Interface summary

NOMAD exposes module-level interfaces for host communication, timing, antenna integration, and power design.

Main host interface

UART0_TX and UART0_RX provide the primary serial interface for host communication and receiver configuration.

Power supplies

VCC provides the main power-supply input. V_BCKP supplies the backup domain when the design requires retention of receiver data.

Timing and control

PPS provides timing output, EXINT accepts external synchronization events, and nRESET provides active-low reset control.

RF and antenna power

RF_IN and ANT_POWER support external GNSS antenna integration. Use a 50 Ω RF path between the module and antenna.

Pin descriptions

Use the following assignments when designing the carrier board. Leave unused NC pins unconnected. Verify the interface level of each signal before completing the schematic and PCB layout.
