]

AMS AS7000 Biosensor is Designed for Strapless Optical Heart Rate Monitors

Heart rate monitors (HRM) with chest straps are now being replaced by more comfortable strapless HRM, such as UWatch UX. These products are enabled by photoelectric sensors that sample light modulated by blood vessels, which expand and contract as blood pulses through them. One of such solutions is the recently introduced AMS AS7000 including a Cortex M0 core, and a DSP implementing algorithm to process raw photoplethysmography (PPG) readings from the sensors to convert them into digital HRM and HRV (Heart Rate Variability) values. Highlights of AS7000 Biosensor: MCU – ARM Cortex M0 with 4KB RAM, 32 KB EEPROM I/Os – 9 GPIOs, UART, SPI, I2C Analog electrical and optical Frontends Hardware sequencer Synchronous detector Integrated LEd driver with current control Optical filters Supply Voltage – 2.6 – 3.6V Temperature Range –30 to 70°C Package – 18 pins AS7000 can deliver greater accuracy when it is paired with an external […]

LeMaker Hikey 96Boards Development Board Comes with 1 to 2GB RAM, Sells for $75 and Up

Hikey was the first 64-bit ARM development board compliant with 96Boards specifications, and supported by Linaro. Availability always seemed to be an issue however, and pricing was set to $129. But Lemaker, the makers of Banana Pi boards, recently joined Linaro, and they’ve built a lower cost version of the Hikey board, still featuring Hisilicon Kirin 620 octa-core ARM Cortex-A53 processor, but with 1GB and 2GB RAM versions, priced respectively at $75 and $99.
