Description The M9N GPS uses multi-constellation GNSS powered by u-blox M9N, a concurrent GNSS receiver that can receive and track multiple GNSS systems. Owing to the multi-band RF front-end architecture, all four major GNSS constellations, GPS, Galileo, GLONASS, and BeiDou, can be received concurrently.It also comes with the IST8310 or IST8308 compass, tricolored LED indicator, buzzer, and a safety switch. There are 3 different connector options for different purposes. This module ships with a baud rate of 115200 (38400 previously). The high-gain 25 x 25 mm2 patch antenna provides excellent performance, and the omnidirectional antenna radiation pattern increases flexibility for device installation. It features active circuitry for the ceramic patch antenna and a rechargeable backup battery for warm starts. Feature Ublox M9N GNSS Receiver Accurate Positioning Fast Navigation Update Rate IST8310 or IST8308 Compass High-gain 25*25*4mm antenna Internal Buzzer, Safety switch Ultra Bright UI RGB LED Note IST8308 is supported by PX4 V1.16.0+ on Pixhawk 6C and 1.14.3+ on Pixhawk 6X The Status LED driver has changed. This LED is supported in PX4 1.14, ArduPilot 4.4.0 & later.
