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 […]

Snickerdoodle Xilinx Zynq ARM + FPGA Board Starts at $55 (Crowdfunding)

While Xilinx Zynq UltraScale+ ARMv8 + FPGA SoC is still in development, there are already quite a few Xilinx Zynq-7000 boards on the market today. The cheapest I know of is MYirTech Z-Turn board selling for $99, but krtkl (pronounced “critical“), US a based startup, will soon bring an even cheaper Zynq-7010/7020 board with their Snickerdoodle board currently listed on CrowdSupply platform for $55 and up, plus shipping. Snickerdoodle board specifications: SoC Xilinx Zynq-7010 dual core Cortex A9 processor @ 667 MHz + FPGA with 430K gates or Xilinx Zynq-7020 dual core Cortex A9 processor @ 866 MHz + FPGA with 1.3million gates (~430K ASIC gates) System Memory – 512MB or 1GB LPDDR2-800 Storage – micro SD card slot, 16MB boot flash Connectivity via Ti Wilink 8 solution 2.4GHz 802.11 b/g/n WiFi + Bluetooth 4.0 or Dual band 802.11 b/g/n WiFi (2×2 MIMO) + Bluetooth 4.0 USB – 1x micro USB port […]

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 […]

Orange Pi PC Not Booting? You Are Not Alone…

Orange Pi PC development board launched at the end of August, and quickly went viral thanks to low $15 price tag. The company, Shenzhen Xunlong Software,  is fairly small, with just over 10 employees, so when they started getting several thousands customers in a short time, they may have been overwhelmed, and this likely resulted in delays with regards to shipping, and acceptance into Orange Pi forums. Several people have now received their boards, and while many found it to work fine, I’ve been informed several people apparently got a non booting device. People on Youtube and Orange Pi Forums also complained about a booting issue until Ethernet lights up, or Ethernet not working, while other reports Linux is working, but not Android. Unless there was a bad batch during manufacturing, it’s hopefully mostly a firmware issue. The person who reports Ethernet not working, first used the images from Orange […]

Digilent ARTY is a $99 Xilinx Artix-7 FPGA Board with Arduino Headers

Low cost FPGA boards with Arduino headers are nothing new, as we’ve seen before with Arduissimo and Papilio DUO, but both of these boards are based on Spartan 6 FPGA, while the recent Digilent ARTY board is powered by an Artix-7 FPGA. Beside the hardware differences, Spartan 6 FPGAs only support Xilinx ISE Design Suite, while Artix-7 parts are also supported by Vivado Design Suite, which according to Xilinx has a much better workflow and user interface. Digilent ARTY specifications: FPGA – Xilinx XC7A35T-L1CSG324I with 33,280 logic cells, 1,800 Kb block RAM, 90 DSP slices, and 250 I/O pins System memory – 256 MB DDR3L SDRAM Storage – 16 MB of QSPI Flash Connectivity – 10/100M Ethernet Expansion interfaces 4 Digilent compatible Pmod interfaces enabling 32 user I/O pins: 2 Pmods routed as differential pairs, paired to fit dual-wide Pmods Arduino UNO R3 shield / chipKit interface Debugging – USB-UART Interface, […]
