Khadas Edge RK3399/RK3399Pro Board Crowdfunding Campaign Launched

Khadas Edge is another upcoming Rockchip RK3399 board that we initially covered this summer, and comes with a particular design in the sense it is both a single board computer with USB and Ethernet port, and a system-on-module through its edge connector. Later on we found out, the company was working on a variant called Khadas Edge-V with the edge connector being replaced by a more standard 40-pin header, as well as Khadas Edge1S powered by Rockchip RK3399Pro for AI applications. The company has now launched the three boards and accessories through an Indiegogo crowdfunding campaign. I’ve already covered the two RK3399 boards in previous post, and  the RK3399Pro based Khadas Edge-1S (2GB RAM, 2x MIPI-CSI, …) will be similar to Edge board but with , so instead I’ll have a closer look at the specifications for Khadas Captain carrier board for Khadas Edge / Edge-1S: Edge connector – 314-pin MXM3 connector for Khadas Edge / Edge-1S Storage – M.2 …

A Closer Look at NVIDIA Jetson Xavier Developer Kit (Video)

NVIDIA Jetson Xavier Developer Kit

NVIDIA unveiled Jetson Xavier module and devkit last month, but the company did not release the full information, and for example we did not get any clear photo of the module and kit. Charbax did shot a video with more details at the time, but NVIDIA has now published more information about their upcoming $1,299 Jetson Xavier Developer Kit, including an introduction video which I’ll  embed at the end of this article. The first thing to understand is that the module is not actually used in the developer kit, and will only used in actual mass-produced products. The main  difference is the thermal solition. The development kit including a large heatsink, while the production module has a thermally conductive plate to let product designer select the most suitable thermal solution for their products. The specifications are still basically the same. For Jetson Xavier (production) module: SoC – NVIDIA Jetson Xavier with 8x 64-bit Armv8.2 processor with 8MB L2 cache and …

Sony SPRESENSE Arduino Compatible GNSS + Audio IoT Board To Sell for $50 (in Japan)

Sony-Spresense-Arduino-Board

Last year,  we covered Sony Spritzer, an Arduino compatible with a Sony hexa-core Arm Cortex-M4F micro-controller, a built-in GNSS receiver, and an audio codec. The product page for this product is now gone, but it appears Sony only renamed it to SPRESENSE, made some design modifications, and is ready to launch the main board for 5,500 JPY (~$50), and the extension board for an extra 3,500 JPY ($32) on July 31, 2018. Sony SPRESENSE main board (CXD5602PWBMAIN1) specifications: MCU – Sony CXD5602 ARM Cortex-M4F ×6 micro-controller clocked at up to 156 MHz with 1.5MB SRAM Storage – 8MB Flash Memory GNSS – GPS & GLONASS Audio – 3.5mm audio jack Expansion I/Os Digital I/O Pins – GPIO, SPI, I2C, UART, PWM, I2S Analog Pins – 2ch (0.7V range) Camera interface USB – 1x micro USB port for programming and power Power Supply – 5V via micro USB port Dimensions – 50 x 20.6 mm Sony SPRESENSE expansion board (CXD5602PWBEXT1) specifications: …

A Day at Chiang Mai Maker Party 4.0

The Chiang Mai Maker Party 4.0 is now taking place until December 9, and I went there today, as I was especially interested in the scheduled NB-IoT talk and workshop to find out what was the status about LPWA in Thailand. But there are many other activities planned, and if you happen to be in Chiang Main in the next few days, you may want to check out the schedule on the event page or Facebook. I’m going to go though what I’ve done today to give you a better idea about the event, or even the maker movement in Thailand. Booth and activity area should be the same over the 4 days, but the talks, open activity, and workshop will be different each day. Today, people could learn how to solder in the activity area. The even was not really big with manufacturers/sellers like ThaiEasyElec, INEX, or Gravitech closer to the entrance… … and slighter higher up in a …

Cheap Evil Tech – WiFi Deauther V2.0 Board and Autonomous Mini Killer Drones

Most technological advances usually improve life of people, and with the costs coming down dramatically over the years, available to more people. But technology can be used for bad, for example by governments and some hackers. Today, I’ve come across two cheap hardware devices that could be considered evil. The first one is actually pretty harmless and can be use for education, but disconnects you from your WiFi, which may bring severe physiological trauma to some people, but should not be life threatening, while the other is downright scary with cheap targeted killing machines. WiFi Deauther V2.0 board Specifications for this naughty little board: Wireless Module based on ESP8266 WiSoC USB – 1x Micro USB type changed, more stable. Expansion – 17-pin header with 1x ADC, 10x GPIOs, power pins Misc – 1x power switch,  battery status LEDs Power Supply 5 to 12V via micro USB port Support for 18650 battery with charging circuit (Over-charge protection, over-discharge protection) Dimensions – …

UFS 3.0 Embedded Flash to Support Full-Duplex 2.4GB/s Transfer Speeds

All my devices still rely on eMMC flash for storage, but premium smartphones, for example, make use of UFS 2.0/UFS 2.1 flash storage with performance similar to SSD, with Samsung UFS 2.0 storage achieving up to 850MB/s read speed, 260 MB/s write speed, and 50K/30K R/W IOPS. UFS 3.0 promises to roughly double the performance of UFS 2.0/2.1 with transfer rates of up to 2.4 GB/s, and separately, the UFS Card v2.0 standard should deliver UFS 2.1 performance on removable storage. Several Chinese and Taiwanese websites, including CTimes and Benchlife, have reported that companies have started getting UFS 3.0 & UFS Card v2.0 licenses from JEDEC, and Phison is working on a controller to support both new standards, and scheduled to launch in 2018. Premium smartphone SoC are only expect to support UFS 3.0 in 2019 and beyond, and hopefully by that time eMMC will have been replaced by UFS 2.0/2.1 in entry level and mid range devices. The outlook for …
