Used RTK Facet about 4-6 times since purchase 2 weeks ago no problem. Attempted to turn it on yesterday, nothing, power / set up button pressed and held no screen illumination. When charging through USB port green LED illuminates only. Not much use in this condition. Anyone had this issue or has any ideas how to fix?
May be running out of battery charge. Have you recharged the battery?
Same here. Worked great for months. The charge light goes on, appears to charge, and goes off. If I hook up a USB C to my desktop, the COM CH340 shows up on the desktop.
I have just got this exact same problem.
How can this be fixed?
Checking in to see if anyone could shed some light on this.
Not much good in this condition. Does make a great doorstop.
I have the same problem has anyone found a solution ?
I’m not aware of one and look forward to Sparkfun Support for this issue.
Have you tried using the firmware update tool to reset the esp32? Ours does this all the time. It is powered on but unresponsive with nothing on the screen. Requires a PC to reset it. This thing needs a hard reset button so badly. I can’t believe they did not include one.
I was able to get my facet to turn on , did nothing to it other than press power on button had shown full battery , turned it off and back on several times seemed to work fine , took it out into the field and would not turn on again , tried to turn it on a few more times back home and nothing , does anybody have any idea how to get a hold of tech support ?
Any updates on the topic? Worked fine for months and now it just won’t turn on after being fully charged…
Have you connected to a pc? Every time thsat has happened to ours so far we still had a functioning usb connection to use to reset it
When I plug it in, my PC knows there’s something there but can’t access it. Is there a guide somewhere on how to reset it? Can it be done manually? thks!
Download the firmware update tool. Run it and it has a button to reset the esp32. Click it and it will come back to life.
Still praying for it to come back to life… 
I reset the ESP32 and I looked through Tera Term and the antenna is still producing NMEA but…still won’t turn on. I’m openned to any suggestions…
(I also tried to update the firmware withhout success…)
Does it respond to commands in The terminal?
