One of the best things about Beaglebone Board is the massive accessible GPIOs coming out from its 2x 46 pin headers. However, as we know, all things has two sides - the good side and the bad side. 2x46 pins means 2x46 jumper wires, and 2x46 jumper wires putting on the board means – A REAL MESS. How can a rapid prototyping be called ‘rapid’ if you spend most of your time dealing with entangled wires? Now this Grove Base Cape for Beaglebone v2.0 is designed for real rapid prototyping with your Beaglebone board.
The cape has brought the simplicity of Grove system to your Beaglebone projects, just attach it directly onto your Beaglebone v2.0, and then you can have 12 easy-to-use Grove connectors to do plug-and-play with the big family of Grove modules. The connectors include 2x UART, 2x ADC, 4x Digital I/O and 4x I2C that interface to the pins on your Beaglebone board, offering almost everything you need. There are two switches used to reset the I2C address in case of address conflicts. The board also integrates a switch for voltage transition - from a normal 5V to 3.3V.

Change the Grove button Signal pulldown resistance 10k to 1k.Let us know the results.
Please download schematic from the following link http://wiki.seeedstudio.com/wiki/File:Grove_Base_Cape_for_BeagleBone_v2.0_Schematics.zip.
thanks for the schematic and tips Law Yan and kavi.
I changed the 10K resistor in Grove button to 1K and it's working. (please check the .sch file, I think it's empty)
Now I have the same problem with a AM2302 sensor. I can't use 1-wire throu the Grove Beaglebone Cape
When use the Grove cape (GPIO_115) not work but when I use another GPIO without the TXB0108PW works and I can read de values.
