      Hi,
      what is recommended way of connecting I2C device consuming up to 85mA to UniPi 1.1?

      Let's say I want to connect LiDAR Lite V3HP sensor to UniPi 1.1 over I2C Rj11 interface.

      Would you recommend to use +5V from RJ11?

      Or rather use external power-supply?

      Thanks for answer in advance:)!

        Hi,

        You can use power from the I2C connector for this current. The 5V pin in the I2C connector is directly connected to the 5V power supply from the DC connector.

        If you want to be sure, use the capacitor (1000 μF) mentioned in the article on the sensor.
