    Has anyone used these successfully? When inspecting the traces, I’ve noticed that connections match up like this:
    (Top Left) —– (Top Right)
    Gnd ———– Gnd
    Vin ———– Batt
    Gnd ———– Gnd
    Gnd ———– Rx
    GPIO ———– Tx
    Which maps to the pins:
    1 ———– 2
    3 ———– 4
    5 ———– 6
    7 ———– 8
    9 ———– 10
    However, when I attempt to connect it to my ublox connector, I can’t get it to mate properly. When looking at the ublox on the bench, it has the following pin-out when looking at the connector and the helix antenna is pointed to the left:
    upper left —- upper right
    10 ———– 9
    8 ———– 7
    6 ———– 5
    4 ———– 3
    2 ———– 1
    Now when I flip the ublox onto the interface board, the pins line up like so:
    10 -> 2 ———– 9 -> 1
    8 -> 4 ———– 7 -> 3
    6 -> 6 ———– 5 -> 5
    4 -> 8 ———– 3 -> 7
    2 -> 10 ———– 1 -> 9
    I verified that the ublox connector Pins 1,2,5,6 and 7 are all inter-connected. Therefore, when I apply power to the Vin port (breakout pin 3 / ublox pin 7), I’m creating a short directly to ground.
    I tried to turn the board 180 degrees to see if it worked that way, but the pins still didn’t allign. My assumption is that the pinout of the breakout board is incorrect, and was wondering if anyone else had noticed this issue
    Thanks
