GEP-M8Q GPS Module

FAQ

1. What is GEP-M8Q?
GEP-M8Q is a bold attempt by the GEPRC team. It integrates the QMC5883L magnetometer and MS5611 barometer into the GPS module. It is a three-in-one multifunctional GPS module.

2. What is the difference between GEP-M8Q and the previously released GEP-M8U module?
M8Q adds QMC5883L magnetometer and MS5611 high precision magnetometer.

3. What should be paid attention to when installing GEP-M8Q?
Because the GPS module integrates a magnetometer and a barometer, care should be taken to keep away from magnetic interference during installation to avoid abnormal magnetometer data. In addition, the attached sponge needs to be covered above the opening of the barometer to reduce airflow interference.

4. Can GEP-M8Q be used on Betaflight?
It can be used on Betaflight, but because Betaflight’s support for magnetometer and barometer is not perfect, only GPS function can play a full role, so it is recommended to buy GEP-M8U GPS module when using Betaflight.

5. The flight controller already has a BMP280 barometer, can I still use the MS5611 barometer on the GEP-M8Q?
Yes, BMP280 and MS5611 are connected to the flight controller at the same time without conflict. Taking INAV as an example, you only need to set the barometer to MS5611 in the ground station to use it.

6. The flight controller already has a built-in MS5611 barometer, can I still use the MS5611 on the GEP-M8Q?
No, it will create a conflict and will not work properly.

7. How to set the GPS protocol and baud rate of GEP-M8Q?
The GPS is set to ublox, and the baud rate is set to 115200.

8. What is the installation direction of GEP-M8Q?
The GEP-M8Q module can be installed in any direction, just set the direction of the magnetometer in the ground station. If you install it according to the arrow on the module, set the direction of the magnetometer to CW 180° flip.

9. There are two versions of GEP-M8Q, how to choose?
M8Q has two versions: GPS+GLONASS and GPS+BDS. It is recommended to use the GPS+BDS version in the Asia-Pacific region, and the GPS+GLONASS version is recommended for customers in other regions.

10. Can the GEP-M8Q be used to achieve the effect of fixed height and fixed point?
GEP-M8Q is just a GPS module integrated with magnetometer and barometer, and the realization of the fixed-altitude and fixed-point function is carried out by the flight controller.
