Hi @janis_blank , In theory yes, it's 3.3V TTL with 5V power supply on that connector. There are MAVLink baud rate settings and mode that you may need to configure. We sell the FlightCore stand alone, which is a low cost way to test the theory out as well, but I'm not seeing a huge risk on the system connection.

Hi @janis_blank , A quick browse of those range finders showed some with I2C interfaces. Now, we don't have all drivers possible starting in PX4, so this might not work out of the box. Here's the drivers available: https://github.com/modalai/px4-firmware/blob/modalai-1.11/boards/modalai/fc-v1/default.cmake#L17 There's a spare I2C port though likely available on the hardware for you, J13 on FlightCore: https://docs.modalai.com/flight-core-datasheets-connectors/#j13---i2c-display--i2c2-bus--safety-switch-connector You may need to enable drivers and then alter startup to get to work, here: https://github.com/modalai/px4-firmware/blob/modalai-1.11/boards/modalai/fc-v1/init/rc.board_sensors But in theory using I2C you should be able to get data from the range finders (it wouldn't be integrated into voxl-* tools, rather just used by PX4 though)

@janis_blank No, the needed SPI driver for the Lepton that goes in that socket has not yet been created.
