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. В додаток, 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, це не тільки про Arduino і Raspberry Pi. TI-дружній BeagleBone є в суміші, теж, struggling for your attention

Which is a justified reason to talk about some developments around the BeagleBone Black single-board computer: є нова версія і 2 нові накидки з команди BeagleBone.

А також BeagleBone Black Wireless (listed below), Ви також знайдете 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 б / г / п 2,4 Wi-Fi, а також Bluetooth. Це наступний в маршруті Raspberry Pi 3 by building in Wi-Fi support to streamline wireless communications.

Його силовий агрегат є Texas Instruments Sitara AM3358 1 ГГц ARM Cortex-A8

«Подібно BeagleBone Black, бездротовий підтримує вихід HDMI, послідовний порт налагодження, Інтерфейс USB PC, USB 2.0 господар, скидання і кнопка управління потужності, і приносить 2 more status LEDs for WiFi and also Bluetooth,»Заявляє 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.

Бездротовий Cape аддон

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) промисловий двохдіапазонний (2.4ГГц & 5ГГц), 2× 2 MIMO Wi-Fi, Bluetooth і Bluetooth смарт (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,»Сказав Farnell.

Показати накидка аддон

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, вбудовані системи і автономні встановлені вікна.

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 .
