NEO-M9N-00B - Overview

GPS Breakout NEO-M9N-00B​

The GPS Breakout NEO-M9N-00B is a GNSS positioning module based on the u-blox NEO-M9N receiver. It concurrently receives GPS, GLONASS, Galileo, and BeiDou signals, reaching up to 2.0 m CEP horizontal accuracy, and connects over I2C, UART, or SPI via two Qwiic connectors or a standard pin header.

Beyond position output, the module includes a configurable 1PPS timepulse, a jumper-selectable antenna bias voltage for active antennas, and an onboard CR1220 backup battery holder for faster fixes after a power cycle. It can be configured and monitored with u-blox's free u-center desktop software.
