Sensor networks are the way to go if you have to monitor environmental data such as temperature in a wide area. Usually you need some infrastructure, including servers for communication, data storage, and the like and to manage the network and make the sensor data available. This session shows how you could build a sensor network, including the infrastructure, based on embedded devices only. It uses several embedded devices such as a Raspberry Pi, a BeagleBone Black, a Cubieboard2, and an i.MX6-based Cubox-i. The idea is to use cheap standard devices in combination with Java technology to realize a sensor network. In addition, it shows mobile clients, such as a smartwatch, for visualizing the sensor network data.

BeagleBone Black Wireless hurries up development

When you’re thinking of development boards, ia bukan hanya mengenai Arduino dan Raspberry Pi. The BeagleBone Mesra TI adalah terdapat dalam campuran, terlalu, struggling for your attention

Which is a justified reason to talk about some developments around the BeagleBone Black single-board computer: ada versi baru dan 2 Capes baharu daripada pasukan BeagleBone yang.

Serta BeagleBone Black Wireless (listed below), anda juga akan mendapati 2 brand new ‘cape’ add-on boards for the existing BeagleBone Black.

BeagleBone Black Wireless

Foremost, the BeagleBone Black Wireless, which is for the most part a BeagleBone Black with on-board 802.11 b / g / n 2.4GHz Wi-Fi serta Bluetooth. Ia berikut dalam laluan Raspberry Pi 3 by building in Wi-Fi support to streamline wireless communications.

Janakuasa adalah Texas Instruments Sitara AM3358 1GHz ARM Cortex-A8

"Sama seperti BeagleBone Black, wayarles mengekalkan output HDMI, port debug siri, PC antara muka USB, USB 2.0 pihak, menetapkan semula dan butang kawalan kuasa, dan membawa 2 more status LEDs for WiFi and also Bluetooth,"Menyatakan BeagleBone.org.

“Also kept is the 4GB of on board eMMC memory with Debian Linux preinstalled, enabling the BeagleBone Wireless to boot in approximately Ten seconds and have you developing through the browser in fewer than Five min’s making use of simply a single USB cable.”

You can look at the specifics of the board by expanding the graphic above, and a data sheet is the following for download.

Considering that we’re speaking about plastic card-sizes peices of kit, space is required to be made for extra features. This in essence means this particular BeagleBone has displaced its 10/100 port Ethernet, menghasilkan ruang untuk TI WL1835 WiLink wi-fi antara muka.

Tidak lupa juga dua capes baru ...

Wireless Cape addon

Notice that the new Wireless Cape takes BeagleBone Black above the abilities of BeagleBone Black Wireless, points out Steve Bush in his news piece on the release. It’s powered by Texas Instruments WiLink 8 (WL1837) industri dual-band (2.4GHz & 5GHz), 2× 2 MIMO Wi-Fi, Bluetooth dan Bluetooth Smart (otherwise known as Bluetooth LE), that also comes with Zigbee and NFC.

The cape unfolds with Debian Distribution pre-installed and 4GB of on board eMMC Flash memory. “Designers might be developing employing their browser in less than Five min’s by means of just one single USB cable,"Kata Farnell.

Paparan cape addon

Note there’s yet another Display cape addon sold. It provides connections for a 4.3in. color touch-screen an LED backlight and capacitive overlay “for a mobile-like interface”.

The cape is aimed at interactive projects, sistem terbenam dan set up berdiri sendiri.

Rates

Pricing is approximately £55 for the BeagleBone Black Wireless, £35 for the display cape addon as well as, £44 for the wireless cape addon .
