RTK with the output to "5 Hz Nav+IMU Custom"
For the PPKOORD with RTK activation, you normally use the main connector (Pin 4: RX TTL 3.3V) for inject the RTCM messages, at 115200 baud.
But, if you choose the output to "5 Hz Nav+IMU Custom", this pin 4 is disabled for this use. Instead, use the alternative RX TTL 3.3V pin signaled in the picture for inject the RTCM messages, at 38400 baud. This alternate port will also work for the rest of output modes for inject the RTCM messages.
By default this port is unpopulated. The most easy way to enable it is to solder two-pin header, then plug some connector with a wire.
