LIVA Q2 Review – ECS Micro PC Tested with Windows 10 and Ubuntu 18.10

ECS LIVA Q2 Teardown

ECS (Elitegroup Computer Systems) is a Taiwanese company that has been offering mini PCs for several years now. Last year they announced their ‘pocket-sized’ model the LIVA Q. Originally featuring Apollo Lake SoCs it has now been upgraded and renamed as the LIVA Q2 and offers a choice of Gemini Lake SoCs. The distinguishing feature of the LIVA Q series however is the form-factor. Compared with Intel Compute ‘stick’ PCs and Intel NUC ‘mini’ PCs the LIVA Q2 is a ‘micro’ PC. This micro PC is like a minimalist mini PC that includes just the minimum number of useful ports namely a couple of USB ports (3.1 and 2.0) on one side, a micro SD card slot on another and finally an HDMI (2.0) and gigabit Ethernet at the rear. The resultant micro PC is beautifully small consisting of a 70mm (2.76″) square case by 33.4mm (1.31”) tall which can […]

802.15.4z Standard to Provide Real-time Centimeter Accuracy Indoor Positioning

802.15.4z timing method

GNSS (Global Navigation Satellite System) solutions like GPS or Beidou offers outdoor positioning with an accuracy of about 2-in-3 meters in optimal conditions for consumer devices, and starting in 2022, the upcoming GPS III will bring that down to as low as 1 meter again in consumer devices. For that only works for outdoor positioning, and for indoor positioning we’ve already covered WiFi RTT, and Bluetooth proximity beacons. The latter has been around for a while, but does not really provide accurate indoor positioning since they’d usually report the distance with less than 10 meters accuracy, and the lag is fairly large with 3 to 6 seconds needed to estimate the distance. The recently released Bluetooth 5.1 specification addresses this issue by enabling location services accurate to within 10 centimeters thanks to a new direction-finding capability made possible with an antenna array. However, as pointed out by EETAsia, there’s another […]

Spare TV Box Board Sold for MXQ-4Q / MXQPro DIY Repairs

Spare TV Box board

Once somebody asked me if spare TV box boards were available for purchase since his TV box died after a few months, and he wanted to repair it himself without having to purchase another complete TV box. Usually, such boards are not sold, except maybe on Alibaba, where you may or may not have to purchase in quantities. So I basically told him it would be hard to find, and buying a new or second hand TV box would be a better option. But I was recently made aware that at least one seller was offering spare TV box boards for MXQ-4Q and MXQPro on Aliexpress for $20.61 shipped in order to let people repair their boxes themselves. If your goal is to repair a TV box, I can only think of two reasons for buying a spare TV box board: saving money and/or reducing electronics waste. MXQ-4Q and MXQPro […]

GL-USB150 OpenWrt Microrouter Looks Like a USB Flash Drive

GL-USB150 Microrouter

There are plenty of small low cost routers capable of running OpenWrt, including the TP-Link WR703N or Marstek MPR-N9 model which we covered several year ago. GL.inet also made several tiny routers that ended up being supported by OpenWrt, including their GL-USB150 microrouter that looks like a USB flash drive, but is really an Atheros AR9331 router that can be powered by any USB ports. GL-USB150 microrouter specifications: CPU – Qualcomm QCA9331 (Atheros AR9331) MIPS processor @ 400MHz System Memory – 64MB DDRII Storage – 16MB NOR Flash Connectivity – 2.4GHz 802.11b/g/n WiFi up up 150Mbps transmission rate Power input – 5V/1A via USB port Power consumption – <1W Dimension – 82x24x11mm Weight – 10 grams There’s no Ethernet port, no extra USB port to add 3G/4G connectivity, and the microrouter can either be accessed wirelessly when connected to a power bank, or via Ethernet over USB when connected to […]

Qihua CQH6 SoM – A Better Alternative to Raspberry Pi Compute Model 3+?

Allwinner H6 SoM

The Raspberry Pi Foundation just launched the Raspberry Pi Compute Module 3+ for $25 and up with Broadcom BCM2837B0 processor offering better thermals than BCM2837 processor. As is often the case, this post generated some insightful comments from the smart readers of CNX Software, and they pointed out some of the shortcomings of the module such as the lack of Ethernet support that would be required for cluster use cases for example. You can also add a USB to Ethernet chip to the carrier board, but that’s not ideal, and instead someone linked to Qihua CQH6 system-on-module powered by Allwinner H6 processor and sold for 158 RMB ($23.5 USD) or 199 RMB ($29.65) for respectively 512MB RAM/4GB flash and 1GB RAM/8GB flash configurations. Qihua CQH6 module specifications: SoC – Allwinner H6 quad-core Cortex A53 processor @ 1.8 GHz with Arm Mali-T720MP GPU System Memory – 512MB, 1GB or 2GB DDR3L […]

PineBook Pro Linux / BSD Rockchip RK3399 Laptop Coming Up for $200

Pinebook Pro

Pine64 announced the Pinebook laptop in 2016. The ultra cheap ($89 and up) laptop was based on Allwinner A64 quad core Cortex A53 processor coupled with 2GB RAM, 16GB storage, and a 11.6″ or 14″ display. It was never meant to be a replacement for your current laptop due to the low end specifications, but you could still use it to tinker with Arm Linux or *BSD, as a lightweight portable terminal, etc… Pine64 made several announcements in a single blog post right before FOSDEM 2019 where they’ll showcase some of their upcoming products including the Pinephone development kit that’s use to develop software for the upcoming Pinephone open source phone, PineTab *BSD/Linux-only tablet with  Allwinner A64 SoC, and an 11.6″ display like Pinebook laptop, a retro gaming case compatible with Rock64 and Rock64Pro boards, an open source IP camera based on Allwinner S3L processor,  Pine H64 Model B (Allwinner […]

MXCHIP EMW3060 WiFi IoT module sells for less than $2

MXCHIP EMW3060

Over the last few years, we’ve seen several Arm based WiFi IoT modules trying to compete with Tensilica based ESP8266 including Pine64 PADI IoT Stamp and Air602 WiFi IoT modules with similar functionalities and price (around $2) as the Espressif modules. I have not seen many projects with any of those Arm based wireless modules, likely because Espressif Systems software ecosystem is mature, and it’s hard to compete for new entrants. Nevertheless there’s a new Arm WiFi IoT module, not based on Cortex-M core, but instead, MXCHIP EMW3060 is equipped with an older ARM9 core, 256KB RAM, and 2MB flash, and sells for just $1.79 on Seeed Studio in single quantity. The price further drops to $1.55 per unit if you order 50 pieces or more. MXCHIP EMW3060 WiFi IoT module specifications: SoC ARM9 core clocked at 120 MHz System Memory – 256KB SRAM Storage – 2MB flash Connectivity – […]
