Khadas is Working on more RK3399 / RK3399Pro Boards, Projector Development Kit, AR Kit

Shenzhen Wesion had already unveiled their Khadas Edge board that works both as a system-on-module and a standalone SBC thanks to an MXM3 connector on one side, and traditional HDMI and USB ports on the other. The Rockchip RK3399 board will be launched on Indiegogo a little later. But the company is working on a few more boards and development kits all based on Rockchip RK3399 or the upcoming RK3399Pro processor with neural processing unit (NPU) for AI workloads acceleration. First we have Khadas Edge-V, very similar to Khadas Edge but with a 40-pin IO header replacing the MXM3 connector, and following Khadas VIM form factor and ports, so for example we get an Ethernet port as well as an extra USB 3.0 port instead of USB 2.0 on Edge. As mentioned in Khadas Edge announcement, the company is also working on Khadas Captain carrier board with MXM3 socket. So we […]

How to Make a Low Cost DIY SD Card Duplicator

If you have to duplicate many SD cards for example to boot Raspbian on multiple Raspberry Pi board, one option is buy one of those SD card duplicators, but the problem is that they are not really cheap, for example the Systor 1-to-7 cards model sells for $540. Bob Brown, a retired senior lecturer, is now teaching K-12 students how to get started with Raspberry Pi boards, and must prepare bootable SD cards for his class. In order to save time, a duplicator would have been nice, but the price is too high, so instead he went with a DIY solution. You’ll first need some hardware, including a powered USB hub with the number of cards you want to duplicate, and corresponding SD card reader, and a larger micro SD card to hold Raspbian and/or other operating systems (optional, only for Raspberry Pi based duplicator). Mr. Brown made a 10-port […]

STMicro STM32F7x0 & H7x0 Value Line Microcontrollers Deliver Cortex-M7 Performance at Lower Cost

STMicro introduces their first Arm Cortex-M7 microcontrollers in 2014 with STM32F7 series clocked up to 200 MHz. The next year, Atmel – now Microchip – announced SAM S70 & SAM E70 Cortex-M7 MCU families clocked at up to 300 MHz, STMicro up the ante to 400 MHz with their STM32H7 family in 2016, and more recently NXP launched their i.MX RT series “crossover” processor with the Cortex-M7 reaching up to 600 MHz. AFAIK, nobody has tried to push the clock speeds higher, but STMicroelectronics most recently unveiled STM32F7x0 & H7x0 Value Line microcontrollers with the same performance level as their earlier STM32F7 and STM32H7 MCUs, but with a lower price by reducing the amount of internal flash. Three Cortex-M7 value line families have been introduced: STM32F730 entry-level MCU @ 216MHz with 64KB flash, 8KB data / instructions cache, 256KB RAM and 16KB+64KB TCM (Tightly Coupled Memory). The microcontroller also includes […]

Nubia–α Wearable Smartphone is a Smartwatch with a Long Curved Display

We have smartphones, we have smartwatches. and we have… Nubia-α that is something in between, and which the company (Nubia) promotes as a “wearable smartphone”. The device comes with a long curved display, and you’d wear it around your wrist just like a watch with access to fitness apps, and music, but just like in a phone, you could make phone calls and send SMS thanks to 4G connectivity, as well as taking selfies or making video calls with its built-in camera. We don’t have the specifications yet, but the thing is real as it was showcased at IFA 2018, although for the eyes only, i.e. no hands-on or even touching the Nubia-α. Engadget reported about the device, and while the reporter clearly did not like the largish camera on the side, she seems impressed by the brightness and colors coming out of the Flex OLED display. The watch / […]

Creality Ender 3 3D Printer Sells for $169.99 (Promo)

From time to time I come across good deals for 3D printers, and a recent promotion for Creality Ender 3 3D printer appears to be one of them. Creality Ender 3 has gotten some pretty good reviews – see video embedded below – in the sub $200 market, and GearBest is now offering the 3D printer for $169.99 including shipping from their Los Angeles warehouse. That deal is only available to the US however, and if you purchase it from the China warehouse (CN-099) price is $179.99 + shipping. That’s still a pretty good price though, as the official Aliexpress store offers the printer for $208 with Fedex shipping.

Compulab WILD WiFi Router Supports WiFi RTT (802.11mc) Location

When Google released the first Android P preview back in March, one interesting new feature was indoor positioning through 802.11mc WiFi aka. WiFi RTT (Round Trip-Time). That looks promising so I started to look for 802.11mc capable routers, and all I could find were some Intel cards and Marvell chips with WiFi RTT, but not actual products. Since then Android 9 has been formally released, and today I’ve learned that Compulab launched a WiFi RTT capable router that will work with Android 9.0 phones. Meet Compulab WILD. Compulab WILD WiFi RTT router specifications: SoC (from a choice among three) Intel Atom x7-E3950 quad core processor @ 1.6 / 2.0 GHz with 18 EU HD graphics; 12W TDP Intel Atom x5-E3930 dual core processor @ 1.3 / 1.8 GHz with 12 EU HD graphics; 6.5W TDP Intel Celeron J3455 quad core processor @ 1.5 / 2.2 GHz with 12 EU HD […]

MINIX NEO U9-H TV Box Gets Android 7.1 Firmware

MINIX NEO U9-H is generally considered one of the best Android TV boxes if you are after an Android experience, as opposed to a pure Android TV experience. I found the firmware solid and performing on very capable hardware when I reviewed the device in 2017 although there were a few bugs here and there for the version of the firmware I tested. The device is still the main TV box model sold by MINIX, but so far, you had to run the older Android 6.0 OS. The good news is that you can now upgrade your box, if you wish to do so, to a more recent Android 7.1 operating system. There’s no specific changelog for the release, and you can find Android 7.1 for MINIX NEO U9-H on MEGA.An important caveat is that it’s not an OTA update, so you’d have to use USB Burning Tool – also […]
