GrovePi+ is a cap that allows you to connectGrove sensorsto the Raspberry Pi. This is a newer version of the GrovePi overlay, adding the ability to operate the RaspberryPi Model B+ and Model A+. It has three mounting holes to fit each version of the Raspberry Pi. The cover plate also has a hole for camera cable. It also improves the conversion of the voltage level of the slaves.

Connect GrovePi to Raspberry Pi
Start by installing GrovePi on Raspberry Pi. GrovePi slides on top of Raspberry Pi as shown in the picture below.
Make sure that the pins are properly aligned when applying GrovePi.
Configure the Raspberry Pi software
Now it is time to install the software on Raspberry Pi. There are two installation options:
-
use your own BrickPi Image.
-
If you already have your own Linux distribution running on Raspberry Pi you can use our bash script to install GrovePi.
Use BrickPi Image
-
Download Brick Pi Image and install the system compilation on the SD card. Here is a link tothe BrickPi page with instructions on how to configure the SD card. You will need at least a 4GB card to perform this installation.
-
copy the Github repository to the appropriate location in Raspbian
git clone https://github.com/DexterInd/GrovePi.git
-
Run bash script in Scripts folder and configure Raspbian. Here is a tutorial on how toconfigure with the script.
-
Restart Raspberry Pi.
Configure your own system compilation
- copy the Github repository to the appropriate location
git clone https://github.com/DexterInd/GrovePi.git
-
Run bash script in Scripts folder and configure Raspbian. Hereis a tutorial on how to configure with the script.
-
Restart Raspberry Pi and you can start using Grove Pi.
Testing GrovePi
Once you've configured your Raspberry Pi to work with GrovePi, it's time to check the action!
We have developed three simple projects to demonstrate how GrovePi works.
