barometric sensor for raspberry pi
Connect bmp280 pressure sensor to raspberry pi without soldering to pins or running jumper wires. This is not to be used on the raspberry running pypilot, because it uses the pins normally used for the IMU inertial sensors. It is useful if you have openplotter connecting to tinypilot, and pins available on this raspberry. I have tested this with openplotter.

mpu9255 inertial sensors raspberry pi

These inertial sensors with adaptor plugs directly into the raspberry pi GPIO 40 pin header using the first 10 pins. It provides the 9-axis IMU sensors needed for autopilot. It also provides pins for vcc, tx, rx, gnd for serial communication to motor controller.

These are already included in the tinypilot autopilot computer. They are also already included in the openplotter moitessier hat, so this is only needed if you have no sensors.

If you have a raspberry pi (typically running openplotter) and want to build your own autopilot computer, these offer a neat solution without jumper wires.

These sensors are also already tested to eliminate bad ones.

The mpu9255 attaches to the i2c bus address 0x68. From a console execute "i2cdetect -y 1" to verify it is working.

minimal weather sensors
Measures wind speed and direction as well as barometric pressure. Compatible with pypilot for wind-steering modes, and opencpn for display and data logging.

  • Output: nmea0183 to usb as virtual serial port
  • Output rate: 10hz wind, 1hz pressure
  • Precision: 0.1 degree wind direction, 0.01 millibar
  • Cable: micro usb (not included)

    This is the minimal version without display or enclosure. For a version with display and enclosure see: weather sensors with display

    The pressure sensor used is bmp280. This does not include the analog anenometer.. The actual anenometer is available from other sites such as:


    It is possible to build your own sensors using a potentiometer for wind direction, and a reed switch and magnet for wind speed. For more information about the davis anenometer see: http://www.lexingtonwx.com/anemometer/
