NEO V2 PRO GNSS receiver
[! TIP] NEO v2 Pro has been discontinued, it is recommended that you choose NEO 3 Pro GPS, which has a more advanced M9N positioning module and better performance.
Overview
Neo V2 pro is a GNSS receiver based on UAVCAN communication protocol. It integrates industrial-grade compass, barometer, flight controller status light, buzzer, and safety switch in one. It has the characteristics of high safety and strong anti-interference. .

NOTE Ardupilot 4.0 and above firmware perfectly supports NEO V2 Pro; PX4 is not yet fully compatible with NEO V2 Pro (such as safety switches and buzzers cannot work).
Features
1.UAVCAN standard protocol, high real-time, strong anti-interference
2.Industrial sensor(RM3100), adapt to complex magnetic field environment
3.High-performance processing unit
4.internal high-precision barometer to meet the needs of different application scenarios.
5.Open source code to load custom programs.
6.Adopt SAW + LNA + SAW dual filtering design, which can effectively avoid the impact of GPS positioning reception from remote control, digital transmission, and 4G signals.

Connect to v5 +

- Please connect it to the flight control CAN1 / CAN2 interface (CAN1 is recommended)
NOTE The connection of other PIX flight controllers is the same.
Enable
you need to set flight control parameters to enable Neo V2 pro; there are different setting methods according to the flight control firmware.
ArduPilot firmware
Set the following parameters in all parameter tables of Mission planner and restart after writing
CAN_P1_DRIVERset to 1.CAN_P2_DRIVERset to 1.NTF_LED_TYPESset to 231.GPS_TYPEset to 9.
