It's 10pm, do you know where your RTK prototypes are? 🔧🛰️🎯
We juuuuust plugged in this uBlox RTK F9P shield into USB and given the intense cost of these modules we definitely had a nervous twitch but then we heard the "ba-dunk" of enumeration and wheeeewww it came up as a serial port. Heartened, we soldered on a right-angle SMA connector and connected a chonky active antenna . Start up a copy of u-center and huzzah, there is GNSS data streaming out. Next up, we have to figure out what we want to use as the underlying transport layer from base station to rover - maybe an ESP32-S3 Metro and ESP-Now? more research is needed!
