RAK1910 WisBlock GNSS Location Module Datasheet
Overview
Figure 1: RAK1910 WisBlock GNSS Location ModuleDescription
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.

- 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 |
