M9N GPS
Couldn't load pickup availability
Description
The M9N GPS uses multi-constellation GNSS powered by u-blox M9N, a concurrent GNSS receiver which 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 compass, tricolored LED indicator, buzzer, and a safety switch. There are 3 different connectors 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, rechargeable backup battery for warm starts.
