réseaux de capteurs sont la voie à suivre si vous devez surveiller les données environnementales telles que la température dans une vaste zone. En général, vous avez besoin d'infrastructure, y compris les serveurs de communication, stockage de données, et similaires et de gérer le réseau et rendre les données de capteurs disponibles. 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. en outre, 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, il est non seulement sur l'Arduino et Raspberry Pi. Le BEAGLEBONE TI convivial est là dans le mélange, aussi, struggling for your attention

Which is a justified reason to talk about some developments around the BeagleBone Black single-board computer: il y a la nouvelle version et 2 nouvelles Capes de l'équipe BEAGLEBONE.

Ainsi que le BEAGLEBONE sans fil noire (listed below), vous trouverez également 2 brand new ‘cape’ add-on boards for the existing BeagleBone Black.

BEAGLEBONE sans fil noire

Foremost, the BeagleBone Black Wireless, which is for the most part a BeagleBone Black with on-board 802.11 b / g / n Wi-Fi 2,4 GHz ainsi que le Bluetooth. Il est en suivant la route du Raspberry Pi 3 by building in Wi-Fi support to streamline wireless communications.

Son groupe motopropulseur est le Texas Instruments AM3358 Sitara 1GHz ARM Cortex-A8

« Tout comme le noir BEAGLEBONE, le réseau sans fil maintient la sortie HDMI, port de débogage série, Interface USB PC, USB 2.0 hôte, réinitialisation et boutons de commande de puissance, et apporte 2 more status LEDs for WiFi and also Bluetooth,» Déclare 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.

Prendre note qu'il marque l'introduction du Octavo OSD3358 SiP, l'intégration des fonctionnalités de BEAGLEBONE dans un boîtier 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 port Ethernet, produisant un espace pour une interface Wi-fi TI WL1835 WiLink.

Sans oublier les deux nouvelles capes ...

addon sans fil Cap

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) industriel bi-bande (2.4GHz & 5GHz), 2× 2 MIMO Wi-Fi, Bluetooth et Bluetooth intelligent (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,» Dit Farnell.

Affichage addon cape

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, systèmes embarqués et autonomes ups ensemble.

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 .
