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. Inoltre, it shows mobile clients, such as a smartwatch, for visualizing the sensor network data.

BeagleBone Nero Wireless affretta lo sviluppo
Quando stai pensando di schede di sviluppo, non si tratta solo di Arduino e Raspberry Pi. Il BeagleBone TI-amichevole è lì nel mix, pure, che lottano per l'attenzione
Which is a justified reason to talk about some developments around the BeagleBone Black single-board computer: c'è la nuova versione e 2 nuovi Capes dal team BeagleBone.
Così come il Nero Wireless BeagleBone (listed below), puoi trovare anche 2 brand new ‘cape’ add-on boards for the existing BeagleBone Black.
BeagleBone Wireless Nero
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 nonché di Bluetooth. E 'seguendo il percorso del Raspberry Pi 3 by building in Wi-Fi support to streamline wireless communications.
Il suo propulsore è il Texas Instruments Sitara AM3358 1GHz ARM Cortex-A8
“Simile al BeagleBone Nero, il wireless mantiene uscita HDMI, porta di debug seriale, Interfaccia USB PC, USB 2.0 ospite, reset e pulsanti di controllo di potenza, e porta 2 more status LEDs for WiFi and also Bluetooth,”Afferma 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, e una scheda tecnica è la seguente per il download.
Prendere atto che segna l'introduzione del SiP Octavo OSD3358, integrando funzionalità BeagleBone in un pacchetto 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 porta Ethernet, producendo lo spazio per un'interfaccia Wi-Fi TI WL1835 WiLink.
Le specifiche tecniche complete:
:: AM335x 1GHz ARM Cortex-A8
:: acceleratore grafico SGX530
:: NEON virgola mobile acceleratore
:: 2x PRU 32bit 200MHz micro-controllers
Opzioni di connettività
:: WiLink 1835 802.11b / g / n 2.4GHz WiFi, Bluetooth, oltre a Smart Module Bluetooth
:: USB client: energia, debug e dispositivo
:: host USB
:: uscita micro HDMI
:: 2X 46 connettori maschio
:: 512Megabyte DDR3 800Megahertz RAM
:: 4GB Inserted eMMC Flash with Debian Distribution pre-installed
:: carta Slot micro sd
:: Cloud9 IDE su Node.js w / biblioteca BoneScript
Senza dimenticare i due nuovi capi ...
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. E 'alimentato da Texas Instruments WiLink 8 (WL1837) industriali dual-band (2.4GHz & 5GHz), 2× 2 MIMO Wi-Fi, Bluetooth e Bluetooth intelligente (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,”Ha detto Farnell.
Visualizzazione del Capo 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”.
Il mantello è rivolto a progetti interattivi, sistemi embedded e standalone allestimenti.
Pricing is approximately ￡55 for the BeagleBone Black Wireless, ￡35 for the display cape addon as well as, ￡44 for the wireless cape addon .
