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 uzuza $50 4.3-intshi cap zokuthinta isikrini Cape
BeagleBone Black Wireless hurries up development
When you’re thinking of development boards, akusiwona nje mayelana Arduino futhi okusajingijolo Pi. I BeagleBone TI-friendly lapho ukuxubana, kakhulu, struggling for your attention
Which is a justified reason to talk about some developments around the BeagleBone Black single-board computer: there’s the new version and 2 new Capes from the BeagleBone team.
Kanye BeagleBone Black Wireless (listed below), you will also find 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 kanye-Bluetooth. It elandelayo umzila Raspberry Pi 3 by building in Wi-Fi support to streamline wireless communications.
powerplant yaso Texas Instruments sitara AM3358 1GHz asekelwe Cortex-A8
“Similar to the BeagleBone Black, the wireless maintains HDMI output, serial kokulungisa amaphutha port, PC USB interface, -USB 2.0 aphethe, kabusha nokulawula amandla izinkinobho, and brings 2 more status LEDs for WiFi and also Bluetooth,” states 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.
Take note that it marks the introduction of the Octavo OSD3358 SiP, zokuhlanganisa BeagleBone nokusebenza kwelinye iphakethe BGA.

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 i-Ethernet port, esikhiqiza isikhala okwesikhathi TI WL1835 WiLink Wi-Fi esibonakalayo.
:: AM335x 1GHz asekelwe Cortex-A8
:: SGX530 ihluzo namafutha
:: NEON elintantayo-iphuzu namafutha
:: 2x PRU 32bit 200MHz micro-controllers
:: WiLink 1835 802.11b / g / n 2.4GHz WiFi, I-Bluetooth, plus Bluetooth Smart Module
:: USB amaklayenti: amandla, kokulungisa amaphutha nedivayisi
:: USB aphethe
:: Micro HDMI okukhipha
:: 2x 46 pin izihloko
:: 512Megabyte DDR3 800Megahertz RAM
:: 4GB Inserted eMMC Flash with Debian Distribution pre-installed
:: Slot ikhadi sd micro
:: Cloud9 IDE ku Node.js w / umtapo BoneScript
Ukungazikhohlwa le capes ezimbili ezintsha ...
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) zezimboni-dual-band (2.4GHz & 5GHz), 2× 2 MIMO-Wi-Fi, I-Bluetooth ne-Bluetooth Smart (otherwise known as Bluetooth LE), ukuthi futhi iza Zigbee kanye 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,"Kusho Farnell.
Khombisa izimpawulo 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”.
ICape kuhloswe amaphrojekthi interactive, izinhlelo ashumekiwe ezimele iqoqo ups.
Pricing is approximately ￡55 for the BeagleBone Black Wireless, ￡35 for the display cape addon as well as, ￡44 for the wireless cape addon .
