New UART to WIFI chipset will unleash low cost Internet of Things

ESP8266_Wi-Fi_Module

WiFi infrastructure is everywhere which makes easier to make network of devices connected to WiFi.
There is also great range of WIFI routers with different space coverage and speeds, and as they are mass produced product the prices are at the rock bottom if we have to compare to Zigbee or Bluetooth.
WiFi stack require resources though and not quite good for smallish 8bit populary hobby processors, this is why UART-to-WIFI solutions were made and become popular.
Texas Instruments released CC3000 which cost about $20-25 in single quantities and $10 in volume.
It took no longer and Chinese company Espressif released their ESP8266 highly integrated UART-WIFI bridge IC, it requires just quartz crystal and balun to make WIFI module, their reference design is with just 11 x 12 mm board space!
And of course this comes at Chinese prices: you can buy ESP8266 module in single quantity from Seedstudio for $6.95 or from Alibaba for $5!
On top of this you can easy connect devices to Internet and send and receive data through UART!
This will definitely wipe out the $50-60 Arduino WIFI shields and even Microchip’s MRF24WB0MA etc modules.

We are going definitely to release MOD-ESP8266 which to connect to all our boards with UEXT and give possibility to connect to Internet with simple AT commands!
With MOD-IO2+MOD-ESP8266 for instance anyone could make WIFI enabled relay and Inputs and monitor through web page the inputs and drive relays for extremly low cost!

Who fears from the competition? RPi Foundation pressed Broadcom to stop selling BCM2835 to competing projects.

Odroid

On July 29th I blogged about the Raspberry Pi Clones which now exist and the new Odroid project which actually makes better hack friendly module based on BCM2835 including better power supply, LiPo battery support etc features.

This is pure example that no matter if your project is open or closed hardware it could be cloned if there is enough interest to do so.

Also I made speculations that due to the bad financial condition which Broadcom faces due to the Chinese SOC competitors they start selling their BCM2835 to anyone with money.

Well this must have upset RPi Foundation a lot and they should have start to pess Broadcom about stop selling the BCM2835 to others than RPi.

Today Odroid guys wrote on their G+ account: “We have to stop ODROID-W project soon since Broadcom will not supply the SoC to Hardkernel anymore.
When the first trial batch is sold out, you can’t buy the ODROID-W anymore. Sorry for the inconvenience.”

We got this note via Twitter: Reinis Veips made his own Open Source Hardware laptop using broken laptop as base for LCD and keyboard and connected them to A10-OLinuXino-LIME  + SATA drive :) You can read about his project here.

HowTo setup A20-OLinuXino-MICRO RootFS on SATA and ownCloud

ownCloud

fromcologne posted on our forum interesting tutorial how to setup rootfs on SATA drive and to setup your own cloud service with A20-OLinuXino-MICRO.

Now you can keep all your work files, pictures, movies to your own Cloud storage service and have access to them via your phone, laptop, tablet etc devices.

Good work!
