NEO 3x GNSS DroneCAN Module with IP66 Waterproof and Dustproof

Simultaneous reception of four satellite systems (BeiDou, Galileo, GLONASS, GPS).
DroneCAN communication protocol.
Triple filtering design (SAW + LNA + SAW).
IP66 dust and water resistance design.

IP66 Dustproof And Waterproof

The NEO 3x is designed with an IP66 dust and water resistant structure and plug, allowing your drone to fly in rainy weather and unlock more flight scenarios.

u-blox M9N GNSS Receiver

It uses a high-performance ublox M9N GNSS receiver with with concurrent reception of 4 GNSS, and the highest measured accuracy can reach 0.7m.

Built-in STM32F4 Processor

NEO 3x uses an STM32F4 processor with a 100 MHz Cortex®-M4 core supporting floating-point arithmetic units to run the implementation system.

RM3100 Industrial Compass

Using RM3100 industrial grade compass, it has stronger anti-interference performance and can also be used as a backup sensor.

Triple Filter Design

NEO 3x adopts SAW+LNA+SAW triple filtering design to effectively avoid the impact of signals from remote controller, telemetry, and mobile networks on GPS positioning reception.
