What are the GPIO mapping to the GrovePi+ Ports


#1

I would like to know which GPIO pins made from the Raspberry Pi to each of the ports on the GrovePi+.

Example which GPIO pins go to D3, D4, I2C-3 etc.


#2

Hey,
The SPI pins GPIO 8,9,10 and 11 are connected directly to the GrovePi and are used to update new firmwares on the GrovePi.

The UART GPIO 14 adn 15 are connected to a Grove Port and can be used to connect a UART sensor directly to the Raspberry Pi.

The actual communications happen over I2C lines GPIO 0 and 1.

You can check the schematic here for more details: https://github.com/DexterInd/GrovePi/blob/master/Hardware/GrovePi%2B_2.2_schem.pdf . We also have a port description here: http://www.dexterindustries.com/GrovePi/engineering/port-description/.

Where can I find the GrovePI+ RPI_conn pin (GPIO Pin layout)? Please reference the 2 snip files.

Not sure if we understand what you’re looking for billh. Are you looking for a diagram that shows what each pin on the Pi header does?
