This product is retired, please consider our GrovePi+ as your alternative choice.
Power the Arduino side with Raspberry power or with external power.
Selectable Arduino side power with 5V or 3.3V
FTDI cable connector to be able to program Arduino independently leaving RX/TX of arduino and Raspberry free.
Power level shifter between Pi side and Arduino side for I2C, SPI, Serial, and all Raspberry Pi GPIO pins
Raspberry Pi board Revision 2 with four new GPIO
I2C Bus available from Arduino and/or Raspberry Pi
I2C to 1-Wire controller on the board providing fully OWFS (or other) support for Raspberry Pi or Arduino with dedicated library
Feature to connect I2C between Arduino And Raspberry Pi (Arduino will become a I2C slave from Raspberry Pi)
Feature to connect SPI between Arduino and Raspberry Pi (Arduino will become a SPI slave from Raspberry)
Feature to connect the Arduino UART to Raspberry Pi Serial to do communication
Availability to use the French dedicated Téléinformation monitoring electricity signal issued from the main power meter to Arduino or Raspberry Pi (using serial RX)
Grove connector on board for I2C and Serial connection for Raspberry and Arduino
Sized place to plug aAdafruit I2C or SPI Oled breakout board that can be driven by Arduino or Raspberry Pi in SPI or I2C
Sized place to plug a NRF24L01 Wireless breakout board. In the near future, some breakout board fitting this format will be available for RFM12B RFM69W, SD card and SPI flash memory. This will let you use the majority of RF module used today
Sized place for 3 x 1-Wire devices on board.
Sized place for using PWM devices (switchable with on board power or external power)
Two free pins available on level shifter chip, this mean that is you have a device that need level conversion between 3V3 and 5V in both way, you have two pins left for this.
Compatible with Raspberry Pi A+,B,B+.
