what does the INT does in the NEMO M9N?

@copilot what does the INT does in the NEMO M9N?
1y
The INT (interrupt) pin in a GPS module like the NEO-M9N is typically used to signal external events or conditions to a microcontroller or processor. For example, it can be used to indicate the arrival of a new GNSS measurement, an alarm condition, or other asynchronous events that require immediate attention from the host system.
In your GPS Rover project, the INT net connects to J2:Pin_1. This might be intended to route the interrupt signal to a specific component or section within your design.
If you have further questions about integrating the NEO-M9N into your project or how to handle its interrupt signaling, feel free to ask!

what does the safe pin does?
1y
The SAFE pin on a GPS module like the NEO-M9N can be used to indicate or control safe states for the device or external circuitry. However, the specific use of the SAFE pin can vary depending on the manufacturer's design and intended application for the GPS module.
In some contexts, a SAFE pin might be used to:
  • Initiate a safe shutdown or power-down sequence.
  • Indicate that the GPS module is in a safe state and can be powered down without data loss.
  • Control external circuitry to ensure it operates within safe limits when certain conditions are met.
In your GPS Rover project, the SAFE net connects to J2J2:Pin_2. This connection might be used to manage or monitor safe states within your circuit.
To get the exact functionality of the SAFE pin in the NEO-M9N, I would recommend checking the module's datasheet or reference manual for detailed information specific to the part. If you need help with how this pin impacts your design, feel free to ask!

reset and PPS should be connected to the MC GPIO?
1y
For a GPS module like the NEO-M9N, it is common to connect certain pins such as RESET and PPS (Pulse Per Second) to the GPIO pins of a microcontroller to enable specific functionalities. Here's a brief explanation of each:
  • RESET: This pin is typically used to reset the GPS module. Connecting it to a GPIO pin on a microcontroller allows the microcontroller to reset the GPS module programmatically. This can be useful for recovering from errors or reinitializing the module under software control.
  • PPS (Pulse Per Second): The PPS output provides a high-accuracy timing pulse once per second. This is useful for precise timekeeping or synchronization purposes. Connecting the PPS pin to a GPIO pin on the microcontroller enables the microcontroller to use this pulse for timing applications.
In your GPS Rover project, the RESET net is connected to J2J2:Pin_3, and the PPS net is connected to J2J2:Pin_4. If J2J2 is interfacing with a microcontroller, these connections align with the typical use case for such pins.
Would you like help with interfacing these with a specific microcontroller, or do you have other questions about the setup?
