BeagleBone Green SBC Offers LAN and Wi-Fi

Written by Eric Brown

Seeed has launched a new model in its line of BeagleBone compatibles that balances the feature sets of the $44 Seeed Studio BeagleBone Green and the $52.90 Seeed Studio BeagleBone Green Wireless. The $59.90 Seeed Studio BeagleBone Green Gateway provides the 10/100 Ethernet port of the BB Green along with the BB Green Wireless’ TI Wilink8 module with 2.4GHz 802.11b/g/n and Bluetooth 4.1 LE. The open spec board is equipped with 2x USB 2.0 ports instead of one port on the BB Green and 4x ports on the Wireless.

The BeagleBone Green Gateway was developed with the blessing of the Beagleboard.org community, which supports its flagship, $62 BeagleBone Black SBC and other compatibles. The SBC runs Debian, Ubuntu, or Android on the same 1GHz, Cortex-A8 TI Sitara AM3358 SoC found on the BB Black, Green, and Green Wireless, and other BeagleBone compatibles listed in our catalog of 136 Linux hacker boards. Loaded with industrial interfaces, the AM3358 offers dual programmable PRU real-time cores.

Like the first two BeagleBone Green models, the Gateway omits the micro-HDMI port of the BeagleBone Black and swaps out the mini-USB port for a micro-USB port. It also adds 2x Grove connectors for connecting Seeed’s I/O and sensor add-ons. Like all the BeagleBone models except for the COM-like PocketBeagle, the Gateway provides dual 46-pin GPIO extension connectors for plugging in Cape add-on boards.

Unlike the BeagleBone Black or the previous two Green models, the BeagleBone Green Gateway deploys its AM3358 and 512MB DDR3 via an Octavo Systems OSD335x-SM System-In-Package (SiP) module. This smaller version of the OSD335x SiP, which is used on the robotics-focused BeagleBone Blue, also powers the PocketBeagle.
