NEO-7 - Data Sheet 1.4 Block diagram Figure 1: NEO-7 block diagram 1.5 GNSS u-blox 7 positioning modules are GNSS receivers and can singly receive and track GPS, GLONASS, or Galileo signals. QZSS signals may be received concurrently with GPS signals. 1.5.1 GPS u-blox 7 receivers are designed to receive and track the L1C/A signals provided at 1575.42 MHz by the Global Positioning System (GPS). 1.5.
NEO-7 - Data Sheet 1.6 Augmented GNSS For more details about augmented GNSS, see the u-blox 7 Receiver Description Including Protocol Specification [2]. 1.6.1 Assisted GNSS (A-GPS) A-GPS improves GNSS performance by delivering aiding data to the GNSS receiver via wireless networks or the Internet.
NEO-7 - Data Sheet 1.8 EXTINT: External interrupt EXTINT is an external interrupt pin with fixed input voltage thresholds with respect to VCC. It can be used for control of the receiver or for aiding. For more information about how to implement and configure these features see the u-blox 7 Receiver Description including Protocol Specification [2] and the MAX-7 / NEO-7 Hardware Integration Manual [1]. 1.8.
NEO-7 - Data Sheet 1.11 Interfaces A number of interfaces are provided either for data communication or memory access. The embedded firmware uses these interfaces according to their respective protocol specifications. 1.11.1 UART NEO-7 modules include one UART interface, which can be used for communication to a host. It supports configurable baud rates. For supported baud rates see the u-blox 7 Receiver Description Including Protocol Specification [2]. 1.11.2 USB A USB version 2.
NEO-7 - Data Sheet 1.13 Power management u-blox 7 technology offers a power-optimized architecture with built-in autonomous power saving functions to minimize power consumption at any given time. An integrated high efficiency DC/DC converter allows low power consumption even for higher main supply voltages. The receiver can be operated in two operating modes: Continuous Mode or Power Save Mode.
NEO-7 - Data Sheet 2 Pin Definition 2.
NEO-7 - Data Sheet 3 Configuration management Configuration settings can be modified with UBX configuration messages. The modified settings remain effective until power-down or reset. If these settings have been stored in battery-backup RAM, then the modified configuration will be retained, as long as the backup battery supply is not interrupted. With the NEO-7N, configuration settings modified with UBX configuration messages can be saved permanently.
NEO-7 - 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 and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to these limits for extended periods may affect device reliability.
