Description

The RAK1910 WisBlock GNSS Location Module module, part of the RAK Wireless Wisblock series, is a u-blox MAX-7Q GNSS (GPS, GLONASS, QZSS, and SBAS) module. This module features exceptional performance, high sensitivity, and minimal acquisition time, which makes it suitable for low-power IoT solutions. The RAK1910 positioning module is a GNSS receiver. It receives and tracks the GPS (including SBAS and QZSS) and the GLONASS signals. QZSS and SBAS signals (by default) can be received concurrently with GPS signals.

Features

• Voltage Supply: 3.3 V
• Current Consumption: 15 uA to 22 mA
• Chipset: u-Blox MAX-7Q
• High accuracy of 2.5 m
• Update rate: 10 Hz
• Velocity accuracy: 0.1 m/s
• Heading accuracy: 0.5 degrees
• Fast location fix. 29 sec from cold start to first fix. 1 sec from hot start
• GPS and GLONASS satellite support
• Module size: 10 x 23 mm

NOTE

• Only the UART-related pins, 1PPS pin, RESET pin, VDD, and GND are connected to this module.
• The RAK1910 module can be installed in the Slot A only.

If a 24-pin WisBlock Sensor connector is used, the IO used for the output pulse depends on what slot the module is plugged in. The following table shows the default IO used for different slots:

SLOT A	SLOT E	SLOT F
WB_IO1	WB_IO4	WB_IO6
