Several weeks ago, as I noticed the lack of Bluetooth 5 USB dongles, I found MakerSpot CC2640 Bluetooth 5 USB stick based on Texas Instrument CC2640R2F Arm Cortex-M3 WiSoC. It’s not exactly a consumer products, and instead it’s more like a development kit, but it can still be inserted into the USB port of your computer or development board. Today, I found out Nordic Semi also made their own Bluetooth 5 – or is it Bluetooth 5.0 now, I’m really confused at this point – USB dongle for evaluation & development based on nRF52840 WiSoC. It’s not only for Bluetooth 5 though, as the multi-protocol SoC also supports Bluetooth Low Energy, Bluetooth Mesh, Thread, Zigbee, 802.15.4, ANT(+), and 2.4 GHz proprietary solutions. nRF52840 USB dongle (PCA10059) key features: Wireless Connectivity – Bluetooth 5, Bluetooth Low Energy, Thread, Zigbee, 802.15.4, ANT/ANT+, and 2.4GHz USB – USB 2.0 ports Expansion – 15x […]
Xiaomi Mi Pad 4 8″ Tablet Comes with Snapdragon 660 Processor, 4G LTE Connectivity
Android tablets are not as popular as they used to be, and the choice of tablets has come down as a results. However, Xiaomi still keeps on updating their Mi Pad family every year or two years. After NVIDIA based Mi Pad in 2014, Intel based Mi Pad 2 in 2015, and Mediatek powered Mi Pad 3 last year, the Chinese company has now launched Mi Pad 4 with a Qualcomm 660 octa-core processor and an 8″ Full HD display. Xiaomi Mi Pad 4 specifications: SoC – Qualcomm Snapdragon 660 octa-core Kryo 260 processor @ up to 2.2 GHz (1.8 GHz for the low power cluster), Adreno 512 GPU with support for OpenGL ES 3.2, OpenCL 2.0 full,Vulkan, DX12, and Hexagon 680 DSP with Hexagon Vector eXtensions (HVX) System Memory – 3 or 4GB LPDDR4x Storage – 32 or 64 GB eMMC 5.1 flash, micro SD card slot up to […]
Top 10 Best Selling TV Boxes (on GearBest)
I’ve already written articles such as the “Best Android TV boxes in 2018” to help people select a TV box that matches their requirements, but today it will be a little different. GearBest provides a speadsheet with discount and coupons to bloggers and YouTube reviewers (sadly not shareable link here), and this time I noticed they also list the top 10 best sellers in the TV box category. Those may not necessarily the best TV boxes, but at least many other people bought them, and you may get unofficial support via communities such as Freaktab or LibreELEC. Withoutany further delay, here’s the list in no particular order and with prices for reference only as listed in the spreadsheet: Mecool M8S PRO L 4K TV Box (Buy Link) – Amlogic S912, 3GB RAM, 32GB flash, Android 7.1 – $75.99 W95 TV Box (2GB) (Buy Link) – Amlogic S905W, 2GB RAM, 16GB flash, […]
BOSON Kits Feature LEGO Compatible Building Blocks for STEM Education
Last year, DFRobot successfully introduced BOSON Kit “Powerful Building Blocks For LEGO STEM”via Kickstarter, and I’ve just noticed the company is now selling two BOSON Kits on their website: BOSON Science Kit for $149 BOSON Inventor Kit for $249 The kits are plug and pay and do not require coding, nor soldering. The modules come with built-in magnets, or they can be attached with screws, Velcro or to LEGO parts. BOSON modules are based on Intel Curie BLE modules, but those are being phased out, so you may want to inquire DFRobot if long term availability / appropriate stock is a concern. BOSON Science Kit As its name gives away, the kit is a set of exploration tool for aspiring young scientist with the following items: 8 scientific sensors for physics, chemistry and biology: Light sensor Humidity sensor Soil moisture sensor Temperature sensor Waterproof temperature sensor pH sensor (That’s the […]
Qotom Q180P/Q190P Mini PC Comes with Four RS-232 DB9 Connectors
Earlier today, I covered Beelink KT03 “Client Computer”, an Apollo Lake barebone mini PC with two COM ports . But as you must already know, people on the Internet are hard to please, so some readers may have thought “meh, no Thunderbolt”, “lol, Apollo Lake… so old”, “where’s the NVMe socket?”. I won’t be addressing those concerns in this post, and instead I will focus on the “meh, only two COM ports, I need four!” crowd. So I went a little web search, and found another low power compact mini PCs with not two, but four COM ports. Qotom Q180P/Q190P are Cherry Trail mini PCs based on Intel Celeron J1800 / J1900 dual/quad core processor respectively. Qotom Q180P/Q190P specifications: SoC (one of the other) Intel Celeron J1800 dual core processor @ 2.41 GHz (base) / (turbo) 2.58 GHz with Intel HD graphics; 10W TDP Intel Celeron J1900 Quad core processor […]
Beelink KT03 Client Computer is a $150 Barebone Mini PC with Two COM Ports
Beelink launched several Apollo Lake mini PCs in the last few years, and despite moving to Intel Gemini Lake family for some of their more recent models such as Beelink S2 or Beelink X45, the company has just launched a new Apollo Lake model. The new Beelink KT03 “client computer” is powered by an Intel Celeron J3455 processor, but differs from other mini PCs from the company, as it is sold barebone without RAM nor storage (nor OS), comes with two DB9 RS-232 connectors, and dual Gigabit Ethernet ports. Beelink KT03 specifications: SoC – Intel Celeron J3455 quad core Apollo Lake processor @ 1.5 GHz / 2.3 GHz (Turbo) with 12 EU Intel HD graphics 500 @ 250/750 MHz; 6W TDP System Memory – 1x SODIMM DDR3L socket, no EEC, 1333/1600/1867 MHz; supports up to 8GB RAM Storage – 64Mbit SPI flash for UEFI/BIOS; support for internal 2.5″ SATA drives, […]
Firefly Team Mailbag – Rockchip Development Boards and Accessories
T-Chip Intelligent Technology Co. is a hardware and software technology services company, and a few years ago they setup the “Firefly Team” to provide development boards running Android and/or Linux distributions to the maker community. If I remember correctly the company started with Firefly-RK3288 development board powered, as its name implies, by Rockchip RK3288 processor. Since then they’ve launched several other Rockchip development boards and modules, which I’ve covered on this blog. The company decided to send me some of their recent boards and accessories, so let’s have a look at what I received in my “mailbag”. I’ve also taken a few photos for those who did not watch the video or prefer close up photos. ROC-RK3328-CC “Renegade” Development Board The first board is ROC-RK3328-CC “Renegade” board which was first launched via a crowdfunding campaign by Libre Computer. Both companies have been collaborating on some boards, and Libre Computer makes […]
