NEO-M9N - Data sheet 1 Functional description 1.1 Overview The NEO-M9N module is built on the robust u-blox M9 GNSS chip, which provides exceptional sensitivity and acquisition times for all L1 GNSS systems. The u-blox M9 standard precision GNSS platform, which delivers meter-level accuracy, succeeds the well-known u-blox M8 product range. The receiver also provides higher navigation rate and improved security features compared to previous u-blox GNSS generations.

NEO-M9N - Data sheet 4 Electrical specification The limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only. Operation of the device at these or at any other conditions above those given below is not implied. Exposure to limiting values for extended periods may affect device reliability.

NEO-M9N - Data sheet 5 Communications interfaces There are several communications interfaces including UART, SPI, I2C8 and USB. All the inputs have internal pull-up resistors in normal operation and can be left open if not used. All the PIOs are supplied by VCC, therefore all the voltage levels of the PIO pins are related to VCC supply voltage. 5.1 UART interface There is one UART interface: UART1, which operates up to and including a speed of 921600 baud. No hardware flow control is supported.

NEO-M9N - Data sheet s. The interface stretches the clock when slowed down while serving interrupts, therefore the real bit rates may be slightly lower. The I2C interface is only available with the UART default mode. If the SPI interface is selected by using D_SEL = 0, the I2C interface is not available.

NEO-M9N - Data sheet 5.4 USB interface A USB interface, which is compatible to USB version 2.0 FS (Full Speed, 12 Mbit/s), can be used for communication to a host. The VDD_USB pin supplies the USB interface. 5.5 Default interface settings Interface Settings UART 38400 Baud, 8 bits, no parity bit, 1 stop bit. Output messages: NMEA GGA, GLL, GSA, GSV, RMC, VTG, TXT (no UBX). Input protocols: UBX, NMEA and RTCM 3.3. USB Output messages activated as in UART. Input protocols available as in UART.
