Semtech LoRa SX1272 RF Module Enables Up to 30 KM Wireless Range for Arduino, Raspberry Pi, Waspmote, and More

Libelium’s Waspmote is a board based on Atmel ATmega1281 MCU that interfaces with over 80 sensors, and various wireless communication modules, and targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, smartphone detection, building automation, and so on. They have some professional kits for over 3,000 Euros including training, but a more affordable Starter Kit is also available for 199 Euros on Cooking Hacks. But I’m not going to cover Waspmote in details today. I just mention it because of an article on embedded.com mentioning compatibility with a Libelium / Semtech LoRa SX1272 RF module delivering up to 30km range in ideal conditions (and usually 22+ km range in LOS), and about 2km range in urban settings. I previously featured XBee-PRO 900HP RF Module with a 45km range, so the Semtech module is just another option, and it works not only with Waspmote, but also the […]

$249 Jolla Tablet Runs Sailfish OS 2.0 on a Quad Core Intel Processor (Crowdfunding)

After launching the Jolla phone last year, Jolla has now unveiled the Jolla Tablet running the company’s Sailfish OS, and just like Nokia N1, powered by a quad core Intel processor. Instead of directly using a pre-order system like with the Jolla smartphone, they’ve decided to launch an Indiegogo campaign, and price the tablet much more aggressively than the phone, as perks started at just $189 for early backers. Jolla tablet specifications: SoC – Unnamed Intel 64-bit quad core processor @ 1.8 GHz, which should be Z3740(D), Z3745(D) or Z3560 processor. System Memory – 2GB DDR3L-RS Storage – 32GB eMMC + micro SD slot up to 32GB Display – 7.85″ IPS display, 2048 x 1536 resolution, 5-point capacitive touch Camera – 5.0MP rear camera, 2.0MP front-facing camera Audio – 3.5mm audio jack + speaker(s)? Connectivity – Dual band 802.11 a/b/g/n Wi-Fi, GPS Sensors – Accelerometer, light sensor, and proximity sensor. […]

CubieTruck Metal Case Unboxing and Disassembly

CubieTruck Metal Case is a kit comprised of CubieTruck (aka CubieBoard 3), a 128GB SSD, a 5,300 mAh battery, a power adapter, and various cables. In case you are not familiar with CubieTruck, it’s a development board by CubieTech, based on Allwinner A20 dual core ARM Cortex A7 processor with 2GB RAM, 8GB NAND flash, a SATA connector, HDMI & VGA outputs, Gigabit Ethernet, 2 USB host ports, and a mini USB OTG port. CubieTech decided to sent me a kit, as it was featured on CNX Software, and today, I’ll show what’s exactly is inside the kit since the product description is not 100% clear. I’ve been told it’s pre-installed with Lubuntu, so in a separate post next week, I’ll try Linux, report on the SSD performance, and check the battery UPS function, and possibly life on a charge. CubieTruck Metal Case Unboxing I’ve received the kit in a […]

Nokia N1 is a 7.9″ Quad Core Intel Tablet Running Android 5.0 Lollipop

Since Microsoft bought Nokia’s smartphone division, the company is not allowed to sell smartphones until after the end of 2015, but that does not mean Nokia is standing still, and they’ve just unveiled Nokia N1 tablet based on Intel Atom Z3580 quad core processor, with a 7.9″ display, 2GB LPDDR3, and 32GB eMMC. The tablet runs Android 5.0 Lollipop, and it’s also the first device I’ve seen with a micro USB 2.0 type C reversible connector.

MINIX NEO X6 Media Hub Review

Last week-end, I took a few pictures of MINIX NEO X6 media hub, and had a look at the company’s firmware and forum support which indeed seems to be good. Today, I’ve completed the full review of MINIX NEO X6, and I will compare it to two of its lower priced competitors: MXQ S85 and EM6Q-MXQ. First Boot, Settings and First Impressions The IR remote control works fine, including continuous up ad down pressing, but I switched to using Mele F10 Deluxe air mouse for convenience. I’ve connected an Ethernet cable, an HDMI cable, a micro SD card, a USB hard drive, and a USB hub with two RF dongles for my air mouse and gamepad, a USB flash drive, and a UVC webcam. I’ve connected the power, pressed the power button on the side of the box, but nothing happened at first… You have to press the button one […]
