The board is designed and manufactured by Seeed Studio, and the company send me an early sample for evaluation together with Grove Base Cape for Beaglebone v2.0 that supports up to 12 extra Grove modules. I’ve not had time to review both yet, so I’ll show what I’ve received first.
I got the two antennas, but not the USB cable. There are two u.FL connectors where you can insert the antennas. The wireless module is Texas Instruments WiLink8 (model WG78V0) that supports WiFI 802.11 b/g/n @ 2.4 GHz 2×2 MIMO and Bluetooth 4.1 LE. The four USB ports are on the left, and two Grove connectors (I2C & UART) on the right.
The bottom of the board has the micro SD slot, micro USB port for power, and unpopulated 20-pin JTAG solder pads. The board can run Debian, Android, Ubuntu, Cloud9 IDE on Node, and all other operating systems supported by BeagleBone Black. The wireless module support AP+STA mode, as well as A2DP & MRAA Libraries. The board is shipped with a Debian based firmware, and you can easily access it by accessing http://192.168.8.1 from your computer web browser to get some documentation. Resources for the board can be found on the BeagleBone Green Wireless Wiki.
Grove Base Cape for Beaglebone v2.0 has 4x digital I/O headers, 2x analog input headers, 4x I2C headers, and 2x UART headers, as well as a I/O voltage selector (3.3V or 5V), a Cape address switch, and a user button. More details about the grove base cape can be found in the Wiki.
I plan to write test the board, and the cape with some of the Grove module I got in Wio Link Starter Kit in the next few days.
