Checking out Hologram’s Developer SIM Card for Worldwide IoT Projects

Hologram is a service that offers 2G/3G/4G cellular connectivity for the Internet of Things via a SIM card that works in over 170  countries, and with pricing starting at $0.40 per month. In order to promote their services, the company offers a free developer SIM card which I ordered when I first wrote about the service last month. I was pleased and surprised they would sent it to Asia for free, and I got the card in a bubble envelop. The back of the card includes a 18 to 22 digit SIM card number and bar code, that we’ll need to use for activation, and a link that redirects to https://hologram.io/docs/. I planned to try the card with Wio GPS tracker board which requires a nano SIM card, and there are convenient cutouts to convert the SIM card to micro SIM or nano SIM card formats. Before using the card […]

Videostrong VS-RD-RK3399 Development Board Review – Part 1: Unboxing, Kit Assembly, SDK and Documentation

Videostrong VS-RD-RK3399 development board is a full-featured development based on Rockchip RK3399 hexa-core processor with up to 4GB RAM, and 32GB eMMC flash, and plenty of I/Os. The company has sent me a sample, and after getting some trouble going through customs with questions like “what is a development board?” and “is it a board for TV boxes or computers?”, I finally got hold of the parcel. Today, I’ll check out the board and its accessories, show how to assemble it, and since the company shared more info about documentation and software, quickly go over what’s available. Videostrong VS-RD-RK3399 Development Kit Unboxing The board was in a bland carton box, which is fine since it’s not a consumer product, with a stick showing I got the 4GB LPDDR3 / 32GB eMMC flash version. There’s also a board using 2GB/16GB configuration. The package includes the board, bottom and top acrylic plates […]

Bqeel MVR9 (NT-N9) TV Box Review – Part 2: Android Nougat Firmware, RKMC, YouTube 4K, and More

Bqeel MVR9 is another TV box powered by Rockchip RK3328, but that model comes with Gigabit Ethernet and 2GB RAM contrary to the cheaper A95X R2 TV box I previously reviewed. If you want to check thsee some pictures read “Bqeel MVR9 TV Box Review – Part 1: Specifications, Unboxing and Teardown“, as in this second part I’ll focus on the firmware, and we’ll see if the claims of better 4K video playback thanks to DDR4, optimized RKMC with HD audio pass-through, YouTube 4K, and DRM support are true. First Boot, Setup, and First Impressions One good thing about Bqeel MVR9 is that it comes four 4 USB port, so I did not need to use a USB hub to connect my two RF dongles for MINIX NEO A2 Lite air mouse and Tronsmart Mars G01 gamepad, a Seagate USB 3.0 hard drive, and a USB keyboard I normally use […]

ECDREAM A9 Apollo Lake HDMI “TV Stick” Review with Windows 10 and Ubuntu 17.04

The ECDREAM A9 is arguably the first Intel Apollo Lake ‘PC stick’ available for purchase. However, in reality it is surprisingly large, and when compared to earlier Intel Atom ‘sticks’ and mini PC ‘boxes’ it lies somewhere in between. Measuring 2.3 inches (58 mm) wide and 0.6 inches (16 mm) thick it feels almost double in size of the original Intel Compute Stick (1.5 in/38 mm by 0.5 in/12 mm) and like nearly half of a mini PC (Beelink’s AP34 is 4.7 in/119 mm by 0.8 / 20 mm). Given that you only get two USB ports, an micro SD card slot and the obligatory HDMI and power port, the large size would be better justified if an Ethernet port had also been included given other smaller ‘sticks’ have shown this is possible. However the reason for its size is due to the oversized fan and heatsink… ​ and that […]

MINIX NEO Z83-4 Pro Windows 10 Pro mini PC Review – Part 1: Specs, Unboxing & Teardown

While I reviewed MINIX NEO Z83-4 mini PC last year, I found out the fanless mini PC based on Intel Atom X5-Z8300 processor performed well, even matching some Atom X7-Z8700 and Braswell systems in some cases, and offered some BIOS features not always found in competitor models, with the only real downside being the 32GB eMMC flash with average performance. Since then, it’s become quite popular becoming the best seller on Amazon US in the mini PC category, outselling devices like ASUS Chromebox and Apple Mac Mini, and the company has now launched a new variant called MINIX NEO Z83-4 Pro with Windows 10 Pro, an upgraded Intel Atom X5-Z8350 processor, and an included VESA mount making it more suitable for enterprise applications such as digital signage, point-of-sales, and thin client. MINIX NEO Z83-4 Pro Specifications Highlights show differences against Z83-4 model: SoC – Intel Atom x5-Z8350 “Cherry Trail” quad […]

Zidoo X7 TV Box Review – Part 1: Unboxing & Teardown

Zidoo X7 is another Rockchip RK3328 based TV box that has the advantage of coming with 2GB RAM, 802.11ac WiFi and Bluetooth 4.1, as well as Zidoo firmware support, compared to its cheaper competitors such as A95X R2 TV box. The company sent me a review sample to check out it. As a side note, it was quite a challenge to get the box, as my country of residence enacted a new law requiring a “broadcasting license” to import TV boxes and HDMI dongles, even if you get just one unit, so the first attempt failed to got through customs, but eventually I managed to get the box through a local reseller. Back to the review… As usual I’ll write a first part showcasing the hardware design today, before testing the firmware, and publishing my results next month. Zidoo X7 Unboxing The package shows some of the key features of […]

Pine64 ROCK64 is the first maker board based on Rockchip RK3328 processor, and is potentially interesting for various applications including network storage thanks to USB 3.0 and Gigabit Ethernet, multimedia applications with 4K HDR video support, as well as other applications requiring I/Os. I’ve already tested Rock64 board with Android 7.1 operating system, so today I’ll report by finding and experience with Ubuntu 16.04.3 with MATE desktop. Selecting and Flashing a Linux Image You’ll find several operating systems in the Wiki, but you’ll also find more cutting edge images in ayufan’s github. But first let me explain some vocabulary used for Pine64 firmware files: Engineering version – Becomes with release build based on the stock build develop by Pine64 and the SoC vendor. It’s supposed to be more stable, but get less updates Community versions (currently managed via ayufan) are more frequently updates, and comes with more recent features. You’ll find […]

Checking Out Dodocool DC30S USB type C Hub with USB 3.0 Ports, Power Delivery, HDMI Output, and Card Reader

I reviewed Vorke Z3 Android mini PC last month, the first mini PC I’ve received with a USB type C port capable of handling video output too. I could see support for dual HDMI displays in the firmware, but at the time I did not have a USB type C hub with HDMI output. But Dodocool sent me their DC30C USB type C hub so I’ve finally been able to give a try.
