    Hi Mark,

    I'm trying to connect your gps-imu on a RPI3.

    But it looks like it's not responding.

    Here's a picture of the mounting

    gps-imu

    Nothing is coming out of

    minicom -b 9600 -o -D /dev/serial0

    or from screen /dev/serial0 9600

    I'm not sure if I have to add a power wiring to the  mounting.

    Could you please tell me where I've got it wrong ?

    Should I solder the wiring?

    You'll find bellow the information

    Thank you very much in advance.

    Patrice

    Hi Patrice.

    You need to solder the header on.
