{"title":"SparkFun MicroMod GNSS Function Board - NEO-M9N","handle":"sparkfun-micromod-gnss-function-board-neo-m9n","url":"/products/sparkfun-micromod-gnss-function-board-neo-m9n","description":"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.\n\nAn 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.\n\nKey Features\n\n\n92-Channel u-blox NEO-M9N – GPS, GLONASS, Galileo, and BeiDou (4 concurrent)\n\n1.5 m Horizontal Accuracy – High-precision positioning\n\n25 Hz Max Update Rate – Fast position updates\n\nHot Start in ~2 s – Rechargeable RTC backup battery\n\nJamming and Spoofing Detection – Built-in SAW filter and LNA\n\nMicroMod M.2 Connector – Solderless connection to Main Board\n\nUSB-C – For module configuration with u-center\n\nU.FL Antenna Connector – Connect your choice of GNSS antenna\n\n\nSpecifications\n\n\nReceiver – u-blox NEO-M9N, 92 channels\n\nConstellations – GPS, GLONASS, Galileo, BeiDou (concurrent)\n\nAccuracy – 1.5 m horizontal, 0.05 m/s velocity, 0.3° heading\n\nUpdate Rate – Up to 25 Hz\n\nTTFF – Cold: 24 s, Hot: 2 s\n\nMax Altitude – 80,000 m\n\nMax Velocity – 500 m/s\n\nCurrent (tracking) – 27 mA (GPS only), 31 mA (GPS+GLONASS), 36 mA (all four) @ 3.0 V\n\nVoltage Regulator – 3.3 V / 600 mA (AP2112K)\n\nProtocols – NMEA, UBX, RTCM over SPI, USB, UART, or I²C\n\nBattery Backup – 1.5 mAh rechargeable for RTC\n\n\nPackage Contents\n\n1× SparkFun MicroMod GNSS Function Board (NEO-M9N)\n\n\n\nNote: A GNSS antenna, MicroMod Processor Board, and MicroMod Main Board are required but not included.
