Applications

• Drone Rescue Mode: Essential for Betaflight GPS Rescue to automatically return the drone if RC link is lost.
• Long-Range FPV: Provides flight speed, distance, and home direction arrows on your OSD (On-Screen Display).
• Autonomous Waypoints: Use with iNav or ArduPilot for planned autonomous missions.
• RC Fixed Wing: Stabilization and loiter modes for radio-controlled airplanes.
• Telemetry Logging: Record flight paths and speeds for post-flight analysis.

Project Evolution
From Freestyle to Long Range Explorer If you have mastered basic freestyle flying with a standard FPV drone, adding this Mini GNSS Module unlocks the "Long Range" class of flying.

• The Upgrade: A standard drone is blind to its position. By soldering this module to your Flight Controller's UART port, you unlock GPS Rescue, Speedometer, and Distance-to-Home on your goggles.
• Effort Level: Intermediate. Requires soldering 4 wires and configuring the "Ports" and "GPS" tab in Betaflight Configurator.
• Minimum Hardware: A Drone Flight Controller (F405, F722, or F411) with one free UART (TX/RX) pad.

Wiring Guide
Warning: Never swap VCC and GND. This will instantly destroy the module. Logic Voltage: This module is 3.3V and 5V tolerant. Most Flight Controllers provide 4.5V or 5V on the GPS pads, which is perfect.

Wiring Pinout (Cross-over connection):

• GPS VCC ➔ FC 5V (or 4.5V)
• GPS GND ➔ FC GND
• GPS TX (Transmit) ➔ FC RX (Receive)
• GPS RX (Receive) ➔ FC TX (Transmit)

Note: The TX of the GPS must go to the RX of the Flight Controller, and vice versa. Think of it as the GPS "Speaking" (TX) and the Flight Controller "Listening" (RX).

 Package Includes:

• 1 x RUSHFPV GNSS MINI M10 UBX NMEA Dual Protocol GPS Module for RC Airplane FPV Long Range

Frequently Asked Questions (FAQ)

• Will this GPS work with Betaflight Rescue Mode?
  Yes, this module is fully compatible with Betaflight GPS Rescue Mode. You must configure it in the "Ports" tab and enable "GPS" in the Configuration tab.
• How long does it take to get a GPS lock?
  Cold starts (first time powering up in a new location) typically take 1-3 minutes. Warm starts take only a few seconds. Always wait for a lock before arming.
• Does this module have a compass (magnetometer)?
  Most "Mini" class modules are GPS-only to save weight. If a compass is included, it will have two extra wires (SCL/SDA). Please check the physical wire count (4 wires = GPS only).
• Can I use this with Arduino?
  Yes, you can use the TinyGPS++ library with an Arduino. Connect to digital pins using SoftwareSerial or hardware Serial pins.
• Why is my GPS not showing up in Betaflight?
  Check that you have wired TX to RX and RX to TX. Also, ensure the Baud Rate in the "Ports" tab matches the module (try 9600, 38400, or 57600).
• Does it come with a battery for hot starts?
  Yes, it typically includes a small MS621 or similar rechargeable battery to store satellite data for quick hot starts.
• Is this module waterproof?
  No, the PCB and antenna are exposed. For wet conditions, you should conformal coat the board or use a waterproof heat shrink.
• Can I change the update rate to 10Hz?
  Yes, using u-center software (on PC) or via Betaflight passthrough, you can configure the refresh rate. 5Hz or 10Hz is recommended for drones.
• What is the voltage range?
  It operates safely between 3.0V and 5.5V. Do not connect it to the main battery voltage (VBAT); use the 5V BEC from your flight controller.
• Does it support GLONASS and Galileo?
  Most modern mini modules support multi-constellation (GPS + GLONASS/Galileo) for better coverage, though specific satellite support depends on the chipset firmware.
• How do I mount this on my drone?
  The antenna (ceramic patch) must face UP towards the sky. Keep it away from the VTX antenna and battery wires to reduce interference.
• Will this work with a Pixhawk flight controller?
  Yes, but Pixhawk users typically prefer modules with a built-in compass/magnetometer for better loiter performance. This is better suited for racing/freestyle drones.
• What connector does it use?
  These modules usually come with a JST-SH connector or simple solder pads. Check your specific package content.
• Why does the LED blink?
  Usually, a blinking PPS (Pulse Per Second) LED indicates that the module has achieved a 3D Fix (satellite lock). Solid light or no light usually means it is searching.
• Can I use this for a car tracker?
  Yes, as long as the microcontroller reading the data can parse NMEA sentences, it works for any tracking application.
• Is the antenna replaceable?
  No, the ceramic patch antenna is soldered directly to the PCB.
• What happens if I mount it upside down?
  Reception will be severely degraded or non-existent. The ceramic square must have a clear view of the sky.
• Does it work indoors?
  No, GPS signals are too weak to penetrate concrete roofs. You must be outdoors for a valid lock.
