BeagleBone core modules: the electronics engineer's best friends
BeagleBone minicomputers are excellent examples of how modern embedded systems should be designed. The different main modules differ in the choice of main components - such as processor, memory or communication modules - as well as in the number and type of embedded connectors, the number of USB ports, the power supply, and the circuits and peripherals offered. The simplest and most affordable version available in our shop, PocketBeagle, is powered by a powerful processor from Texas Instruments - AM3358 from the Sitara family, equipped with a 1 GHz ARM Cortex-A8 core, cooperating with 512 MB RAM. The board is programmed from a web browser, which allows you to freely experiment with it, without worrying about damaging the operating system - if necessary, you can easily restore the whole thing to its factory state. Any extensions can be connected to the device via two 36-pin goldpin connectors, while the power supply is provided by a micro USB socket. You should also check out the accessories and add-ons available in our shop.
Connectors, add-ons and other
If you need an Ethernet connection for your application, choose the BeagleBone Green board. It also offers 4GB of on-board Flash memory, two connectors accepting Grove standard expansions, a USB A connector and - like PocketBeagle - two fast 32-bit real-time PRUs clocked at up to 200 MHz. The higher model in the series - BeagleBone Green Wireless - also offers 3 additional USB A connectors, an IEEE 802.11b/g/n WiFi module and Bluetooth Low Energy (BLE). The Green series main modules offer two 46-pin connectors each, so any external devices and extensions will be able to be connected without the need for pin-out expanders.
One picture is worth a thousand words
One of the most advanced versions - the BeagleBone Black Wireless - in addition to the peripherals familiar from the Green version, features a micro HDMI port which, in combination with a built-in 3D graphics accelerator, allows support for monitors with resolutions up to 1440x900 pixels. The HDMI output also supports digital audio transmission, while computationally intensive operations are greatly accelerated by the built-in NEON floating-point coprocessor. BeagleBone Black main modules offer real-time system support with two PRUs available for developers.
