Allwinner MR133 Processor Targets Robot Vacuum Cleaners

It’s been a while since I’ve seen a new processor from Allwinner, so today I got curious and visited the company website hoping to find maybe some news about the first Cortex-A7x processor from the company. But instead I found something else intriguing with the new Allwinner MR133 processor specifically designed for “SLAM/VSLAM intelligent robot sweeper solutions”. In other words, Allwinner has just launched a processor for robot vacuum cleaners… Allwinner MR133 key features and specifications: CPU – Quad-core Arm Cortex-A7 processor @ 1.8GHz with 32KB L1 I-cache + 32KB L1 D-cache per core, 512KB L2 cache, low-power CoolFlex power management architecture GPU – Arm Mali 400MP2 with support for OpenGL ES 2.0/1.1, Direct3D 11.1, OpenVG 1.1 Memory I/F – 32-bit DDR4/DDR3/DDR3L/LPDDR3/LPDDR4 Storage I/F – eMMC 5.0 flasj, compatible with eMMC 5.1, support Full Disk Encryption(FDE) 8-bit TLC/MLC/SLC/EF NAND flash, supports FDE LDPC/80-bit BCH/1024bytes Video Engine – H264 HP encoder 1080p @ 60fps, JPEG encoder up to 4096 x 4096 …

NiteFury Puts Xilinx Artix-7 FPGA into an M.2 Card (Crowdfunding)

NiteFury is an FPGA development board, but it works differently than most, as RHS Research LLC put a Xilinx Artix-7 FPGA into an M.2 Key M card that you can easily insert into a laptop or mini PC with a 80mm M.2 socket. The board also includes DDR3 memory, and exposes a few configurable I/Os. You can use NiteFury to experiment with Xilinx PCIe IP, but also as FPGA co-processor for example to handle encryption, and encoding/decoding data. NiteFury card specifications: FPGA – Xilinx Artix XC7A200T-2FBG484E delivering up to ~1000 GMAC/s, with 215,360 Logic cells, 33,650 Slices, 269,200 CLB flip-flops, and 740 DSP slices. System Memory – 8 Gbit DDR3 (512 MB x 16) Host Interface – PCIe 4x gen 2 (2 Gb/s) External I/Os Via I/O connectors – 12x I/O including 4x selectable analog or digital – JTAG ready Via PCIe connector – 1x 3.3 V digital I/O (LED), SMBus Misc – 4x LEDs Dimensions – 80 x 22mm; …

ZED Depth and Motion Tracking Camera Supports NVIDIA Jetson Nano Board

When NVIDIA launched their low cost Jetson Nano development board earlier this week, one reader asked whether it would support binocular depth mapping. It turns out Stereo Labs has updated the SDK (Software Development Kit) for the ZED depth and motion tracking camera in order to support the latest NVIDIA developer kit. Jetson Nano can manage depth and positional tracking at 30 fps in PERFORMANCE mode with 720p resolution, and while the more powerful and expensive Jetson TX2 achieves doubles the performance at 60 fps, it does so at a much higher cost. ZED depth and motion tracking camera specifications: Video 2.2K @ 15 fps (4416×1242 resolution) 1080p @ 30 fps (3840×1080 resolution) 720p @ 60 fps (2560×720 resolution) WVGA @ 100 fps (1344×376 resolution) Depth Resolution – Same as selected video resolution Range – 0.5 to 20 m Format – 32-bits Stereo Baseline – 120 mm Motion 6-axis Pose Accuracy Position – +/- 1mm Orientation – 0.1° Frequency – …

Sigfox Targets Worldwide Coverage with Satellite Launch

LPWAN technologies such as NB-IoT, Sigfox, and LoRa deliver low power, long range communication at low bitrate and can be used for asset tracking, environmental monitoring, water & electricity meters, and so on. The line-of-sight range between the closest gateway and nodes is usually 10 to 20 km, and coverage can be expanded by connecting several gateways to form a network. However, this is not workable in all locations worldwide, so Sigfox plans to launch a Sigfox satellite in collaboration with Eutelsat in order to provide coverage in places like large deserts such as the Sahara desert, the two poles, as well as oceans as explained by Franck Siegel, chief operating officer at Sigfox. This will for instance enable tracking and monitoring of oil platforms and vessels. The press release does not explains much except Sigfox and Eutelsat will test the first Satellite in H2 2019 before the commercial launch of the “ELO” constellation in 2020. An article on ConnectedBaltics, …

Alfawise W10 is a $300 Resin (SLA) 3D Printer

Most 3D printers on the market work with filaments using fused deposition modeling (FDM) technology, but in the past we’ve also seen 3D printers using resin and stereolithography apparatus (SLA) technology. The latter is supposed to enable more detailed, yet faster prints, but storing and keeping the liquid resin is a bit more challenging than simply handling filament. In the past I had come across two resin 3D printers in the news, namely the infamous Peachy printer, and the $99 ONO 3D printer working with a smartphone, which was introduced in 2016, but the company is still working on the printer, and most backers have not received their rewards. But today, I’ve come across another resin 3D printer with Alfawise W10 that’s available for $299.99 plus a few dollars for shipping. Alfawise W10 key features & specifications: Display – 2.5″ full color LCD display Storage – microSD card slot Build size – 98 x 55 x 140 mm Layer thickness …

MT3620 Mini Dev Board is a Cheaper Microsoft Azure Sphere Board

Announced nearly one year ago, Microsoft Azure Sphere is an ecosystem comprised of Azure MCUs with Microsoft Pluton Security System, Linux based Azure Sphere OS, and a secure cloud service called Azure Sphere Security Service. The first official Azure development board – MT3620 Development Board for Azure Sphere – was launched last year for $84.95. The kit may not have attracted a large number of developers, so there’s now a cheaper version – MT3620 Mini Dev board – going for $34.90 on Seeed Studio. Note that’s a pre-order and shipping is scheduled for May 13, 2019. MT3620 Mini dev board specifications: CPU Module – AI-Link WF-M620-RSA1 module with Mediatek MT3620AN single core Arm Cortex-A7 processor @ 500 MHz with 4MB SRAM, dual core Arm Cortex-M4F real-time core @ 200 MHz with 64KB RAM, Pluton security sub-system, and WiFi.
