Grove Base Cape for BeagleBone® v2 Description
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. 2×46 pins means 2×46 jumper wires, and 2×46 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.
Features
- 12 Grove Connectors includes
- 2x UART
- 2x Analog Input
- 4x Digital I/O
- 4x I2C Interface
Hardware overview
Output voltage switch, is a switch to control output voltage to Grove ports.
USER button, is a button that can be used as BeagleBone® USER button.
Cape address switch, is a switch to choose cape address (only useful when multiple capes are attached) to avoid I2C address collision. For details about using more capes, please visit https://beagleboard.org/Support/bone101/#capes and http://elinux.org/BeagleBone_Community#Capes. You can use this switch to choose address from 00(binary, pulled down for factory setttings) to 11(binary, on Grove Base Cape for BeagleBone v2) which correspond to 0x54 to 0x57 for all capes.
Write protection pin, is used to disable write protection of EEPROM of a cape if those pins are connected. By default, it is not connected.
LMV324 operational amplifier, is a low-voltage rail-to-rail output operational amplifiers to control analog voltage. Read more
TXB0108PW, is an 8-bit bidirectional voltage-level translator. Read more.
Note you can find two notch(round corner with holes) on one end of Grove Base Cape for BeagleBone® v2.0. This end corresponds to the end with same notch on BeagleBone® Green. You can use this notches to ensure proper orientation.
Get started
In this section, we will show you a basic example to use this board. You can find more demos at BeagleBone® Recipes page. Just append Grove Base Cape for BeagleBone® v2 to those projects to make wire connection convenient.
