SparkFun MicroMod GNSS Function Board - NEO-M9N
201 units available with a short lead time.
The SparkFun MicroMod GNSS Function Board features a u-blox NEO-M9N 92-channel GNSS receiver, supporting concurrent reception of GPS, GLONASS, Galileo, and BeiDou constellations with approximately 1.5 m horizontal accuracy. It connects to a MicroMod Main Board via the solderless M.2 connector and communicates over UART, SPI, or I²C.
An onboard rechargeable battery backs up the RTC, reducing time-to-first-fix from 24 seconds (cold start) to approximately 2 seconds (hot start). The module includes jamming and spoofing detection, a built-in SAW filter with LNA, and is configurable via the SparkFun Arduino library or u-blox u-center software.
