More details about the changes can be found on Xenial Xerus release notes. I’ve also noticed the system […]

Mini Review of NextDrive Plug for Private Cloud Storage and Home Security

NextDrive Plug is an ARM based plug computer that’s used to store your photos or music, and/or as a security system using a webcam combined with Pixi motion sensor. They had a successful crowdfunding campaign, and now that they’ve sent rewards to backers, I’ve also received NextDrive Plug and Pixi for evaluation. The courier was not particularly gentle with the packages, but the devices themselves were not damaged. NextDrive Plus package included the box, a US plug, and a user’s manual in English. Pixi comes with two 3M stickers, and a user’s manual. There’s also a plastic film to avoid depleting the battery, that you’ll need to remove before using the sensor. The interfaces on the plug are minimal with a USB port for a USB mass storage device (HDD, flash drive…) and/or a UVC webcam, and the socket for the power plug adapter on the back.You can then plug […]

SmartEverything is a Feature-Packed IoT Board with SigFox, Bluetooth LE, NFC and GPS Connectivity, Plenty of Sensors

Atmel MCU Madness is an informal competition on Twitter where people vote for their favorite development boards. We are now at the quarter finals, and beside the usual suspects such as Raspberry Pi and ESP8266 boards, I also noticed one board that I had never heard of: AXEL Elettronica’s SmartEverything based on Atmel SAM D21 Cortex M0+ and featuring SigFox, BLE, NFC, and GPS connectivity, as well as various sensors such as humidity and temperature, 9-axis motion sensor, and so on.

$15 RobinCore WiFi IoT Module Runs OpenWrt, Supports 720p Video Encoding (Crowdfunding)

Do you remember VoCore? It was a low cost OpenWrt WiFi IoT module based on Mediatek RT5350 processor, that had a very successful crowdfunding campaign managed by a single developer, and the project is still going strong with VoCore2 being in the works. Another developer had the idea of doing something similar but based on HiSilicon Hi3518 ARM9 processor with more memory and support for 720p video encoding making it suitable for HD drone camera, compact video cameras, and so on. Meet RobinCore.

Imagination Releases OpenWrt and LWM2M Stack Source Code for MIPS Creator Ci40 Development Board

MIPS Creator Ci40 is a development board made by Imagination technology that features the company’s Creator cXT200 “Pistachio” SoC with a dual core MIPS interAptiv processor @ 550MHz and Ensigma C4500 RPU for 802.11ac/ BT 4.1 LE connectivity. The boards are supposed to be shipped to Kickstarter backers in April, but in the meantime, the company has released the source code for OpenWrt distribution as well as LWM2M stack for the board. OpenWRT source code is available in OpenWrt repo in FlowM2M gitbub account. Building the code for MIPS Creator Ci40 is quite straightforward:

Select IMG MIPS Pistachio in make menuconfig, save the settings, and then run make to build OpenWrt for the board. This will also build the toolchain, so you don’t need to install any before hand. LWM2M stands for Lightweight Machine to Machine, and is a protocol from the Open Mobile Alliance (OMA) for M2M / […]

M2.COM is a Standard for IoT Sensors Based on M.2 Form Factor

The IoT ecosystem really feels like a jungle now, not because of a lack of standards, but because everybody thinks about doing their own, so we’ve ended up with a wide range of communication protocols, initiatives, and consortia, and it will take some time until the winners and losers are sorted out. One the of the latest standard is M2.COM platform form factor for sensors that “adopts the standardized M.2 form factor and is defined as an evolutionary module that combines general wireless connectivity with additional built-in computing ability powered by MCU”. M2.COM architecture diagram above describes both software and hardware requirements, but the specifications themselves only define the form factor, as well as mechanical and electrical characteristics: Consistent with M.2 standard Module size: 22 mm x 30 mm PCB thickness: 0.8 mm ± 10% Pin count: 75 pins Module input voltage: 3.3V DC-in Connector mating force: 30N Maximum Connector […]
