|Raspberry Pi Camera V2 released|
April 25, 2016
Author: Nikolai K.
The Raspberry Pi foundation released their camera V2 today. The original camera was released in 2013, but the OV5647 sensor was discontinued at the end of 2014 and all the cameras sold since were from large stockpiles.
This new camera has a Sony IMX219 8-megapixel sensor with a fixed focus and retails for $25 USD. The maximum still-picture resolution of this new sensor is 3280 X 2464 pixels and support a image transfer rate of 30 fps for 1080p and 60 fps for 720p. The V2 camera sensor comes as a visible-light and as a infrared-version (Pi NOIR) for the same price.
To clarify, all CMOS sensors detect infrared wavelengths called "near-infared", which are adjacent to the visible light spectrum. Regular visible light cameras come with an infrared filter on the sensor, which blocks these wavelengths thus allowing only visible light to be captured. The NoIR camera does not have this filter and is able to capture some of the infrared spectrum, which makes it useful for night photography or for scenes that are flooded with infrared light (by an infrared LED, for examples).

|UDOO x86 Kickstarter|
April 22, 2016
Author: Nikolai K.
UDOO currently has a Kickstarter campaign for what they call the most powerful Maker board to date: the UDOO x86 (compare to the original board here). This new board is advertised to be 10 times as fast as the Raspberry Pi 3 and the Basic board starts at $89 with an expected delivery date of November 2016.
The board is powered by an Intel Quad-Core processor (up to 2.0 GHz for Basic, up to 2.24 GHz for Advanced, and up to 2.56 GHz for the Ultra board). The Basic board comes with 2 GB of RAM and the higher cost models are slated to have 4 GB of RAM. The board has 8GB eMMC flash memory storage, but has a SATA and an M.2 connector for additional hard-drives. The UDOO x86 comes with Gigabit Ethernet, Wi-Fi 802.11ac and Bluetooth Low Energy connectivity.
The UDOO is a powerful single board computer with an Arduino 101-compatible GPIO pinout, which makes it compatible with all Arduino 101-compatible shields, sketches, and libraries. The board has a 6-axis accelerometer and gyroscope. A cool feature is the interconnectivity of the Arduino and the Quad-core processor, which allows the low-power consumption Arduino to start and wake up the high power consumption computer portion, which can potentially extend battery life for your IoT (Internet of Things) device as it allows your computer to react to the environment only when required to.
Currently, the Kickstarter campaign is fully funded and has over 1 month left to go and can be found here. As always, keep the potential dangers and delivery problems of crowd-funding campaigns in mind.
|The Intel Up Board, Raspberry Pi 3 alternative|

The Intel Up Board, Raspberry Pi 3 alternative
The Intel Up Board (created by Aaeon Europe) is said to start shipping in May. Pre-orders are accepted for an UP board outperforms the Raspberry Pi 3, but this additional performance starts at a cost of $89 USD.
The UP board features a quad-core Intel Atom x5 Z8350 64-bit 1.92Ghz processor with 2 GB DDR3L RAM (the shop does offer 1GB, 2GB, and 4 GB options). It has 16 GB eMMC Flash for on-board storage (32 GB and 64 GB options are available) and Intel HD 400 Graphics.
The board features an HDMI connector, four USB 2.0 connectors, two USB port pin headers, and one USB 3.0 USB OTG connector. The UP board comes with an internal real-time clock (RTC), which is rarely seen on other single board computers. The UP Board has the same form-factor as the Raspberry Pi 2 and has 40 GPIO pins. The Raspberry Pi 3 is cheaper and comes with built-in wireless communication. The UP-board currently only has an Ethernet connection.
The board is available for pre-order at the UP-shop.org.
