TeraRanger I2C Adapter

30.00 (VAT included)
25.00 (ex. VAT)

The TeraRanger I2C adapter allows easy connection of TeraRanger One to an I2C port or hub and takes care of voltage level translation and of supplying the TeraRanger sensor with power. Compatible with 3S or 4S LiPo batteries (12-16V).

We developed this for direct use with Pixhawk and APM flight controllers via the I2C bus. Once connected to the flight controller the TeraRanger sensor is automatically recognized by the autopilot firmware.

N.B. All TeraRanger One sensors from serial number 1512 xxx and above are ready for operation with I2C. For serial numbers 1508 xxx and lower it is necessary to flash an I2C specific firmware to your sensor. This is available free of charge. Send an email to support@teraranger.com with your sensor serial number(s) requesting the I2C firmware and we will email it to you. Then use your TeraRanger USB adapter to flash the I2C firmware to your sensor.

In the box:

  • I2C adapter board with power management system (requires soldering +/- power cables)
  • cable from adapter board to TeraRanger One sensor

 Quick setup instructions for Pixhawk with APM:

  1. solder power cable (3S or 4S, 10-20V) to the adapter paying attention to the non-marked polarities (+ and -), please see this in picture 2 above
  2. connect the provided cable between the adapter and the TeraRanger sensor. (If required, ensure you have installed the I2C firmware version to your sensor.)
  3. connect the other side of the adapter to the Pixhawk I2C port. (You will have a spare compatible cable already in your Pixhawk pack. NB: if you have something else connected to the I2C port on the Pixhawk, you can add a little I2C hub, which is also provided with the Pixhawk. Refer to picture 3 above.)
  4. ensure that you have updated to the latest APM firmware
  5. in Mission Planner you can now enable the use of TeraRanger One by selecting the use of “sonar” and select PX4 type. (In future versions we will update this to make it easier to select)
