Readytosky M8N GPS Module Built-in Compass with GPS Antenna Mount for Standard Pixhawk 2.4.6 2.4.8 APM 2.6 2.8 Flight Controller

I could not calibrate the compass on a Tarot quadcopter I just built. The unit I was using was salvaged from a crash; ;thinking that it may have been damaged, I bought this one. The module arrived on time, and as soon as I installed it I was able to complete a successful calibration. I have not yet flown the aircraft as I am waiting on a receiver, but I expect it to work just fine.

Purchased this for my drone kit. It easily connects right in and the stand has an added threaded hold in the bottom which made mounting it very easy. The stand keeps it away from all you other drone electronics to give a clear signal. The price and functional integration I to the Pixhawk is great.

Finally got the drone ready, but after a few attempts to fly, the compass stopped working. Gps does worj but compass not.

I had two. One with the kit that never worked and the second worked I believe but I had disable prearm gps fix in mission planner due to the troubles with the first resulting in a crash. The second has not been able to gain a fix stable enough for flight since. For the $60 required to get something working might as well try brand name gear.

I ordered this GPS to use with my autopilot and as I received it I opened the case to see inside and make sure that it's original Ublox and it was. I used u-center program and as I connected the GPS it gave me 3 satellites in my home under the roof which is great. Also it has external compass that its very necessary, you can't trust internal compass on the autopilot board.

Included everything shown in the photos, nicely packaged.Disassembled it, so I could figure out the wiring, and connect it up to a Beaglebone Blue (had to change plugs). PCB has informative silk for those "do it yourself" projects.Had some difficulty screwing the pole into the upright position, but found out a set screw was sticking out too far. Because the flat on the pole is tapered, I simply raised the pole a bit and the set screw was able to go in further.PinoutsIf you can't read the photo, the labels are (from top to bottom) SCL, SDA, TXD, RXD, GND, VCC.TXD and RXD are with respect to the GPS chip, so connect RXD to the Beaglebone UART_TX line and TXD to the Beaglebone UART_RX line. VCC was connect to 5V. Signals (SCL, SDA, TXD) are 3.3 volt level.Arducopter detected the GPS and compass on the first try.

I bought two of these GPS units from readytofly, and neither of them worked reliably. One of them worked only intermittently with most of the time not working, the other never worked at all. By not working I mean the flight controller (Pixhawk) does not get any or enough GPS satellites to establish the "3D fix" state.To fix the issue, I bought a "Geekstory Beitian BN-880 GPS Module U8", and it worked immediately out of the box. It acquired 10 satellites.All three units (two readytosky which did not work, and one Geekstory which worked) are shown in the picture.

Love Ready to Sky!They have great products and super good quality at affordable prices!!This GPS is one of the best I have been using in my new Quad fast and accurate positioning.Thank you!!!
