The Raspberry Pi Foundation recently introduced a $10 Pi Zero W which resembles the $5 single board Pi Zero computer it launched in 2015 but adds built in Wi-Fi and Bluetooth radios.
At the heart of the Raspberry Pi Zero W is a 1GHz single core Broadcom BCM2835 application processor and 512MB of RAM. Storage is handled by s micro SD card slot. The tiny board includes the following I/O options:
- 1 x Mini HDMI
- 1 x Micro USB OTG
- 1 x Micro USB for power
- 1 x 40-pin HAT compatible header
- 1 x CSI camera connector
- 1 x Composite video header
- 1 x reset header
The Pi Zero W uses the same Cypress CYW43438 chip as the Pi 3 Model B and offers 802.11n Wi-Fi and Bluetooth 4.0. According to the Raspberry Pi Foundation, they found that many users were using USB wireless dongles along with a HID (keyboard/mouse) and they needed to carry around a hub or integrate it into their project. Adding built in wireless frees up the single Micro USB port for ither devices and hopefully allows smaller devices that use a Pi Zero as its brains.
Per RasPi.TV’s testing, the new Pi Zero W uses approximately 20mA more power than the Pi Zero which the site attributes to the wireless radios. While it more power than the previous model it is still half that of the Raspberry Pi 3 B. Specifically, the Pi Zero W pulls 120mA at idle and up to 170mA when playing back a 1080p video. Recording 1080p video from a camera uses ~230 mA. The SBC is rated at 0.6W to 1.2W (120 to 230 mA at 5.19V).
A modular official case is being released alongside the new board. US residents will be able to pick up the $10 single board computer at Adafruit, CanaKit, and Micro Center.
The Pi Zero has been used in a large variety of projects including robotics, arcade games, home automation and motion sensing cameras IoT, information displays, and electric skateboards. Integrating the wireless radio should make similar projects just a bit easier to out together.

The Raspberry Pi Compute Module 3 is a pin compatible successor to the Compute Module 1 (there is no CM2) that, according to the Raspberry Pi Foundation, offers twice the RAM and 10-times the CPU performance.
Note that while the Compute Module 3 may be able to be a drop in upgrade / replacement for devices powered by the first generation CM1, it uses more power, puts out more heat, and is 1mm taller so while it is pin compatible it may not work in all devices if their module slot space, power supply, and airflow / heatsinks are not up to the task.
The Compute Module 3 is a small single board computer with a SO-DIMM connector that can slot into embedded and IoT products. It is powered by a Broadcom BCM2837 with four ARM Cortex-A53 CPU cores clocked at 1.2 GHz and a dual core VIdeoCore IV GPU clocked at 400 MHz. The processor is paired with 1GB of RAM. As far as onboard storage, the Compute Module 3 will come in two SKUs: the CM3 with 4GB of eMMC or a CM3 Lite without pre-installed eMMC and solder points for manufacturers to add their own eMMC or micro SD card slot. The VideoCore IV GPU supports 1080p30 decode of H.264. Users wanting hardware decode of H.265 and/or 4K support will have to look elsewhere. As is usual with Broadcom, exact specifications of the BCM2837 (especially their GPU) are kept close and quiet, unfortunately.
The exact ports and I/O from the Compute Module 3 will depend on the device and what manufacturers implement and wire to the connectors on the SO-DIMM slot. However, looking at the CMIO3 development board (96 Euros, $116 USD) shows that the CM3 supports GPIO, USB, micro USB, CSI (camera interface), DSI (display interface), HDMI, micro SD, audio, and networking.
The Compute Module 3 can run Windows IOT Core or any number of Linux distributions compatible with ARM processors.
The Compute Module 3 is $30 while the “lite” variant without eMMC is $25. A kit including the development I/O board and both CM3 SKUs is $200. NEC has already announced it will be using the new Compute Module 3 in their digital signage and displays. Other applications include Smart TVs, home automation, and industrial control systems as well as hobbyist projects and robotics.

Asus has officially launched the RT-AC5300, a massive
replicator tri-band wireless router. The new router is fenced in by eight large antennas that allow the device to support 4 x 4 MU-MIMO wireless on two 5 GHz and one 2.4 GHz bands.
The menacing high-end wireless router supports the latest wired and wireless consumer networking technologies and runs the AsusWRT firmware. The RT-AC5300 is clad in black with red accents. The top of the router is mesh to facilitate cooling. In addition to the eight antennas, there are five gigabit Ethernet ports (up to two ports can be configured as WAN ports), a USB 3.0 port, one USB 2.0 port, and physical buttons for WPS, Wi-Fi, and LED on/off.
Powered by a Broadcom chipset, the router supports 802.11ac as well as older N/G/B Wi-Fi standards. Using NitroQAM technology, the two 5 GHz bands each support up to 2,167 Mbps speeds while the 2.4 GHz band tops out at 1,000 Mbps. This is a boost over the usual 1,734 Mbps for 5 GHz and 600 Mbps for 2.4 GHz wireless bandwidth numbers. Asus claims that the router can run all three bands simultaneously along with beamforming to improve the signal to devices by focusing the signal. Note that the combined advertised "5334 Mbps" of the router includes all three bands but a single device would max out at the 2,167 Mbps theoretical maximum of a single band. The router is capable of automatically figuring out and using the optimal band to communicate with each device based on its capabilities and signal strength.
When it comes to wired connections, the router has four 1 Gbps LAN ports. It also supports 802.3ad link aggregation which allows using two of the gigabit ports to create a single 2 Gbps link to supported devices like network attached storage (NAS) and workstations.
Asus is using ASUSWRT firmware along with AiRadar beamforming, AiProtect security, and a subscription to WTFast GPN which is a service aimed at gamers that reportedly delivers decreased pings and lower latency connections to game servers.
Pricing and availability have not been announced, but CNET is reporting an expected price of $400 USD.
To say that this router is overkill for most is an understatement, but it is packed with features and is ready to stream a Stargate SG-1 marathon to all your devices!

Josh Walrath titled the intro of his "Next Gen Graphics and Process Migration: 20nm and Beyond" editorial: "The Really Good Times are Over". Moore's Law predicts that, with each ~2 year generation, we will be able to double the transistor count of our integrated circuits. It does not, however, set a price.
A look into GlobalFoundries.
"Moore's Law is expensive" remarked Tom Kilroy during his Computex 2013 keynote. Intel spends about $12 billion USD in capital, every year, to keep the transistors coming. It shows. They are significantly ahead of their peers in terms of process technology. Intel is a very profitable company who can squirrel away justifications for these research and development expenses across numerous products and services.
The benefits of a process shrink are typically three-fold: increased performance, decreased power consumption, and lower cost per chip (as a single wafer is better utilized). Chairman and CTO of Broadcom, Henry Samueli, told reporters that manufacturing complexity is pushing chip developers into a situation where one of those three benefits must be sacrificed for the other two.
You are suddenly no longer searching for an overall better solution. You are searching for a more optimized solution in many respects but with inherent tradeoffs.
He expects GlobalFoundries and TSMC to catch up to Intel and "the cost curve should come back to normal". Still, he sees another wall coming up when we hit the 5nm point (you can count the width or height of these transistors, in atoms, using two hands) and even more problems beyond that.

From my perspective: at some point, we will need to say goodbye to electronic integrated circuits. The theorists are already working on how we can develop integrated circuits using non-electronic materials. For instance, during the end of my Physics undergraduate degree, my thesis adviser was working on nonlinear optics within photonic crystals; waveguides which transmit optical frequency light rather than radio frequency electric waves. Of course I do not believe his research was on Optical Integrated Circuits, but that is not really the point.
Humanity is great at solving problems when backs are against walls. But, what problem will they try?
Power consumption? Cost? Performance?

As reported earlier, the Raspberry Pi is a small computer intended to run Linux and is made to be portable and able to be powered by USB. The small board is based on the Broadcom BCM2835 chipset, which includes an ARM 11 CPU and a dual core VideoCore IV graphics card co processor. The Raspberry Pi further includes connections for HDMI, component output, and USB ports. The higher tier $35 model will further feature an Ethernet jack and twice the RAM (512 MB).
The Raspberry Pi will soon be available for sale and if the company behind the device- The Raspberry Pi Foundation- is to be believed, the GPU in the little Linux computer will pack quite a punch for its size (and cost). In a recent Digital Foundry interview with Raspberry Pi Executive Director Eben Upton reported on by Eurogamer, Upton made several claims about the Raspberry Pi’s graphics capabilities. He explained that the Broadcom BCM2835’s VideoCore IV GPU is a tile mode architecture that has been configured with an emphasis on shader performance. Upton said “it does very well on compute-intensive benchmarks, and should double iPhone 4S performance across a range of content."
The comparison to the iPhone 4S relates to his further claims that the Raspberry Pi GPU is the best on the market and can best both the iPhone 4S’s PowerVR (Imagination Technologies) based graphics and even the mighty Tegra 2 in fill rate performance. Rather large claims for sure; however, we do have some independent indication that his claims may not be wholly inflated. The coders behind XBMC, open source media center software that allows users to play a variety of media formats, have demonstrated their XBMC software running on the Raspberry Pi. They showed the Raspberry Pi playing a 1080p blu ray movie at a smooth frame rate thanks to the Broadcom GPU being capable of 1080p 30 FPS H.264 hardware accelerated decoding. You can see the Raspberry Pi in action in the video below.
The little Raspberry Pi is starting to look quite promising for HTPC (and even light gaming) use, especially for the price! At $25 and $35 respectively, the Raspberry Pi should see quite the following in the modding, enthusiast, and education community.
