Brief Synopsis: This tutorial demonstrates how to set up an I2C circuit using a Raspberry Pi product such as the classic Raspberry Pi, Raspberry Pi Zero, Raspberry Pi 2, or Raspberry Pi 3 and an I2C Sensor MaxSonar. You can plug the 40-pin GPIO cable between the Pi computer and the Pi GPIO Breakout Board. Ask Question Viewed 816 times 0. 3V on pin 1 using a resistor. To enable it, you'll need to manually edit the configuration file. Info Provides information on this Raspberry Pi's CPU and form factor. A 4-node Raspberry Pi Cluster. The new GrovePi+ is CE certified and compatible with Linux and Win 10 IoT. After connecting to the board, you can use mypi to interact with the Raspberry Pi board and peripheral devices. 3v working voltage. HMC5883L magnetometer to Raspberry Pi connection notes Some quick notes for connecting Honeywell's 3-Axis Digital Compass IC HMC5883L to the I2C bus on a Raspbrry Pi board. For the example, one pole of a push-button has been connected to Pin 12 on the Pi's connector (corresponding to GPIO pin 18 of the BCM2835 SOC) and via a 10k Ohm pull-up resistor with pin 1 (+3. 4GHz and 5GHz wireless LAN, Bluetooth 4.
