Interested to check out the LG290P breakout, but am unclear which RTK modes it supports e.g. does it only support RTK via L-Band or can it accept, say, RTCM3 via UART?
(the RTK Application Note appears to be a dead link - I checked on the Quectel site but not clear from the data sheet there either).
Yes to RTCM3
I can’t locate the broken link…the documents tab on the product page is working SparkFun Quadband GNSS RTK Breakout - LG290P (Qwiic) - GPS-26620 - SparkFun Electronics and the link at the end of the guide is working Reference - SparkFun LG290P Quadband GNSS RTK Breakout Hookup Guide …where are you seeing the 404 link from?
It also launched today, so the links may have been updated since your post
I can confirm… links were dead this morning when I replied w/ external links
