GNSS Timing Breakout - ZED-F9T (Qwiic) + Mosaic X5 Qs

Qwiic System

Hi,

  1. WIll this fit inside the SparkFun RTK mosaic-X5 enclosure? Can I drill 3 SMA holes and mount it on a blank wall?
  2. If I connect this to the SparkFun RTK mosaic-X5 using a Qwicc cable, will the ZED-F9T have internet access via the Mosaic board’s ethernet or wifi?
  3. How can I push / pull RTCM corrections between this and the Mosaic X5 receiver over SPI / Qwicc (no TCP)?

The SparkFun RTK mosaic-X5 comes in an aluminium enclosure designed specifically for its components. Detailed dimensions of this enclosure are available in the product manual.

To determine if the ZED-F9T can fit inside this enclosure, you’ll need to compare its dimensions with the available space inside the mosaic-X5 enclosure.

What is “this”?

Hi @Strykar ,

The ZED-F9T should fit inside the RTK mosaic-X5 case. There a quite a lot of spare room inside. But please tell us more about your application. Why do you want to connect those two devices? The easiest way to transfer RTCM is over a UART connection. To use Qwiic, Ethernet or WiFi, you would probably need to write custom firmware for the ESP32.

Best wishes,
Paul

I was wondering if the F9T could replace this GPSDO to provide a 24 Mhz reference input to an SDR and a (1.8V - 3.3V) 1PPS signal to an Intel XXV710 network card that can receive two (configurable) 1PPS inputs via 50 ohm SMA for PTP.
I will probably rackmount the Mosaic X5 enclosure and was looking to keep things tidy.

Sounds neat; update this thread with results if you end up testing the enclosure combo

Worst-case you can always measure stuff and have someone on fiverr (or similar) design a 3d printable one for ya for like $20 and then get it printed/shipped for another $20…or DIY if you use CAD and know someone with a 3d printer

Hello my friend , Were you able to install this setup you mentioned? I work with sdr and the same gpsdo.
