New Raspberry Pi 4 is out, check out this image for the important features :
This version comes with desktop kit as accessory, next version may become a server?

New Raspberry Pi Model A+
Modified version of Raspberry Pi is out now, it is a cut down features of Model B, with some power boost on processing etc..
Azure IoT MCU Chip
Microsoft launched a new MCU that offers device connectivity to Azure platform with builtin security to offer a secure pipe for control and data communication..
Microsoft has fully embraced Unix with a variant as Kernel and calls it Azure Sphere OS!.
Produced by MediaTek, it is a single-core ARM-A7 running at 500MHz with Wi-Fi and other I/O connectivity options..
Amazon had a similar OS launch last year, It is OS alone with capability to run it on any chip that can be embedded into devices. Microsoft has gone one step further to test it with a particular chip also.
Who’s Next?
AI on a chip..
Seems to be getting some focus lately. Nvidia’s Volta, ARM’s Trillium, Intel with Nervana, Microsoft with Catapult and Google with TPU are the starting points for the silicon AI.
With comparisons to 80387, GPUs the AI in silicon seems to be suited for getting high speed analytics into edge devices if dedicated chips can help in reducing device footprint rather than using general purpose CPUs.
Computing at the size of salt!
IBM has announced smallest computer, the size of grain of salt.. Check it out here.
AWS Greengrass
So far it has been devices were reaching out to IoT Hub’s and Cloud and using the compute power for Edge and/or main computing apart from data handling, with AWS Greengrass it is reverse current!. You can use IoT and Lambda infrastructure that can trigger actions on devices that are connected via this framework and circuit is complete in terms of usage of the computing power in both directions apart from the existing bi-directional data transmission

Google IoT
Launched recently finally. It is catching up with AWS, Azure and IBM Bluemix and much later than PTC etc. But it has data for analytics that can propel it faster to realistic use cases deployment!.
Raspberry Pi – Zero W
Asus Tinkerboard – Better Video ‘Pi’
Asus has released a mini PC that is better in specifications for video rendering than Raspberry PI 3, a better Video ‘Pi’ for gaming and movie buffs!.
Comparison of Raspberry PI and Asus Tinkerboard is given below:
| Raspberry Pi 3 | Asus Tinker board | |
| Chip | Broadcom BCM2837 64-bit system-on-chip with four ARM Cortex-A53, 1.2 GHZ | quad-core, 1.8GHz Rockchip RK3288 SoC |
| GPU | Broadcom VideoCore IV | Mali-T674 |
| RAM | 1GB LPDDR2 (900MHz) | 2GB |
| Bluetooth | Bluetooth 4.1 Classic, Bluetooth Low Energy | Bluetooth 4.0 |
| USB | 4 USB 2.0 | 4 USB 2.0 |
| HDMI | 1 HDMI out | 1 HDMI Out |
| SD | microSD | microSD |
| Ethernet | 10/100 Mbps | GigE |
| Wi-fi | 2.4GHz 802.11n | 802.11 b/g/n |
| GPIO | 40 port | 40 port, 28 pin GPIO |
| CSI | CSI | CSI |
| DSI | DSI | DSI |

Raspberry Pi Goes Industrial..
After being the provider of consumer and IoT enthusiasts SoC compute/connect supplier, Raspberry has turned up a model for use in industrial applications.
It is just a compute module, with data pinouts similar to laptop memory sockets that can be programmed to take programmable I/O. It has same four-core, 64-bit Broadcom BCM2837 processor and 1GB of RAM as Raspberry Pi 3, half the size of it and doesn’t have ethernet, Wifi, USB, SD Card, Audio and Display.
NEC is already launching it’s large signage systems with this compute module. Interesting to see the Raspberry portfolio expanding.
