The board features three UART ports, which are accessible through the USB-C connector, BlueSMiRF *(6-pin PTH)* header , and 4-pin locking JST connector. Users can also interface with the board through the 24 PTH pins that are broken out around the edge of the board. For the GNSS antenna, an SMA antenna connector is provided on the edge of the board; additionally, there are also SMD pads for another *(RP-)*SMA connector to output a PPS signal. We also provide two 4-pin JST Qwiic connectors for future use, when the I<sup>2</cup> feature becomes available for the GNSS module.
