I noticed my NTRIP casting was not working and found my RTK Reference Station to be seemingly dead. I verified the USB power supply was working properly, but was unable to get the status LED to light or anything to come on the screen. I’ve held the reset button for various lengths of time, and tried different power supplies, the PoE port, etc. Just haven’t been able to get a single light to show on this thing.
Any suggestions for how I can troubleshoot this further? Always happy to explore and learn, but this level of PCBA is a bit over my head.
Or what other support options I may have? A quick review of other threads made me think I might be able to get RMA-type support?
I haven’t seen a Reference Station just die before… That’s a new one for me. Can you send me a private message with your order number? We may need to just get it back here for analysis and either repair/replace. If it is still in the warranty period, we will just replace it for you.

Oops, sorry Russell, didn’t mean to step on your toes there.
Yes, I have a suitable PSU to try powering the board per that link you sent. I saw on other similar threads to try reflashing the ESP32 firmware. I’ll have time to try both of these things probably tomorrow. Will follow up, thanks!
We are looking forward to it. If you are still able to communicate with the ESP32, but there is no visual indication that the unit is powered, the mystery deepens.
@TS-Russell: Attempting to wire an external DC power supply, I’m a bit confused…the link above leads to some (excellent) documentation for a mosaic X5 board which is different than the reference station board I’m working with:
Man you folks have fantastic documentation! I easily found the correct (I think) schematic for the reference station on your github, but all the V_in/Pw contacts appear to be associated with the POE power source on the RJ45 connector, which is a different voltage range than the 9-36 you were suggesting.
Figured I should clarify before applying any voltage to the board. Thanks for the guidance! Will see if I can connect to the ESP32 now…running out of time this evening.
OK, a bit of good progress here. I decided to see if I could probe the POE voltage at PW+/PW- , mostly out of curiosity for what a new switch was putting out.
In the course of snapping a photo, I noticed the status light had begun blinking! Checked my network and the ESP32 had joined so that seems like it can at least still be powered by POE. The front display is still blank though. Over the weekend I will try connecting to the ESP32 and updating the firmware.
I wonder if it’s possible the firmware could have been a bit corrupted or something by the slow death of a voltage regulator on the USB-C power source…
I’m not sure what we use, but usually either heat or isopropyl alcohol helps the gooey to get ooey…the good news you can’t really break it MORE, y’know? Just disconnect that qwiic cable and go nuts
Hot glue, epoxy, or similar should be fine for the new one
