BN-220 Dual GPS Glonass Module Navigation TTL Level 9600bps + GPS Passive Antenna for Arduino Raspberry Pi Pixhawk F3 CC3D Betaflight F4 Flight Control

Das GPS ist heute für eine meiner FPV gekommen und wurde direkt verbaut. Es macht grundsätzlich einen guten Eindruck und funktioniert. Ein Feldtest ist noch offen, die GPS Verbindung wurde in Betaflight aber erkannt. Es sollte also alles funktionieren.Warum ich nur 3 Sterne vergebe liegt an dem billigen Zubehör. Die Kabel sind kaum wärmebeständig. Selbst beim Löten mit niedrigen Temperaturen kann das Kabel kaum geklemmt werden ohne die Isolierung zu zerdrücken. Man darf das Kabel eigentlich nur leicht auf die Lötstelle legen/drücken. Es war eine riesige Fummelei…Wenn hier die Qualität noch steigt gebe ich auch gerne mehr Punkte.

Very good module. Works as expected. Easy to interface with raspberry pi.I got gps fix even inside the house

Using on a sub250 quadcopter. This replaced an HGLRC M80 GPS. Should have been the equivalent GPS, but it wasn't. Beitian locks up faster and retains lock on more satellites. This is my go to GPS unit. 4 wires and boom - great 3D GPS lockup in about 30 seconds. I run the GPS from a USB source for a few hours before I fly, so that the almanac data is current. Once you get on the field, this unit usually locks up in less than a minute and retains good lock for the entire flight. It is sensitive to interference from control radio and video transmitter, I keep a few inches between the GPS and the other radios.

Comes with long vinyl wires which are ~20cm in length. Would be nice if they were silicone, but that's fine. Has a little adhesive pad, too. Measurements fit perfectly for the 3d print i made to hold it on my quadcopter. Flashed and saved (which you can't do with the BN180) settings through ublox center to turn off QZSS and turn on Galileo and set the baud to 115k. Picks up satellites relatively quickly and really seems to hold on to them well, which is nice. The firmware that I use for my quadcopter, Betaflight, can flash most of these settings just fine, but sometimes it's touch and go - so it's nice to just have them permanently saved as is possible with the BN220.

Pretty easy to setup, only 4 wires to solder. As I recall, the diagram is from the bottom compared to when I waslooking at the decal side, so pay attention to polarity. The data lines are less critical, if the board doesn't get data,try switching the line to the pins on the board.I have cobbled together an 8 item menu sketch and added a BME-280 to the circuit to get temperature andto pressures, and to compute an altitude. The GPS altitude is generally more accurate though it will fluctuatedue to satellite geometry. On average though it is sufficiently accurate for my needs.I run it primarily on an ESP32 board and drive the menu using 2 wires to the touch pins to select the case thatI want to view. It can all be built in to a small package when using a 1.56" OLED screen.
